The best blind rivets, compared.
Top pick: mawmuaw 60 tri-grip 4.8 x 16 mm Best value: ANVINKU 260-piece assortment – About £8.49 for six metric lengths that name an aluminium head and a steel mandrel, at 4.6 from 154, with the photograph dispute kept in view. Updated October 2026.
Blind rivets, or pop rivets, join sheet from one side. You drill a hole, insert the body, and pull the mandrel with a rivet gun until the tail forms and the stem snaps. The ordinary pattern is an open dome with an aluminium body and a steel mandrel, 2.4, 3.2, 4.0 or 4.8 mm. You choose the body length from the grip, the total thickness of the stack, including any washer. The [blind rivet grip range](/hub/screws-and-accessories/blind-rivets/sub/blind-rivets-grip-range) turns that measurement into a length. A suitable pack names the head and the metals. The nosepiece has to match the body, and the hole needs clearance over the nominal diameter. Dome heads suit ordinary sheet. A large flange or a backup washer suits soft sheet or a tired hole. Countersunk sits flush only if you countersink. Black or silver is a finish, not stainless. If the card disagrees on the metal, treat it as unresolved. These packs publish no shear figure. Wear eye protection, because the mandrel snaps. Do not use them for brakes, steering, lifting points, gas appliances or designed structural steel.

Personal buying guide
Question 1 of 2
What is the next hole?
The mawmuaw pack is 60 aluminium rivets, 4.8 x 16 mm, described as tri-grip with a three-claw tail, listed at about £7.97. The listing line is 5.0 from 5 reviews, which is too small to rank quality. The bullet calls 4.8 mm a head diameter. A review title says black while the colour field says silver. One buyer used them on a container-door hasp. The mandrel metal is not named.
Pros
Cons
Best for: You want a 4.8 x 16 mm rivet that the card says splits into three claws.
Less suitable: You want a plain dome assortment with a large review sample.
Specifications
Common questions
How does the card say these set?
The bullet says the tail expands into a three-claw lantern. You drill a hole matching the rivet diameter and pull with a rivet gun.
Is 4.8 mm the head or the body?
The bullet calls 4.8 mm the head diameter and 16 mm the head length. It also writes 4.8 x 16 mm. The card does not give a separate flange diameter.
How many reviews are there?
The Customer Reviews line is 5.0 from 5. One UK note describes a lock and hasp on a container door. One review title says the item was not delivered.
The INCLY kit is 500 countersunk rivets in 14 imperial sizes plus 500 backup washers, listed at about £21.99, with a listing line of 4.7 from 614 reviews. The washers are described as 304 stainless and as support for oversized holes. One bullet calls the rivets stainless steel, while the material line and another bullet describe aluminium rivets, so the rivet metal is not settled. One UK reviewer could not set the largest size in their existing gun. This is the only countersunk pack in the set.
Pros
Cons
Best for: You want countersunk heads and backup washers, and you will countersink the hole.
Less suitable: You want ordinary dome rivets, or you need the metal named without a stainless contradiction.
Specifications
Common questions
Are the INCLY rivets stainless?
One bullet says stainless steel pop rivets. The material field says aluminium and stainless steel, and another bullet says aluminium rivets with 304 stainless washers. The card does not settle the rivet metal as stainless.
What are the washers for?
The bullet says the countersunk backup washers give extra support when the hole is oversized. The card lists 500 washers in five sizes.
Will every size fit a small hand gun?
The card does not name a nosepiece limit. One UK review says their pop rivet gun would not set the largest rivets, so they bought a bigger gun.
The Glarks kit is 280 black aluminium-alloy rivets in eight imperial sizes plus 280 black 304 washers, listed at about £10.99. The listing line is 4.7 from 26 reviews, a small sample. UK lines mention value and the size mix. The mandrel metal is not named, and there is no grip range. The washers are the reason to pick it over a plain dome box of a similar price.
Pros
Cons
Best for: You want black rivets and backup washers for mixed imperial sizes.
Less suitable: You want a large review sample or a metric grip table.
Specifications
Common questions
How many rivets and washers are in the Glarks kit?
The bullet says 280 black rivets in eight sizes and 280 black backup washers in three sizes, in a plastic box.
What are the rivets made of?
The bullet says aluminium alloy for the rivets and 304 stainless for the washers. The mandrel metal is not named.
How many reviews are on the card?
The Customer Reviews line is 4.7 from 26. The UK texts on the card are short and positive, and that sample is small.
The KLRStec box is 500 dome-head open rivets, aluminium body and steel mandrel, 125 each of 2.4, 3.2, 4.0 and 4.8 mm, listed at about £19.99. Lengths are 6–14 mm with a grip claim of about 1–10 mm, and the card names a labelled compartment box. The listing line is 4.6 from 920 reviews, the largest sample here, which is why it is the top pick. UK reviews describe a useful size mix and a case that stays sorted. One UK review says the body diameter varies and holes had to be re-drilled, and another says the length mix is limited. No rivet gun and no washers are in the included list.
Pros
Cons
Best for: You want a van or bench assortment of ordinary dome rivets from 2.4 to 4.8 mm and you already own a gun that covers those noses.
Less suitable: You need one length only, a large flange, a countersunk head, or washers for worn holes.
Specifications
Common questions
What sizes are in the KLRStec box?
The bullets say 125 aluminium rivets in each of 2.4, 3.2, 4.0 and 4.8 mm, 500 in total, with lengths of 6–14 mm and a grip claim of about 1–10 mm.
Does the box include a rivet gun or washers?
No. The included line is the 500 rivets and a compartment storage box. The bullets say the rivets fit hand riveters, cordless guns and drill adapters.
What do the UK reviews repeat?
The listing line is 4.6 from 920. Short UK reviews praise the size mix and the case. One review says body diameter varies and holes had to be re-drilled. Another wants more lengths.
The HAOCHEN kit is 180 rivets in six lengths, aluminium head and steel mandrel, listed at about £6.99, with a listing line of 4.6 from 241. The price is low for a mixed kit. One UK review says every diameter is one step smaller than the compartment, and another says the mandrel breaks before the body has set. Those two comments are why it is not the best value pick despite the price. Most other UK lines are short and positive.
Pros
Cons
Best for: You are buying a cheap mix and you will measure a body before you drill a run of holes.
Less suitable: You need the label to match the body, or you are about to drill a long row to the printed diameter.
Specifications
Common questions
What is in the 180-piece kit?
The bullet says 45 of 3.2 x 6 mm, 40 of 3.2 x 10 mm, 25 of 4.0 x 10 mm, 25 of 4.0 x 12 mm, 25 of 4.8 x 12 mm and 20 of 4.8 x 16 mm, aluminium head and steel mandrel.
Do the UK reviews accept the printed sizes?
Most short reviews say they do the job. One UK review says the 4.8 mm pieces are 4 mm, the 4 mm are 3.2 mm, and the 3.2 mm are 2.4 mm.
Did anyone report the mandrel?
One UK review says the rod breaks off before the rivet compresses fully. The listing line is 4.6 from 241.
The DMJJSD pack is 50 large-flange rivets at about £4.99, with a listing line of 4.6 from 179. The title says aluminium, the first bullet says stainless steel, and a later bullet says aluminium heads and a steel shank, and it also mentions stud earrings. The size string is 4.8 x 10 x 16 mm without a grip range. One UK review says the shaft is an odd size. The low price does not resolve the metal.
Pros
Cons
Best for: You are spending about £4.99 on a large flange and you will check the metal when the box arrives.
Less suitable: You need a pack that names one metal and one grip.
Specifications
Common questions
Are these stainless or aluminium?
The title says aluminium. The first bullet says stainless steel. A later bullet says aluminium heads and a steel shank. The card does not pick one.
What does 4.8 x 10 x 16 mm mean on this card?
That is the only size string. The card does not say which number is body length, flange or grip.
What do UK reviews mention?
The listing line is 4.6 from 179. One buyer wanted a bigger head. One says the shaft is an odd size. One used them on a Fiat module holder.
The ANVINKU set is 260 rivets in six stated lengths across 3.2, 4 and 4.8 mm, aluminium head and steel mandrel, listed at about £8.49. That is the lowest price in this set for a mixed metric kit that names both metals, which is why it is the best value pick. The listing line is 4.6 from 154. A UK review says the photograph overstates the count and the box catches are poor, while the rivets themselves were a steel pin and an aluminium body. No grip range and no head style are printed.
Pros
Cons
Best for: You want a cheap mixed 3.2 to 4.8 mm kit and you have checked that the count, not the photograph, is what you are buying.
Less suitable: You need a labelled grip range, washers, or a pack whose photograph matches the count.
Specifications
Common questions
Which lengths are in the 260-piece set?
The bullet says 80 of 3.2 x 6 mm, 60 of 3.2 x 10 mm, 40 of 4 x 10 mm, 40 of 4 x 12 mm, 20 of 4.8 x 12 mm and 20 of 4.8 x 16 mm.
What metal does the card name?
An aluminium head and a steel mandrel. One UK reviewer who counted the pieces describes the same pair.
What do UK reviews say about the box?
One review says the photograph shows more rivets than the stated counts, the box is larger than the contents, and the catches need force. Another box arrived broken and the rivets were jumbled. The listing line is 4.6 from 154.
This pack is 120 large-flange aluminium rivets of one size, M4.8 x 20 mm, listed at about £5.48. The listing line is 4.5 from 198. UK reviews say they set and crimped before the stem parted. The mandrel metal is not named, and there is no grip range. It suits a repeated 4.8 mm large-flange hole, not a mixed repair box.
Pros
Cons
Best for: You already know you need 4.8 x 20 mm large-flange rivets.
Less suitable: You need several diameters, a named steel mandrel, or a grip table.
Specifications
Common questions
What size is this pack?
One size only: 3/16 in x 3/4 in, also written M4.8 x 20 mm, 120 pieces, large flange, aluminium.
Is the mandrel steel?
The card says a mandrel and an aluminium rivet. It does not name the mandrel metal.
What do the UK reviews say?
The listing line is 4.5 from 198. Reviews say they set, crimped before the stem parted, and were cheap. One buyer did not need 120.
The TXXATX pack is a single size, about 4.8 x 19 mm, black large flange with a brim of about 16 mm, aluminium head and iron core, listed at about £9.49. The listing line is 4.5 from 170, and the rank line says 3 in Rivets. UK reviews include stems that do not break easily, a counted 120 against a title of 100, and one open pack that was short. The hole instruction is the diameter of the rivet, with no decimal clearance.
Pros
Cons
Best for: You want a wide black flange around 4.8 x 19 mm and you can spare a few to test the snap.
Less suitable: You need a counted 100 with a grip range, or a stem that the reviews say snaps cleanly.
Specifications
Common questions
What hole does the card tell you to drill?
The bullet says drill a hole with the diameter of the rivet, then pull with 4.8 mm pliers. It does not give a decimal drill size.
What is the flange size?
Body about 4.8 mm, length about 19 mm, brim about 16 mm, black, aluminium head and iron core.
What do UK reviews dispute?
The listing line is 4.5 from 170. One review says the stems do not break off easily. One buyer counted 120 rather than 100. One pack arrived open and short.
The Zynthor pack is 200 rivets of one size, 3.2 x 10 mm, listed at about £7.99. The title says black and the colour field says Sliver. A bullet says the mandrel is aluminium. There is no review line. The item-dimensions field is 1 x 0.32 x 0.32 cm, which does not describe 200 rivets. It is a single-size pack with an unresolved finish and mandrel.
Pros
Cons
Best for: You only need 3.2 x 10 mm and you will check colour and mandrel on arrival.
Less suitable: You want a reviewed assortment or a stated steel mandrel.
Specifications
Common questions
What size is the Zynthor pack?
200 pieces, 3.2 x 10 mm. The size field says 3.2 x 10 mm.
Are they black, and is the mandrel aluminium?
The title says black. The colour field says Sliver. A bullet says an aluminium mandrel. Those lines are not reconciled.
Is there a review line?
The card has no Customer Reviews line and no review text.
The songhua pack is 80 large-flange aluminium rivets, M4.8 x 20 mm, listed at about £6.99, with a storage box claimed in a bullet. There is no review line. The colour field says black. The weight line says 20 g and the dimensions say 2 x 0.48 x 0.48 cm, which cannot be 80 rivets of this size. The mandrel metal is not named.
Pros
Cons
Best for: You want another 4.8 x 20 mm large-flange option and you will judge the pieces, not the weight line.
Less suitable: You want a reviewed pack or a weight that matches the contents.
Specifications
Common questions
What size does the songhua card state?
80 pieces of M4.8 x 20 mm large-flange dome rivets, aluminium alloy. A bullet says a storage box is included.
Why is the weight line a problem?
The technical details say 20 g and 2 x 0.48 x 0.48 cm. That does not describe 80 rivets of 4.8 x 20 mm.
Are there reviews?
The card has no Customer Reviews line and no review text. The colour field says black. The title does not.
Eleven stored amazon.co.uk listings were scored as an editorial sort, not a laboratory test. The marks follow job match, review stars, review sample, whether the card agrees with itself, and shelf price. The top pick and the best value are the awards already on those cards. No pack is treated as certified to ISO 15977 unless the card says so. None of the cards publishes a shear load. The weights below sum to 100.
Job match
35%Head, diameters, whether a steel mandrel is named, and whether the pack is a mix or one size. A grip claim scores. A card that only prints body length does not.
Listing consistency
20%Stainless against aluminium, a black title against a different colour field, a photograph that a review says overstates the count, and a weight line that cannot be the contents.
Review stars
20%The amazon.co.uk star line on the stored card. A 5.0 from five reviews is not treated as stronger evidence than a 4.6 from several hundred.
Review sample
15%The review count on that same line. Two cards have no Customer Reviews line, so the sample mark is empty.
Shelf value
10%Price against what the card actually names. The lowest mixed metric kit that names a steel mandrel is the best value. A cheaper mix with a size dispute is not.
Choose the grip before the brand line. Measure the stack, match the nosepiece to the body, and read the metal lines until they agree. A star rating does not replace a missing mandrel or a bullet that contradicts the title.
A blind rivet, called a pop rivet in UK shops, joins two or more layers from one side. You drill, insert the body, and pull the mandrel with a rivet gun until the tail forms and the stem snaps. You do not need a hand on the back of the sheet. The ordinary trade rivet is an open dome with an aluminium body and a steel mandrel. Common body diameters are 2.4, 3.2, 4.0 and 4.8 mm, which is also the range a typical hand gun can set.
The number on the packet is the rivet length. Grip is the thickness of the stack, including a washer. A short body in a thick stack will not form a proper tail.
A UK chart following ISO 15977 uses a small clearance, such as 4.9–5.0 mm for a 4.8 mm body. Too tight and the body shaves. Too loose and the set rivet can spin.
Black or silver is a finish. Stainless has to be named, and the rest of the card has to agree. Dissimilar metals left wet can corrode.
Grip is the thickness the rivet must clamp, not the body length on the bag. Measure every layer, and add a washer if you will fit one. A published UK table for 4.8 mm aluminium and steel rivets maps a 10 mm length to about 4–7 mm of grip, 12 mm to 6–9 mm, 14 mm to 8–11 mm, 16 mm to 9–12 mm, 18 mm to 12–14 mm and 20 mm to 14–16 mm. ISO 15977 treats the minimum grip as a recommendation, not a promise that every shop pack was tested to it.
Dome is the ordinary head for sheet. A large flange, or a backup washer, spreads the load on soft plastic, fabric or a hole that has already worn. Countersunk sits flush only in a countersunk hole. If you will not cut that cone, a countersunk pack leaves a ring proud of the surface. Tri-grip bodies are sold as a tail that splits into legs, which is a different set from a plain bulb, and the card still has to say which diameter is the body. Material is the other fork.
Three typical situations, each with a recommendation from this comparison.
You want 2.4, 3.2, 4.0 and 4.8 mm dome rivets in a labelled box, and you already own a gun. The KLRStec assortment is the top pick at about £19.99, with a steel mandrel named and a grip claim of about 1–10 mm. The listing line is 4.6 from 920 reviews. One UK review says body diameter varied.
The stack is the same all the way along and you want a large flange. The HexinYigjly pack is 120 rivets of M4.8 x 20 mm at about £5.48, with 4.5 from 198 reviews that say they set. The mandrel metal is not named, and there is no grip range.
You want several metric lengths and a card that names a steel mandrel, at the lowest price in this set that does both. The ANVINKU assortment is about £8.49, 4.6 from 154. A UK review says the photograph shows more rivets than the bullet counts.
The top pick is the KLRStec 500-piece dome assortment at about £19.99. It names four diameters, an aluminium body, a steel mandrel and a grip of about 1–10 mm, and the listing line is 4.6 from 920 reviews, the largest sample here. Best value is the ANVINKU 260-piece assortment at about £8.49, the lowest price in this set for a mixed metric kit that names a steel mandrel, at 4.6 from 154. A UK review says its photograph overstates the count. The HAOCHEN kit is cheaper, and a UK review says the diameters run a size small, so the lower price is not the value pick. None of these scores is a shear test, and no card is treated as ISO 15977 certified unless it says so.
ANVINKU 260-piece assortment
About £8.49 for six metric lengths that name an aluminium head and a steel mandrel, at 4.6 from 154, with the photograph dispute kept in view.
