Cable terminals comparison 2026

The best cable terminals, compared.

Top pick: TOPCZY tinned copper lugs Best value: Gorffy 300 insulated crimps – Lowest price here with a four-figure review count: about £7.29, 4.5 from 2,780 reviews, score 86 after brass, 120 V and flimsy spades. Updated 22.10.2026.

Cable terminals on amazon.co.uk cover four jobs, and a piece count will not tell you which one you are buying. Judge each box by conductor size, the stud or clamp, the metal and the die. BS 7671 Section 526 requires a sound connection. Regulation 526.9 requires a suitable terminal or end treatment for fine strands. A claim that a box meets all electrical standards is not a BS 7671 certificate. Fixed wiring and EV high-voltage pins stay with a competent person. Family, size and tool are set out in the [cable terminals buying guide](/hub/electrical-equipment/cable-terminals/sub/cable-terminals-buying-guide). Insulated crimps use a ring, fork, spade, bullet or butt. Tubular copper lugs, bootlace ferrules and lever blocks do different jobs. UK trade guides use red for about 0.5–1.5 mm², blue for 1.5–2.5 mm² and yellow for about 4–6 mm². Gorffy's 300-piece listing starts yellow at 2.5 mm². Those colours are not the French or German ferrule codes. Electric French code is 0.5 white, 0.75 blue, 1.0 red, 1.5 black and 2.5 grey. A red ferrule is not a 0.5–1.5 mm² crimp, and red is not a live conductor.

Cable terminals on amazon.co.uk cover four jobs, and a piece count will not tell you which one you are buying. Judge each box by conductor size, the stud or clamp, the metal and the die.

The best cable terminals in detail

TOPCZY tinned copper lugs

Rank 1

TOPCZY tinned copper lugs

Our view

TOPCZY lists tinned copper lugs from 6 mm² to 25 mm² with M6 and M8 holes at £7.29, and the bullet adds pre-cut heat-shrink at 35 mm and 45 mm. The title, the number of items and the unit count say 100 pieces, while one bullet says 200 pieces including the heat-shrink, and Included Components says NO. The colour field says gold and the contact field says tinned copper, so the finish on the page is not one description. Voltage and current are blank, and there is no crimp tool. The star line is 5.0 from one rating, and there is no review text at all, so there is nothing to read about fit, heat, or whether the sleeves actually shrink. A single perfect rating is not a sample. Open this listing only if the live amazon.co.uk page settles the count, because the listing does not show how the crimp behaves.

Pros

  • 6–25 mm² lugs with M6 and M8 holes at £7.29
  • The bullet lists pre-cut heat-shrink at 35 mm and 45 mm
  • Tinned copper is named in the contact field
  • The shelf price is level with the cheapest multi-size lug packs here

Cons

  • 5.0 from one rating, and there is no review text
  • The title says 100 pieces and a bullet says 200 including heat-shrink
  • The colour field says gold
  • Voltage, current and a crimp tool are all absent

Best for: A buyer who has checked the current amazon.co.uk photos for the count and the heat-shrink, and who only needs 6–25 mm² lugs.

Less suitable: Anyone treating a single 5.0 rating as proof, or a connection that needs a printed voltage.

Common questions

Is heat-shrink in the box?

Is the count 100 or 200?

The title says 100. One bullet says 200 pieces including heat-shrink, packed in a plastic box.

The listing line is 5.0 from 1 rating. There is no review text. Voltage and current are not stated.

QLOUNI open-barrel pin kit

Rank 2

QLOUNI open-barrel pin kit

∼£30

Our view

QLOUNI's open-barrel pin kit is £29.98 and lists 28 male pin series, 400 wire seals, an open-barrel crimper, 18 removal tools and tweezers. Conductor bands run from 0.2–0.75 mm² up to 0.5–1.5 mm² depending on the series, the contact is copper, and the bullet says the kit is not universal. It excludes some proprietary OEM connectors, ECU and micro terminals, high-current battery connections, safety-critical vehicle connectors, and EV high-voltage pins. The listing is 4.8 from 29 reviews, but only two United Kingdom reviews are captured, and neither describes a crimp or a vehicle the pin fitted. The title says 970 pieces, the unit count says 969, and a bullet splits the contents as 550 terminals plus the seals and tools. No captured review names which of the 28 series actually fitted a housing. It is a workshop pin assortment only after you have matched the shape, the width and the locking tab, and it is the wrong box for an EV connector.

Pros

  • Open-barrel crimper, 18 removal tools, tweezers and 400 seals at £29.98
  • 28 series with printed conductor bands
  • Copper contacts are stated
  • The listing states the exclusions, including EV high-voltage pins

Cons

  • 4.8 from 29 reviews, with only two UK texts and no fitted connector described
  • Not a universal kit
  • The piece count is 970, 969, or the bullet's split
  • Voltage and current are not printed

Best for: A known open-barrel pin you have already matched to a housing that is not on the exclusion list.

Less suitable: EV high-voltage pins, a battery lug, or a first guess at an unnamed ECU plug.

Common questions

Will this kit fit every vehicle connector?

No. The bullet says it is not universal and excludes some proprietary OEM connectors, ECU and micro terminals, high-current battery connections, and safety-critical vehicle connectors.

Does it include EV high-voltage pins?

No. The bullet excludes EV and high-voltage systems.

How many UK reviews describe a fitted connector?

Two reviews are marked United Kingdom. Neither describes a crimp or a vehicle fit. The listing total is 29.

Okeno Select 40 lever blocks

Rank 3

Okeno Select 40 lever blocks

Our view

Okeno Select lists 40 lever blocks at £7.99, with solid cable to 4 mm² and flexible cable to 2.5 mm². The spec line prints 250 V and 32 A, while a bullet also prints 600 V, and the housing is PA66 and PC with nickel-plated copper contacts. Thirteen captured reviews, all marked United Kingdom, against a listing total of 41 at 4.7 stars, call them a quick clamp that fits a shallow space because the body is long and thin. One reviewer supplied 5 A to 12 V lights and said the block did not warm up. None of those 13 reviews checks the 32 A figure or the 600 V bullet. There is no repeated broken lever in that small set of reviews, and no storage case is listed. It is the lever in this set that actually prints a current, if you treat 32 A and 600 V as untested listing text and stay inside 2.5 mm² on flexible cable.

Pros

  • 40 lever blocks at £7.99, with 32 A and 250 V on the spec line
  • Flexible cable listed to 2.5 mm² and solid cable to 4 mm²
  • 4.7 from 41 reviews, with 13 captured texts marked United Kingdom
  • UK reviews praise a secure, tool-free clamp in a shallow space

Cons

  • A bullet also prints 600 V, and no captured review checks 32 A or 600 V
  • Only 41 ratings, against 6,474 on the other lever pack
  • No storage case is listed
  • Flexible cable stops at 2.5 mm²

Best for: A lighting join where you want a printed 32 A line and a thin body that fits a shallow space.

Less suitable: A buyer who wants a large review sample, or flexible cable above 2.5 mm².

Can the lever be opened again?

The listing describes the lever as reusable. No storage case is listed in the specs.

flintronic 34 lever connectors

Rank 4

flintronic 34 lever connectors

Our view

The flintronic pack gives you 34 SPL-1 lever connectors at £7.98, and the first 50 amazon.co.uk reviews, all marked United Kingdom, describe a tight clamp that is faster than a screw terminal. Reviewers clip the blocks into several ways, including a ceiling fan with 12 wires, and one person used them for a temporary join in a car. Amazon.co.uk shows 4.6 from 6,474 reviews, the largest sample in this set. Solid cable is listed from 0.2 mm² to 4 mm² and flexible cable only to 2.5 mm², at 250 V, with current left blank. The title says 34 pieces, the unit-count field says 50, and one review describes a set of 24, so the number in the box is not settled on the page. One captured review says a lever broke off and the connector still worked, and another reviewer keeps these blocks on 3–12 V circuits and avoids 240 V. It is the top pick here for a reusable lighting join inside the printed sizes, once you check the piece count on the day you buy.

Pros

  • 34 SPL-1 levers that clip into 2, 3, 4 or 6-way, at £7.98
  • 4.6 from 6,474 reviews, with the first 50 texts marked United Kingdom
  • UK reviews praise a tight clamp, including a ceiling fan with 12 wires
  • Solid cable 0.2–4 mm² and flexible cable to 2.5 mm², 250 V listed
  • The listing describes the lever as reusable

Cons

  • Piece count conflicts: title 34, unit count 50, one review says 24
  • Listed current is not on the spec lines
  • One captured review of a lever breaking off
  • One reviewer avoids 240 V and stays on 3–12 V circuits

Best for: A lighting or fan join on flexible cable up to 2.5 mm², where you want a lever you can open again.

Less suitable: A circuit that needs a printed current, a consumer unit, or a join where the piece count has to match the title exactly.

Common questions

Can the lever be reused?

The listing describes the lever as reusable. Strip 9–10 mm, lift the orange clip to 90 degrees, insert the wire and close it.

How many ways can they clip into?

The listing says the SPL-1 levers clip together into 2, 3, 4 or 6-way.

What is the flexible-cable limit?

The bullet says flexible cable is 0.08–2.5 mm². The title also says 18–22 AWG. Listed voltage is 250 V and listed current is not stated.

ANVINKU 65 cable lugs

Rank 5

ANVINKU 65 cable lugs

Our view

ANVINKU lists 65 tinned copper lugs from SC6 to SC25, with M6 and M8 in the type codes, at £7.79, and the spec line says 12 V DC. The first 50 United Kingdom reviews, from 474 ratings at 4.6 stars, praise a thick feel and a snug crimp on battery, inverter, camper and solar cables when a proper tool is used, including a rally car and a motorhome inverter feed. Several of those reviews describe a 30-piece or 140-piece pack, so they are not a clean report of this 65-piece title. The stud field says 6 mm only while the type codes include M8, heat-shrink is not in the bullet, and one reviewer expected heat-shrink and received slide-on sleeves. Pliers are called a hobby finish, rough edges needed filing, and one person said the wires came out. It is a lower-priced 12 V lug option than the 130-piece Gorffy box if you confirm the count and the hole before you crimp.

Pros

  • 65 lugs from 6 mm² to 25 mm² at £7.79
  • 4.6 from 474 reviews, first 50 marked United Kingdom
  • UK reviews say the tinned copper feels thick and crimps snug with a proper tool
  • Reviews mention battery, inverter, camper and solar cables

Cons

  • Some reviews describe a 30-piece or 140-piece pack
  • The stud field says 6 mm only, while the type codes include M8
  • Covers described as slide-on sleeves, not heat-shrink
  • Pliers leave a hobby finish, and one report says wires pulled out

Best for: A 12 V battery or inverter lead when you will check that the parcel is the 65-piece mix.

Less suitable: Mains wiring, a job that needs heat-shrink in the box, or a crimp closed with ordinary pliers.

Heat-shrink is not in the bullet. One review says the covers are slide-on sleeves.

Gorffy 300 insulated crimps

Rank 6

Gorffy 300 insulated crimps

Our view

Gorffy's 300-piece insulated assortment is £7.29 and covers red 0.5–1.5 mm², blue 1.5–2.5 mm² and yellow from 2.5 mm² to 6.0 mm², in 17 types of ring, fork and spade. Across the first 50 United Kingdom reviews, from a listing total of 2,780 at 4.5 stars, people keep it as stock for car, van and motorbike jobs and say a matched crimp holds. The contact is tin-plated brass, not copper, and the listed voltage is 120 V, with no current figure and no tool in the box. The same reviews call the male and female spade flimsy, with a bump that does little to hold, and they say the metal feels thinner than other kits. The box is cramped and spills because it is overfilled, and the PVC sleeves do not slip off if you also wanted to solder. At the lowest price in this set with a four-figure review count, it is the best value for vehicle crimps if you already own a red, blue and yellow ratchet and you treat the spades as the weak part.

Pros

  • 300 pieces in 17 types at £7.29
  • 4.5 from 2,780 reviews, first 50 marked United Kingdom
  • UK reviews say a matched crimp holds on car, van and motorbike wiring
  • Colour bands are printed, including yellow from 2.5 mm²

Cons

  • Tin-plated brass, and the listed voltage is 120 V
  • Spade push-fits called flimsy, with little help from the latch bump
  • Box overfilled and easy to spill, and no crimp tool is included
  • Sleeves will not slip off if you also want to solder

Best for: Spare insulated rings and forks for vehicle wiring when you already have a ratchet.

Less suitable: A job that needs a 230 V listing, a copper contact, or a latching spade you can trust.

Bolatus 300 insulated crimps

Rank 7

Bolatus 300 insulated crimps

Our view

Bolatus packs 300 insulated crimps at £8.99, with red 0.5–1.5 mm², blue 1.5–2.5 mm² and yellow 4–6 mm², in ring, fork, spade and butt shapes. The first 50 United Kingdom reviews, from 1,034 ratings at 4.5 stars, praise the mix for car, motorbike and motorhome wiring, and several say the bullet connectors crimp and hold. The contact field says tinned copper and the voltage line says 230 V AC, which is the insulated kit in this set that prints a mains figure, though the current is still blank and no tool is included. The same sample calls the metal flimsy and easy to bend, and one yellow ring let the wire pull out because the barrel had little surface. The box is smaller than some buyers expected and spills if you open it upside down. It is the clearer voltage listing of the two 300-piece tubs if you accept thin metal and buy the ratchet separately.

Pros

  • 300 pieces in ring, fork, spade and butt, at £8.99
  • Tinned copper, with yellow listed as 4–6 mm²
  • 4.5 from 1,034 reviews, first 50 marked United Kingdom
  • Listed voltage is 230 V AC

Cons

  • No crimp tool, and reviews say you need one
  • Thin metal, and one yellow ring let the wire pull out
  • The box spills if it is opened upside down
  • Listed current is not on the page

Best for: Insulated rings, forks and butts when you want tinned copper and a 230 V AC line on the listing.

Less suitable: A heavy battery cable, or a crimp you plan to close with ordinary pliers.

flintronic 1,500 ferrules

Rank 8

flintronic 1,500 ferrules

Our view

The flintronic ferrule box is 1,500 bootlace ferrules from 0.5 mm² to 10 mm² at £8.99, and it contains no crimp tool. Of 33 captured review blocks, 21 are marked United Kingdom, against a listing total of 181 at 4.5 stars, and those reviews say a matched size crimps and holds. One reviewer used them on RCBO cable tails and said they stayed on, which is a single comment, not a reason to open a consumer unit yourself. The bullets disagree on the barrel: one says tinned copper and another says tin-plated brass with a copper tube. There is no colour-to-size table, the standard field says CE with no BS number, and voltage and current are blank. The box is criticised as flimsy, and opening it label-side up dumps the pieces. One reviewer could not crimp them onto any wire, and another saw the plastic collar break and the metal barrel split even with a proper ferrule tool and the matching size. It is a refill of sizes if you already own a square-jaw tool and you can sort an unmarked colour code.

Pros

  • 1,500 ferrules from 0.5 mm² to 10 mm² at £8.99
  • 4.5 from 181 reviews, with 21 of 33 captured blocks marked United Kingdom
  • UK reviews say a matched size holds
  • A wide size range in one box

Cons

  • No crimp tool, and the barrel-metal bullets conflict
  • No colour-to-size table on the page
  • The box spills if it is opened label-side up
  • A collar or barrel can split under a crimp

Best for: A refill of bootlace sizes when you already have a four-jaw ferrule tool.

Less suitable: A first ferrule kit, a red-blue-yellow crimp, or work inside a consumer unit.

Gorffy 130 tinned copper lugs

Rank 9

Gorffy 130 tinned copper lugs

∼£14

Our view

Gorffy's second listing is 130 tinned copper tube lugs from 6 mm² to 25 mm² with M6 and M8 holes, at £13.98, and they are non-insulated. The first 50 United Kingdom reviews, from 734 ratings at 4.4 stars, describe a useful spread for campervan and workshop cables, and they look neat once you add your own heat-shrink. The listed maximum is 12 V DC, the standard field says VDE with no BS number, and no current is printed. Heat-shrink is not in the bullet and no crimp tool is included. Reviewers call the metal a bit flimsy next to heavier lugs, and one 16 mm² cable was put into a 10 mm² lug and slid off after crimping. The piece counts on the page add up to the title's 130, which is clearer than the other lug packs here. It suits a 12 V camper or battery lead if you match the barrel to the cable and close it in a lug die.

Pros

  • 130 tinned copper lugs, 6–25 mm², M6 and M8, at £13.98
  • 4.4 from 734 reviews, first 50 marked United Kingdom
  • UK reviews name campervan and workshop cables, neat once heat-shrink is added
  • The printed piece counts add up to 130

Cons

  • Listed maximum is 12 V DC, not mains
  • Non-insulated, and heat-shrink is not in the box
  • No crimp tool, and one undersized lug slid off a 16 mm² cable
  • Metal called thinner than heavier lugs

Best for: A 12 V camper or battery cable from 6 mm² to 25 mm² when you already own a lug crimper and heat-shrink.

Less suitable: 230 V fixed wiring, or a 35 mm² lead that needs an SC35-10 lug.

AivaToba bootlace ferrule kit

Rank 10

AivaToba bootlace ferrule kit

∼£18

Our view

AivaToba's bootlace kit is £17.99 and puts 1,340 ferrules, including two types of twin ferrule, beside a self-adjusting four-jaw ratchet, model HSC8-6-4A, that holds the cycle until it finishes. The bullet says 0.25–10 mm² and the size field says 0.5–10 mm². Nine captured United Kingdom reviews, from 21 ratings at 4.4 stars, praise the even square crimp and the twin sleeves for two wires, including campervan solar and 12 V work and some lighting wiring. Contact metal and voltage are not stated, and there is no colour-to-size table on the page. The box is full, and one review says it spills if you drop it. Reviewers call it good enough for home and hobby use and not the tool they would use to make a living, at a price above a ferrules-only box. It is the ferrule option in this set when you do not already own a square jaw, if you sort the collar colours yourself.

Pros

  • Four-jaw ratchet HSC8-6-4A with a forced cycle, at £17.99
  • 1,340 ferrules, including two types of twin ferrule
  • UK reviews praise an even crimp and sleeves for two wires
  • The bullet range starts at 0.25 mm²

Cons

  • Only 21 reviews sit behind the 4.4 star line
  • No colour-to-size table is printed
  • The size field says 0.5–10 mm² while the bullet says 0.25–10 mm²
  • The box spills if it is dropped, and the contact metal is not stated

Best for: Flexible cable into a screw clamp when you need both the ferrules and a square jaw.

Less suitable: Insulated ring terminals, or a daily professional driver who already owns a ferrule tool.

InYoHui 10 SC35-10 lugs

Rank 11

InYoHui 10 SC35-10 lugs

Our view

InYoHui sells 10 SC35-10 tinned copper lugs at £6.99, each for 35 mm² cable and a 10.5 mm hole, and nothing else in the size range. The listing is 4.3 from 8 reviews, and one captured United Kingdom review says the lugs barely did the job, several popped off, and the buyer called them unsafe and pointed towards an electrical supplier. The title, highlight and unit count say 10 pieces, while the number-of-items field says 50, and Included Components says cable clips. No voltage or current is printed, no tool is included, and the bullet allows a crimp or a weld without naming a die. The standard field says ISO 9001, which is not a crimp test of this lug. It is a single-size 35 mm² ring only if you already know the stud suits a 10.5 mm hole and you are willing to judge the pack from one poor review.

Pros

  • One size only: 35 mm² cable and a 10.5 mm hole, at £6.99
  • Tinned copper is stated
  • The title and the unit count agree on 10 pieces
  • A small pack if you need only SC35-10

Cons

  • 4.3 from 8 reviews, and the one UK text says lugs popped off
  • Number of items says 50, against a title of 10
  • No voltage is printed, and no tool is included
  • Included Components says cable clips

Best for: A known 35 mm² cable on a stud that takes a 10.5 mm hole, after you have checked the current listing.

Less suitable: An assortment, a mains connection, or a buyer who needs more than one review that the crimp held.

Common questions

Is this pack only SC35-10?

Yes. Conductor size is 35 mm² and the hole is 10.5 mm. It is not an assortment.

How does the bullet say to fit them?

Crimp with standard tools, or weld, then bolt. No tool is in the box.

Is a voltage printed?

No voltage is on the page. One captured UK review is on the listing, and the listing total is 8.

AivaToba insulated crimp kit

Rank 12

AivaToba insulated crimp kit

∼£24

Our view

The AivaToba HHS-30J kit is £23.99 and pairs a ratchet, with jaws marked red, blue and yellow, to 370 insulated terminals from 0.5 mm² to 6 mm², yellow running from 4.0 mm² to 6.0 mm². Ten captured United Kingdom reviews, from a listing total of 31 at 4.2 stars, say the ratchet finishes a consistent crimp with little effort, including a car head-unit install and bullet splices, and that the release works if the terminal slips before the crimp. Contact metal, voltage and current are all absent from the spec table. The Included Components line says wire-end ferrule pliers, which is a different tool family from the insulated terminals in the title, and the number of items is 371 against a title of 370. Reviewers call the kit pricey and the terminals a little thin, though the captured UK texts do not repeat a broken tool. It is the insulated ratchet in this set if you can live with an unnamed metal and a parts line that points at ferrules.

Pros

  • Ratchet with red, blue and yellow jaw marks, plus 370 terminals, at £23.99
  • UK reviews say the cycle is consistent and the handles work with gloves
  • The release works if the terminal slips before the crimp
  • A storage box is included

Cons

  • 4.2 from only 31 reviews
  • Contact metal and voltage are not in the spec table
  • Included Components says wire-end ferrule pliers
  • Terminals are called thin, and the kit is called pricey

Best for: A first insulated-terminal ratchet for vehicle spades, rings and butt splices.

Less suitable: Bootlace ferrules, or a joint that needs a named copper contact and a printed voltage.

Common questions

Is the tool a ratchet?

Yes. The jaws have colour marks for red, blue and yellow. One review says the release is easy if the terminal slips before the crimp.

Is there a storage box?

Yes. The kit is a ratchet crimper and insulated terminals in a storage box.

What does Included Components say?

How we compared

Twelve cable-terminal listings on amazon.co.uk were scored from the listing text and the captured UK review notes, not from a pull-out test or a BS 7671 certificate. The published score is the display score. A large UK review sample and a voltage printed on the spec line hold that score up. A missing current, a piece-count clash, the wrong metal for the job, or a repeated fault in the reviews brings it down. A line that says the product meets all electrical standards adds nothing. The weights below follow the buying order in the digest.

1

Family and conductor size

30%

Insulated crimp, tubular lug, bootlace ferrule, open-barrel pin or lever block, matched to the cable in mm². A red, blue and yellow crimp is not a ferrule colour code.

2

Stud, tab or clamp

15%

Ring, fork, spade, butt, lever, or a hole such as M6, M8 or the 10.5 mm hole on an SC35-10 lug. The stud has to match the terminal you are buying.

3

Metal and printed voltage

20%

Tinned copper, tin-plated brass, or nickel-plated copper, and the voltage printed on that listing. A 12 V DC field is not moved to 230 V mains. Tin is not a seal.

4

Die or tool in the box

15%

A red, blue and yellow ratchet, a square ferrule jaw, or a lug die. Ordinary pliers are not that tool. A kit only scores here when the matching tool is actually in the box.

5

Review sample and faults

20%

Star line and review count from the amazon.co.uk listing. The score drops when UK reviews repeat thin metal, a crimp that lets go, a box that spills, or when the sample is one rating.

Cable terminals buying guide

Start with the family, then the cable in mm² and the stud or clamp, then the metal and the die. Price comes after those. The notes below follow that order for these 12 amazon.co.uk listings. None of the scores is a crimp test.

What are cable terminals?

Cable terminals on this page are four families, not one ranking. Insulated crimps use a ring, fork, spade, bullet or butt. Tubular copper lugs, bootlace ferrules and lever blocks do different jobs. UK trade guides use red for about 0.5–1.5 mm², blue for 1.5–2.5 mm² and yellow for about 4–6 mm². Gorffy's 300-piece listing starts yellow at 2.5 mm². Red and blue overlap at 1.5 mm². Those colours are not the French or German ferrule codes.

Best for

  • A lighting or fan join on flexible cable up to 2.5 mm², if you can accept a lever pack whose piece count is not settled
  • Vehicle rings and forks when you already own a red, blue and yellow ratchet, and you read 120 V as 120 V
  • A 12 V camper or battery lead from 6 mm² to 25 mm² when you already own a lug die and heat-shrink

Not ideal for

  • A consumer unit, a new circuit, meter tails, aluminium, or an EV high-voltage connector
  • Anyone reading a 12 V DC lug, a 120 V line, or a single 5.0 rating as proof of a mains joint
  • A ferrule closed in a red-blue-yellow jaw, or a crimp closed with ordinary pliers

Mistakes to avoid

  1. 1

    Mixing ferrule colours with crimp colours

    Red, blue and yellow on an insulated crimp are cable-size bands, about 0.5–1.5, 1.5–2.5 and 4–6 mm². French ferrule colours are a different code, and a German code paints 1.5 mm² red. A red ferrule is not a 0.5–1.5 mm² crimp.

  2. 2

    Closing the crimp with pliers

    Insulated crimps need a red, blue and yellow ratchet. Ferrules need a square jaw. Lugs need a lug die. UK reviews on the lug packs call a pliers finish a hobby crimp, and one undersized barrel slid off a 16 mm² cable.

  3. 3

    Moving a printed voltage

    Gorffy lugs and ANVINKU list 12 V DC. Gorffy's insulated box lists 120 V. Okeno lists 250 V and also prints 600 V in a bullet. Leave each figure on that listing. Do not solder a flexible end and clamp the solder.

What to weigh up

Family, size and stud

High

Pick the family before the piece count. Insulated crimps in this set are rings, forks, spades and butts from about 0.5 mm² to 6 mm². Tubular lugs are 6–25 mm² with M6 or M8 holes, plus one 10-piece SC35-10 pack at 35 mm² and a 10.5 mm hole. Lever blocks take solid cable to 4 mm² and flexible cable only to 2.5 mm². Bootlace ferrules are a separate colour system for fine strands into a screw clamp.

Metal, voltage and die

High

The lug packs name tinned copper. Gorffy's 300 insulated crimps are tin-plated brass, listed at 120 V. Bolatus names tinned copper and 230 V AC, with current still blank. Flintronic levers list 250 V and no current. Okeno lists 250 V and 32 A, and a bullet also prints 600 V, which no captured review checks. InYoHui and TOPCZY print no voltage. Tin is not a seal, and a VDE or CE field with no BS number is not a BS 7671, BS EN IEC 60352-2 or BS EN IEC 61238 certificate.

Which option suits you?

Three typical situations, each with a recommendation from this comparison.

A lighting join you can open

You are joining lighting or fan wires on flexible cable up to 2.5 mm² and you want a lever you can open again. The flintronic pack is about £7.98. Current is not printed, and the piece count clashes.

Vehicle rings and forks

You want spare insulated crimps for car, van or motorbike wiring and you already own a red, blue and yellow ratchet. Gorffy's 300-piece box is about £7.29. The contact is tin-plated brass and the voltage line says 120 V.

Fine strands into a screw

Flexible cable into a screw clamp needs a ferrule and a square jaw, not a red-blue-yellow crimp. The AivaToba kit is about £17.99 and includes a four-jaw ratchet. Sort the collar colours yourself. Consumer-unit work stays with a competent person.

Common questions about cable terminals

Which cable terminal is the top pick in this set?
The top pick is the flintronic pack of 34 SPL-1 lever connectors, about £7.98, with 4.6 from 6,474 amazon.co.uk reviews. Solid cable is listed from 0.2 mm² to 4 mm² and flexible cable only to 2.5 mm², at 250 V. Current is not printed. The title says 34 pieces, the unit count says 50, and one review says 24, so check the count. It suits a lighting join you can open again. It is not a consumer unit. This is not a lab test.
Which listing is the best value?
The best value is Gorffy's 300 insulated crimps at about £7.29, with 4.5 from 2,780 reviews. Red is 0.5–1.5 mm², blue is 1.5–2.5 mm², and yellow on this listing starts at 2.5 mm². The contact is tin-plated brass and the voltage line says 120 V. UK reviews call the spades flimsy. It suits vehicle rings and forks if you already own a red, blue and yellow ratchet. It is the wrong box if you need a 230 V line or a copper contact.
Are bootlace ferrules compulsory on every cable?
No. Regulation 526.9 of BS 7671 requires a suitable terminal or end treatment for fine strands. The IET says ferrules are not compulsory on every cable, and solid twin-and-earth often does not need one. Do not solder a flexible end and then clamp the solder under the screw. A red, blue and yellow jaw is the wrong die for a ferrule. The bootlace ferrules page covers flexible cable and that regulation. Consumer-unit work stays with a competent person.
Can you use a 12 V lug on mains?
No. Read the voltage printed on that listing and leave it there. Gorffy's 130 lugs and the ANVINKU pack list 12 V DC. Gorffy's 300 insulated crimps list 120 V. Bolatus lists 230 V AC, and the current is still blank. InYoHui and TOPCZY print no voltage. A 12 V battery or camper lead is not 230 V fixed wiring. UK mains are 230 V. None of these boxes is a BS 7671 certificate.
What crimp tool do these terminals need?
Match the die to the family. Insulated red, blue and yellow crimps need that colour ratchet, not pliers. Bootlace ferrules need a square jaw, such as the four-jaw ratchet in the AivaToba ferrule kit. Tubular lugs need a lug die. The AivaToba insulated kit and the QLOUNI pin kit include a crimper. QLOUNI is not universal and excludes EV high-voltage pins. Ordinary pliers are not the tool these terminals are made for.
Should you choose a ring or a fork?
A ring stays on the stud if the nut loosens. A fork slides off without taking the nut off, which is faster and easier to lose. The insulated boxes in this set include both shapes. The hole still has to match the stud: M6, M8, or the 10.5 mm hole on an SC35-10 lug. Colour on a crimp tells you the cable size, not whether the shape is a ring or a fork. Confirm the stud before you crimp.
When should you call a competent person?
Call a registered electrical competent person for a consumer unit, a new circuit, a special location, meter tails, aluminium conductors, an overheated joint, or an EV high-voltage connector. Part P of the Building Regulations 2010 makes some of that work notifiable in England. Fixed wiring is for a competent person. One review that mentions RCBO tails is not a reason to open a consumer unit yourself.
Why do the piece counts disagree?
Several titles do not match another field on the same amazon.co.uk page. The flintronic levers say 34, and the unit count says 50. TOPCZY's title says 100 and a bullet says 200 including heat-shrink. InYoHui's title says 10 and the number of items says 50. QLOUNI says 970 and 969. TOPCZY's 5.0 is one rating with no review text. QLOUNI's 4.8 is 29 ratings, with two UK reviews captured. Do not treat those stars as a large sample.

Our verdict

In this set of 12 amazon.co.uk listings, the top pick is the flintronic pack of 34 SPL-1 lever connectors at about £7.98. The display score is 91, from 4.6 across 6,474 reviews, after a missing current and a piece-count clash. It is for a reusable lighting join inside the printed sizes. The best value is Gorffy's 300 insulated crimps at about £7.29. The display score is 86, from 4.5 across 2,780 reviews, after tin-plated brass, a 120 V line and flimsy spades. It suits vehicle crimps if you already own the ratchet. Neither score is a lab test, and neither listing is a BS 7671 certificate.
