Home and hobby, M4 to M6
You are fitting one bracket or repairing furniture, and the insert stays at M6 or below. The 8 inch eSynic lists M3 to M6 at about £24.02, with 4.4 from 1,247 reviews. UK notes say M6 needs a strong grip.
Rivet nut pliers compared
The best rivet nut pliers, compared.
Top pick: eSynic 10 inch rivet nut tool, M3–M8 Best value: eSynic 8 inch rivet nut tool, M3–M6 – Lowest shelf price among listings with more than 1,000 ratings and a mandrel list that does not contradict itself, about £24.02. Updated October 2026.
A rivet nut pliers set pulls a threaded mandrel so a rivet nut collapses behind sheet or tube and leaves a machine-screw thread from one side only. The mandrel has to match the thread you will set. Titles that say M3 to sometimes stop at, and the ratchet here starts at. An 8 inch tool fits tighter spaces and stops at. Grip range belongs to the nut, not to the pliers. Use the [rivet nut pliers buying guide](/hub/pliers/rivet-nut-pliers/sub/rivet-nut-pliers-buying-guide) for arm length and the real mandrel list. On amazon.co.uk the usual buy is a 12 to 14 inch lever kit with metric mandrels and a box of nuts, for vans, brackets, and thin steel or aluminium. What decides the kit is the mandrel that matches the thread, enough handle for the largest nut, and a nut whose grip range covers the panel.

The best rivet nut pliers in detail
Our view
The eSynic 10 inch kit, model ESY437, lists five mandrels from M3 to M8 and 470 nuts, split as 140 M3, 150 M4, 100 M5, 60 M6 and 20 M8, at £24.67. The star line is 4.8 from 10 ratings, and one review text is marked United Kingdom, which is too small a sample to treat as a workshop record. The page was first listed on 24 June 2026, so it is new beside the 8 inch eSynic that has been on sale since August 2020. The listing describes alloy steel with drop-forged carbon steel upper handles, a storage case, and a weight of 1.86 kg. M10 and M12 are not in the included-components line. A 4.8 on ten ratings can sit above a 4.4 on more than a thousand and still tell you less about the next mandrel. Take it only if you have checked the live offer and you can return a kit whose reviews have not had time to accumulate.
Pros
- Mandrels M3 to M8 named in one included-components line
- 470 nuts with a printed split, in a storage case
- 10 inch lever at £24.67 and 1.86 kg
- Drop-forged carbon steel upper handles claimed on the listing
Cons
- 4.8 from 10 ratings, with one UK review text
- First listed 24 June 2026, so the review file is still short
- No M10 or M12 mandrel
- Alloy and forging lines are seller claims, not a measured pull
Best for: An M8-capped kit only after you accept a ten-rating file and check the live contents.
Less suitable: Anyone who needs a review history, or a job that calls for M10 or M12.

Common questions
Does the 10 inch kit include M10 and M12?
No. The listing’s included-components line stops at five mandrels: M3, M4, M5, M6, and M8.
How many rivet nuts are in the box?
The listing says 470: 140 M3, 150 M4, 100 M5, 60 M6, and 20 M8, in a storage case.
Is the 4.8 score from a large UK sample?
The listing star line is 4.8 from 10 ratings. One review text is marked United Kingdom.
Our view
The LIBRATON 919014 is the only ratchet in this set, at £65.99 and 2.9 kg, with mandrels M5, M6, M8, M10 and M12, five nut heads, 50 nuts and a rugged case. Across 404 amazon.co.uk reviews the score is 4.5. UK comments compare the effort with long-lever tools, and they also include a report that an M8 steel insert did not collapse, so “compatible with stainless” on the bullets is not a measured pull. M3 and M4 are not in the mandrel list, which rules the tool out for furniture screws in those sizes. The body is a ratchet with a quick-change mandrel, not a 14 inch lever, so it is the option when a long tool’s handles will not swing inside a pillar or a cabinet. It is not the trade ratchet listed elsewhere at about £163 including VAT. Choose it when the insert is M5 or larger and the space will not take a long arc. Leave it for M3, M4, or a steel insert you have not proved on scrap.
Pros
- Ratchet body for restricted swing, at 2.9 kg with a rugged case
- Mandrels M5, M6, M8, M10 and M12, the large end of the range
- 4.5 from 404 reviews
- 50 nuts, ten of each of five sizes, plus five nut heads
Cons
- No M3 or M4 mandrel
- £65.99, the highest price in this set
- One UK review says an M8 steel insert did not collapse
- 50 nuts is a small starter pack beside the lever kits
Best for: M5 to M12 inserts in a pillar or cabinet where a long lever cannot open.
Less suitable: M3 and M4 work, open-bench M6 where a cheaper lever fits, or unproved steel nuts.

Common questions
Is this a long-lever plier?
No. The listing describes a ratchet mechanism with a quick-change mandrel. UK reviews compare the effort with long-lever tools.
Does it include M3 and M4?
The listing’s five mandrels are M5, M6, M8, M10, and M12. M3 and M4 are not in that list.
Does the listing guarantee steel M8 inserts?
The bullets say the tool is compatible with aluminium and stainless steel nuts. A UK review says an M8 steel insert did not collapse. There is no measured pulling force.
Our view
The Proster 14 inch tool lists six interchangeable mandrels from M3 to M10, 150 nuts and a carrying case, at £35.99. The star line is 4.4 from 2,132 ratings, the largest review file in this comparison, which is why it leads the score after a deduction for durability complaints. UK review texts describe a head shearing or a thread stripping within a few nuts, so the average is not a test that the mandrel lasts. M12 is not in the bullet list. The listing says you can change mandrels and nozzles by hand, without a measured change time, and the alloy-steel and dual-hinge lines are seller claims with no stated weight. The TPU rubber-coated handles are not described as electrically insulated. For repeated M6 to M10 work where the handles can open and you want the deepest amazon.co.uk review history in this set, it is the top pick on that criterion. It is the wrong box if the drawing calls for M12, or if you need a written sample with no early-failure comments.
Pros
- Mandrels M3, M4, M5, M6, M8 and M10 in one bullet list
- 4.4 from 2,132 ratings, the largest file in this set
- Carrying case and 150 nuts named
- Hand change of mandrels and nozzles claimed on the listing
Cons
- UK texts describe a sheared head or a stripped thread within a few nuts
- M12 is not listed
- Weight is not stated
- Handles are not described as insulated, and the alloy line is untested here
Best for: Repeated M6 to M10 work where a 14 inch lever can open and you want the largest review file.
Less suitable: An M12 insert, a tight space with no handle swing, or a buyer who reads 4.4 as proof the mandrel lasts.

Common questions
What is the largest mandrel on the Proster listing?
The bullets list six interchangeable mandrels: M3, M4, M5, M6, M8, and M10. M12 is not listed.
Does a 4.4 average mean the mandrel lasts?
The star line is 4.4 from 2,132 ratings. UK review texts also describe a head shearing or a thread stripping within a few nuts. The average is not a durability test.
Can you change the mandrel without a spanner?
The listing says you can change mandrels and nozzles by hand. It does not show a measured change time.
Our view
Across 1,247 amazon.co.uk reviews the eSynic 8 inch tool sits at 4.4 stars and £24.02, with mandrels listed as M3, M4, M5 and M6 plus 100 nuts in a carrying box. That cap is the job: the listing does not include M8, M10 or M12, so a bracket that needs a larger insert is a different purchase. UK notes on this short lever say M6 needs a strong grip, which fits an 8 inch tool at 1.3 kg rather than a 14 inch arm. The TPR handles have a lock for storage and are not described as electrically insulated. A 4.4 average from a four-figure sample tells you how the kit is received, and it does not count how many nuts one mandrel survives. At this price, with a parts list that does not contradict itself, it is the best value in the set when the work stays at M6 or below. If the next hole is for M8, this box does not contain the mandrel.
Pros
- Mandrels M3, M4, M5 and M6 in one list, with no second conflicting size line
- £24.02 and 4.4 from 1,247 amazon.co.uk reviews
- Carrying box and a handle lock named on the listing
- 8 inch and 1.3 kg, shorter than the 14 inch levers in this set
Cons
- No M8, M10 or M12 mandrel on the listing
- UK notes say M6 needs a strong grip
- TPR handles are not described as insulated
- 100 nuts are a starter pack, and the listing does not call them steel
Best for: Furniture and bracket jobs that stay at M3–M6, where an 8 inch lever can open.
Less suitable: M8 and larger, or a tight M6 in steel where the short lever already draws grip complaints.

Common questions
What thread sizes does this 8 inch tool list?
The amazon.co.uk listing lists interchangeable mandrels M3, M4, M5, and M6, plus 100 rivet nuts. It does not list M8, M10, or M12.
Does it come with a case?
The listing says a portable carrying box. It also mentions a handle lock that buckles the handles when the tool is stored.
Are the handles described as electrically insulated?
The listing says TPR handles. It does not describe them as insulated, and it does not name a live-working standard.
Our view
The HARDELL 14 inch kit, model A41-HDRG1402-1, is £33.99 with 4.4 from 359 reviews and a rank of 3 in Riveters on the listing checked here. The title lists M3, M4, M5, M6, M8 and M10 plus three inch sizes, and 164 pieces. A bullet on the same amazon.co.uk page lists six mandrels — M6, M8, M10, 1/4-20, 5/16-18 and 3/8-16 — and 80 rivet nuts. Those lines cannot both be the contents of one box, and the listing does not resolve them. The tool weighs 2.17 kg, with straight handles in a soft rubber wrap and a rugged carrying case. Inch threads are unusual in this otherwise metric set, and they are only useful if the bullet, rather than the title, is what arrives. No sheet-thickness limit is stated. Buy it only after you can check the mandrels against the job, and send it back if M3 to M5 are missing when the title promised them.
Pros
- 14 inch lever at £33.99 with a rugged carrying case
- 4.4 from 359 reviews, and rank 3 in Riveters on this listing
- Inch sizes 1/4-20, 5/16-18 and 3/8-16 are at least claimed
- Weight stated at 2.17 kg
Cons
- Title and a bullet disagree on which mandrels are included
- 164 pieces in the title and 80 nuts in a bullet
- No sheet-thickness limit on the listing
- You cannot know the small metric mandrels are present until the box arrives
Best for: A buyer who can open the case on arrival and return it if the mandrels do not match the job.
Less suitable: Anyone who needs M3 or M12 confirmed before paying, or a parts list that says one thing.

Common questions
Which mandrels are actually in the HARDELL kit?
The title lists M3, M4, M5, M6, M8, M10 and three inch sizes. A bullet lists six mandrels: M6, M8, M10, 1/4-20, 5/16-18, and 3/8-16. The listing does not resolve that.
How many rivet nuts does the listing claim?
The title says 164 pieces. A bullet says 80 rivet nuts. Both figures are on the same amazon.co.uk listing.
Does the listing state a sheet-thickness limit?
No. The bullets name auto panels and HVAC ducts, and they do not give a maximum thickness in millimetres.
Our view
The AMTOVL AVL013 is a 12 inch lever at £40.99 and about 2 kg, with mandrels M3, M4, M5, M6, M8 and M10 in a carry case, and M12 is not among them. One bullet says 125 nuts, split as 40 M3, 30 M4, 20 M5, 20 M6, 10 M8 and 5 M10, while a later bullet says 120, so the count on the listing is not settled. The star line is 4.4 from 69 ratings, and a claim that the 12 inch arm saves 40% effort has no measured force behind it. Chrome vanadium mandrels and a 45 carbon steel arm are listing materials, not a lab result. At £40.99 it costs more than the 14 inch Proster and the 35 cm AojSup, with a shorter arm, a smaller review file and a parts list that disagrees with itself. Consider it if the live offer’s nut count has been corrected and M10 is your ceiling. Skip it while 125 and 120 are both printed.
Pros
- Six mandrels from M3 to M10, with M12 correctly absent
- Carry case and a wrench named
- 12 inch and about 2 kg, so length and weight are stated
- 4.4 from 69 reviews, a mid-size file
Cons
- 125 nuts in one bullet and 120 in another
- £40.99, above longer levers in this set that list a single nut count
- The 40% effort line is unmeasured
- 69 ratings will not show a slow mandrel failure
Best for: An M10 job only after the live listing shows one nut count.
Less suitable: M12, or a buyer comparing price with the longer levers that cost less in this comparison.

Common questions
How many nuts does the AMTOVL listing include?
One bullet says 125 nuts, with a split from M3 to M10. A later bullet says 120 nuts. Both lines are on the same amazon.co.uk listing.
Does it include M12?
No. The six mandrels are M3, M4, M5, M6, M8, and M10.
Is the 40% effort claim measured?
The listing says the 12 inch arm saves 40% effort. There is no measured force.
Our view
The AojSup A-06 is the long lever in this set whose listing names seven metric mandrels from M3 to M12, with 110 nuts, a wrench and a transparent storage box, at £29.99. Across 250 amazon.co.uk reviews the score is 4.2, below the 4.4 tools that stop at M10. The length is 35 cm and the weight is 1.82 kg, so the handles need room to open even though a bullet claims about 30% less effort than a conventional rivet nut pliers. That percentage is a seller line, and there is no measured force. The accessories sit in a transparent box, which the listing does not call a blow-moulded case. Carbon steel and electrophoretic painting are listing claims, not a hardness test. If the requirement is an M12 mandrel on the bullet list and you can swing 35 cm, this is the lever that states that range in one place. Leave it if you want the largest review file, or a ratchet for a door pillar.
Pros
- Seven mandrels, M3 through M12, in one bullet list
- £29.99, below the 14 inch M10 levers in this set
- 110 nuts, a wrench and instructions named in the box
- 35 cm and 1.82 kg, so the reach is stated
Cons
- 4.2 from 250 reviews, the lowest large-file star line among the long levers
- About 30% less effort is a listing claim with no measured force
- Transparent storage box, not described as a hard case
- 35 cm handles still need a clear arc
Best for: A bench or an open panel where you need M12 on the bullet list and the handles can open.
Less suitable: A tight pillar, a buyer who wants thousands of reviews, or anyone treating the 30% line as a test.

Common questions
Does this kit list an M12 mandrel?
Yes. The listing says seven metric mandrels from M3 to M12, with 110 nuts and a multifunctional wrench.
Does it come in a hard case?
The listing says the accessories sit in a transparent storage box. It does not say blow-moulded case.
Does the listing prove a 30% effort saving?
The bullet claims about 30% less effort than a conventional rivet nut pliers. There is no measured force.
Our view
The INCIKITI 14 inch tool lists six mandrels, M3 through M10, with 150 nuts, a spanner and a rugged carry case, at £32.29. The star line is 4.0 from 34 ratings, and 22 of the review texts are marked United Kingdom, so the sample is small and it is at least a UK sample. M12 is not in that bullet list, which matters if a similar title has trained you to expect it. Quick-change without extra tools is claimed without a timed change, and the weight is not stated. Chrome steel mandrels and a 45 carbon steel arm with a double compound hinge are seller descriptions, not a measured result. A 4.0 on 34 ratings is the weakest star line in this set, and that sample will not show a failure that appears after a few dozen nuts. Use it when the case and the M10 cap match the job and you accept a thin review file. Do not read a 14 inch arm as proof that M12 is in the box.
Pros
- Six mandrels, M3 to M10, in one bullet list
- Rugged carry case, spanner and 150 nuts named
- 14 inch arm with a double compound hinge claimed
- 22 of the review texts are marked United Kingdom
Cons
- 4.0 from 34 ratings, a thin sample
- M12 is not in the bullet list
- Weight is not stated
- Quick-change is claimed without a measured change time
Best for: An M10 ceiling where you want a 14 inch lever and a case, and you can live with 34 ratings.
Less suitable: M12 work, or a buyer who wants a review file large enough to show early mandrel failures.

Rivet nut pliers buying guide
Start with the largest thread you will set, then with whether a long lever can open. Nut material and grip range come after the mandrel is actually in the box. The notes below follow that order for these eight listings.
What is a rivet nut pliers?
A rivet nut pliers set pulls a threaded mandrel so a rivet nut collapses behind sheet or tube and leaves a machine-screw thread from one side only. It is not a pop rivet gun. On amazon.co.uk the usual buy is a 12 to 14 inch lever kit with metric mandrels and a box of nuts, for vans, brackets, and thin steel or aluminium. What decides the kit is the mandrel that matches the thread, enough handle for the largest nut, and a nut whose grip range covers the panel.
Best for
- Furniture and bracket jobs that stay at M4 to M6
- Van and box-section work where handle swing is the limit
- Repeated M6 to M10 work where a spare mandrel matters
Not ideal for
- A pop rivet, which needs a rivet gun rather than a threaded insert
- A structural or safety-critical joint, or a panel next to fuel, airbags or unidentified wiring
- Anyone who treats the title’s size range as the contents of the box
Mistakes to avoid
- 1
Trusting the title over the bullets
Titles that say M3 to M12 sometimes stop at M10. HARDELL’s title and a bullet disagree on mandrels and on 164 pieces versus 80 nuts. Read the bullet list, then check the mandrels when the box arrives.
- 2
Buying a pop rivet gun
A rivet gun sets a blind rivet. It does not leave a machine-screw thread. Drill-hex spinners and loose nut packs are not pliers either. The tool has to pull a threaded mandrel.
- 3
Treating the kit nuts as steel
The nuts in the case are often a starter pack, and reviewers call some of them soft aluminium. Steel and stainless need more pull. Grip range belongs to the nut. Do not use those aluminium nuts for a high-torque bracket.
What to weigh up
Largest thread and the parts list
HighThe first check is the largest thread you will set, and whether that mandrel is in the bullet list. Titles that say M3 to M12 sometimes stop at M10. In this set, INCIKITI, Proster and AMTOVL list M3 to M10. The eSynic 10 inch stops at M8. The eSynic 8 inch stops at M6. The LIBRATON ratchet starts at M5 and runs to M12, so M3 and M4 are not in that box. The AojSup is the lever whose bullets name seven metric mandrels from M3 to M12. HARDELL is the listing that does not say one thing.
Mechanism, reach and the nut
HighA long lever needs room to open. The 14 inch tools and the AojSup at 35 cm are the open-bench option. The 8 inch eSynic fits a tighter space and is harder at M6, which matches UK notes that M6 needs a strong grip on that short lever. The LIBRATON ratchet, about £65.99 and 2.9 kg, is the restricted-access option from M5 to M12. It is not a 14 inch lever, and it is not the trade ratchet listed at £163.45 including VAT. Nut material and grip range come next.
Which option suits you?
Three typical situations, each with a recommendation from this comparison.

You are working in box section or a door pillar, where a 14 inch lever cannot open. The LIBRATON ratchet lists M5 to M12 at about £65.99. It does not include M3 or M4, and one UK review says an M8 steel insert did not collapse.
Repeated M6 to M10
You set M6 to M10 often enough that a spare mandrel matters more than the nut count in the case, and the handles can open. The Proster lists M3 to M10 and has the largest review file here, 4.4 from 2,132, at about £35.99.
Common questions about rivet nut pliers
Which rivet nut pliers are the top pick in this set?
The top pick is the Proster 14 inch rivet nut tool, about £35.99, with mandrels listed as M3, M4, M5, M6, M8 and M10. amazon.co.uk shows 4.4 from 2,132 reviews, the largest file here, after a deduction for UK texts that describe a sheared head or a stripped thread within a few nuts. M12 is not listed. The score uses those listing facts. It is not a lab test, and it does not prove the mandrel lasts.
How much do rivet nut pliers cost on amazon.co.uk?
On these eight shelves, checked on 15 October 2026, prices run from about £24.02 to about £65.99. The two eSynic levers are about £24.02 and £24.67. The mid band is the AojSup at about £29.99, the INCIKITI at about £32.29, the HARDELL at about £33.99, the Proster at about £35.99 and the AMTOVL at about £40.99. The LIBRATON ratchet is about £65.99. A trade ratchet listed elsewhere at £163.45 including VAT is not this tool.
What should you check on the listing before you buy?
Check the largest thread you will set against the bullet list, not only the title. INCIKITI, Proster and AMTOVL stop at M10. The LIBRATON ratchet starts at M5. HARDELL’s title and a bullet disagree on mandrels and on whether the box holds 164 pieces or 80 nuts. Then check that the handles can open, and that the nut’s grip range covers the panel. The nuts in the case are often a starter pack.
When is a ratchet better than a long lever?
Choose a long lever when the handles can open and you want the lower price. The Proster is the top pick for repeated M6 to M10 work at about £35.99. The AojSup is the lever whose bullets include M12, at about £29.99, and it still needs a 35 cm arc. Choose the LIBRATON ratchet, about £65.99, when the insert is M5 or larger and a pillar or cabinet will not take that swing. It does not include M3 or M4.
Is a rivet nut pliers the same as a rivet gun?
No. Rivet nut pliers pull a threaded mandrel so a rivet nut collapses and leaves a machine-screw thread. A pop rivet gun sets a blind rivet that does not leave a thread you can bolt into. Buying the gun will not install the nuts in these cases. If the job is a blind rivet rather than a threaded insert, use the rivet gun comparison. Drill-hex spinners and loose nut packs are not pliers either.
Do these manual kits comply with BS EN ISO 11148-1?
No. BS EN ISO 11148-1 covers powered rivet-nut setters that use air, hydraulics or an engine. Do not treat these hand kits as compliant with it. BS EN ISO 14588 is blind-rivet terminology, not a consumer test of a £30 tool. At work in Great Britain, PUWER 1998 regulation 4 requires suitable work equipment used only for suitable operations. Wear eye protection. HSE lists projectiles as an eye hazard, and these handles are not described as electrically insulated.
When should you stop and call a professional?
Call a professional when the joint is structural or safety-critical, when the stack is outside every grip range you can buy, or when an employer has not shown anyone the tool. Stop if the panel sits next to fuel, airbags, or wiring you cannot identify. Do not guess the stroke until the mandrel strips, and do not use the kit’s aluminium nuts for a high-torque bracket. Prove the hole and the nut on scrap before you touch a finished panel.
Does a 4.4 or 4.8 star line mean the mandrel lasts?
No. Proster is 4.4 from 2,132 and still has UK reports of a sheared head or a stripped thread within a few nuts. The 10 inch eSynic is 4.8 from 10 ratings, with one review text marked United Kingdom, which is too small to treat as a workshop record. Review volume is a warning, not a winner. No listing here prints a measured pulling force, and a line that says the tool saves 30% or 40% of the effort stays a listing claim.
Our verdict
In this set of eight amazon.co.uk listings, the top pick for repeated M6 to M10 work is the Proster 14 inch tool. It lists six mandrels from M3 to M10, a case and 150 nuts, at about £35.99, with 4.4 from 2,132 reviews, after a deduction for UK texts that describe a sheared head or a stripped thread within a few nuts. M12 is not listed. The best value, when the work stays at M6 or below, is the eSynic 8 inch tool at about £24.02, with a coherent M3 to M6 list and 4.4 from 1,247 reviews. If the bullets must include M12 and the handles can open, look at the AojSup. If they cannot, look at the LIBRATON ratchet.
