An angle grinder quick release nut replaces only the outer clamping nut, so you can change a disc by hand instead of with a two-pin spanner. A sound nut starts cleanly on an M14 spindle, clamps the discs you use, and still undoes after a hot cut. On a UK metric grinder the usual spindle is M14×2.0 and the disc bore is 22 mm. Many US-market machines use 5/8 in-11. Ignore catalogue lines such as “#0-80” or “M14 x 1.25”. Match the nut to the grinder diameter and to any brake or quick stop. Slim nuts leave more of a flap disc usable. Tall nuts often fail to close on a 1 mm cutting disc. You need free spindle thread, often at least 8 mm, or the nut bottoms out. Pin holes matter if it seizes. It does not replace the inner flange or the guard, and it is not a click-on disc system. Thread, diameter, brake and thickness are the checks in the [angle grinder quick release nut buying guide](/hub/tools/angle-grinder-quick-release-nut/sub/angle-grinder-quick-release-nut-buying-guide).

The best angle grinder quick release nuts in detail

Masonvex quick release nut

Rank 1

Masonvex quick release nut

Our view

Masonvex is about £7.99 for two nuts and shows 5.0 from only two amazon.co.uk reviews. Both comments are positive about fit and hand tightening. Two reviews are not a sample, so the five stars do not outrank nuts with hundreds of ratings. The listing still leaves thickness, brake behaviour, and pin-spanner fallback blank. You pay more than Uskerb’s about £3.99 two-pack without gaining a maker dimension or a review base. Check the M14 thread and the disc clamp before you rely on it, and do not read the star line as a test.

Pros

  • Two nuts at about £7.99
  • The two reviews mention fit and hand tightening
  • Listing claims a tool-free change

Cons

  • Only two amazon.co.uk reviews
  • No stated thickness, brake line, or pin holes
  • Dearer than several two-packs with more reviews

Best for: A buyer who has already confirmed M14×2.0 and will trial the disc before trusting the nut.

Less suitable: Anyone shopping on a 5.0 star line, or a grinder with a brake.

Common questions

Is this nut tool-free?

The listing claims a tool-free change. Two reviews are not a sample, so the 5.0 line is not a test.

Will it fit my spindle?

Confirm M14×2.0 on the grinder. Ignore junk Amazon template lines such as “#0-80” or “M14 x 1.25”.

Can I use it on a brake grinder?

Not stated on this listing. Do not read the two five-star comments as a brake approval.

Times Mark quick release nut

Rank 2

Times Mark quick release nut

Our view

Times Mark is listed at about £5.75 with 4.8 from only 15 amazon.co.uk reviews, so the stars are early noise rather than a settled record. The title mentions a 45 mm quick release nut, the same diameter SabreCut states for the slim GRNSCB, but this page does not state a thickness. The display row counts two nuts. Comments that exist describe quick hand changes and a solid feel for the money, with a few fit complaints on particular grinders. Fifteen ratings cannot show how often a nut rusts or refuses a thin disc. Treat the pack as a low-cost trial after you have confirmed M14×2.0, not as a substitute for a nut with a published thickness.

Pros

  • About £5.75, and the title mentions 45 mm
  • 4.8 from the 15 reviews on the capture
  • Listing claims a tool-free change

Cons

  • Only 15 reviews, so the star line is thin
  • Thickness and brake suitability are not stated
  • No pin-spanner fallback on the page

Best for: A cheap trial on a grinder you have already measured as M14×2.0.

Less suitable: Anyone choosing on stars alone, or a cutting disc you have not checked against the nut shoulder.

Milwaukee FIXTEC 4932352473

Rank 3

Milwaukee FIXTEC 4932352473

∼£14

Our view

The Milwaukee FIXTEC 4932352473 is a single folding-lever nut at about £13.79, and the amazon.co.uk line is 4.7 from 2,229 reviews, the largest file in this set. UK trade listings describe article 4932352473 for M14 spindles on grinders up to 150 mm, at about 8 mm thick, and Milwaukee excludes it from brake and quick-stop machines. Reviewers describe disc swaps in about 20 seconds on 125 mm grinders, and say a firm hand turn is enough because the spindle’s rotation keeps the nut snug. The folding lever is the grip, and the pin holes are what you use when heat or an over-tight disc beats your fingers. The same buyers call about £13.79 a lot of money for one nut, and some ask whether it belongs on a 230 mm grinder. It does not. Milwaukee’s universal FIXTEC for 115–230 mm and rapid braking is a different article, and it is not this ASIN. Keep it for a small M14 grinder without a brake, and leave a pin spanner in the case.

Pros

  • Folding lever plus pin holes for a pin spanner
  • 4.7 from 2,229 amazon.co.uk reviews
  • Stated limit of 150 mm and an explicit brake exclusion
  • About 8 mm thick, so more of a flap disc stays usable

Cons

  • About £13.79 for a single nut
  • Not for quick-stop or brake grinders
  • Not the 115–230 mm universal FIXTEC

Best for: A 115 mm or 125 mm M14 grinder without a brake, when you change discs often and want a pin-spanner fallback.

Less suitable: Quick-stop machines, 230 mm grinders, X-LOCK tools, and 5/8 in-11 spindles.

SabreCut GRNSCB SUPERLOK

Rank 4

SabreCut GRNSCB SUPERLOK

∼£11

Our view

SabreCut’s GRNSCB is the slim stainless SUPERLOK, one nut at about £10.99, and SabreCut states 45 mm across and 8.9 mm thick. The amazon.co.uk line is 4.7 from 579 reviews. UK reviewers describe fast disc changes on 115 mm and 125 mm grinders and say the lower profile leaves more of a flap disc usable. SabreCut’s instruction is to hand-tighten only, and to let the spindle’s rotation finish the clamp. Complaints cluster when the nut is still too thick for a 1 mm cutting disc, or when it fouls a flap on a very small guard. This file does not state pin-spanner holes or a brake rating, so a quick-stop grinder is a guess rather than a match. It is the branded slim nut when you mostly grind or use flap discs, and a weaker choice if every job is a paper-thin cutting wheel.

Pros

  • Stated 45 mm diameter and 8.9 mm thickness
  • 4.7 from 579 amazon.co.uk reviews
  • Hand-tighten instruction from SabreCut
  • Slimmer than the GRNSCA, so more of a flap disc stays usable

Cons

  • May still fail to close on a 1 mm cutting disc
  • No pin-spanner fallback stated
  • Brake suitability is not stated

Best for: 115 mm and 125 mm M14 grinders used mainly with grinding discs and flap discs.

Less suitable: Daily 1 mm cutting discs, and any grinder whose brake behaviour is not confirmed.

Jesiah quick release nut

Rank 5

Jesiah quick release nut

Our view

Jesiah’s two-pack is about £6.29, about £3.15 a nut, and the amazon.co.uk line is 4.6 from 55 reviews, the largest generic sample here after Fentar. Reviews describe easy hand swaps and a price that feels reasonable next to the branded singles. The same file includes warnings about durability and about rust if the nut is stored damp. Thickness, maximum grinder size, pin holes, and brake suitability are all missing from the listing, so you cannot match it to a 1 mm disc or a quick-stop machine from the page alone. It is the best value in this set when you want two spare nuts and you will check the M14 thread on arrival. It is a poor stand-in for the Milwaukee nut if you need a stated brake exclusion and pin-spanner holes.

Pros

  • About £6.29 for two nuts, about £3.15 each
  • 4.6 from 55 amazon.co.uk reviews
  • Largest generic review file after Fentar
  • Listing claims a tool-free M14 change

Cons

  • Thickness, grinder limit, and brake line are not stated
  • Rust if stored damp shows up in reviews
  • No pin-spanner fallback on the page

Best for: DIY disc changes on a known M14 grinder, when you want two spares without Milwaukee money.

Less suitable: A braking grinder, a 1 mm cutting disc you have not trial-fitted, or a daily trade nut.

SabreCut GRNSCA SUPERLOK-MAX

Rank 6

SabreCut GRNSCA SUPERLOK-MAX

∼£11

Our view

SabreCut’s GRNSCA is the taller SUPERLOK-MAX, one nut at about £10.99, stated at 46 mm and 13.5 mm. The amazon.co.uk line is 4.5 from 234 reviews. UK buyers choose it when a factory nut is too shallow to clamp a deep flap or a stripper disc. That extra height is also why reviewers say it will not close on a 1 mm cutting disc and can foul a tight 115 mm guard. Hand-tighten only still applies, and this file does not state pin holes or a brake rating. Some SabreCut reviews on braking grinders describe the nut and disc loosening as the brake bites, so height is not a safety feature. Choose it for thick abrasives on an M14 spindle, and leave it if most of your discs are thin cutters.

Pros

  • Stated 46 mm diameter and 13.5 mm thickness
  • 4.5 from 234 amazon.co.uk reviews
  • Extra reach when a factory nut is too shallow for a deep flap
  • Hand-tighten instruction from SabreCut

Cons

  • Often will not clamp a 1 mm cutting disc
  • Can foul a tight 115 mm guard
  • No stated pin holes or brake rating

Best for: Thick flap discs and stripper discs on an M14 grinder whose factory nut runs out of thread.

Less suitable: Thin cutting wheels, diamond cups that the tall nut will not sit inside, and unconfirmed brake grinders.

Rohmerique quick release nut

Rank 7

Rohmerique quick release nut

Our view

Rohmerique’s two-pack is about £6.78 with 4.5 from 21 amazon.co.uk reviews. That file is too small to treat the stars as settled. The comments that exist describe straightforward fitting and a low price, and a few mention finish or how the thread feels. Thickness, grinder limit, pin holes, and brake suitability are not stated. Over-tightening is the failure that shows up across these generic packs, and 21 reviews will not tell you how this nut behaves after a hot cut. Buy it as a duplicate spare, and do not put it on a braking grinder in place of a nut the maker has excluded or approved.

Pros

  • About £6.78 for two nuts
  • 4.5 from 21 reviews on the capture
  • Comments that exist mention straightforward fitting

Cons

  • Only 21 reviews
  • No stated thickness, brake line, or pin holes
  • Finish and thread feel draw some complaints

Best for: A second spare nut for occasional DIY swaps on a confirmed M14 spindle.

Less suitable: A quick-stop grinder, or a primary nut you cannot afford to have seize.

Uskerb quick release nut

Rank 8

Uskerb quick release nut

Our view

Uskerb is the cheapest two-pack in the set at about £3.99, with 4.3 from 18 amazon.co.uk reviews. Buyers who like it talk about a backup nut for the money. Critics mention rough threads and a short service life. With under twenty ratings, the 4.3 is not a durability record. Nothing on the page states thickness or whether the nut survives a quick-stop brake. It suits light DIY use when you already trust another nut and want a glove-box spare you can afford to throw away. It is the wrong primary nut for daily disc changes on a trade grinder.

Pros

  • About £3.99, the lowest pack price in the set
  • Two nuts
  • 4.3 from 18 reviews

Cons

  • Only 18 reviews
  • Rough threads and short life in some comments
  • No stated thickness or brake line

Best for: A glove-box spare for light DIY, when you already own a nut you trust.

Less suitable: Daily trade use, thin cutting discs, and brake grinders.

Fentar quick release nut

Rank 9

Fentar quick release nut

∼£12

Our view

The Fentar two-pack is about £11.99, and 4.2 from 151 amazon.co.uk reviews is one of the larger unbranded samples. Reviews mention an M14 fit on common grinders, and also quality that varies from nut to nut, rust in storage, and nuts that seize or snap under heavy use. Comments on this style of nut include a failure to clamp a 1 mm cutting disc. At this price you are close to a SabreCut single without a stated diameter or thickness. There is no pin-spanner note and no brake line. It can be a spare pair for a site grinder if you inspect the threads on arrival and keep a pin spanner ready. It is a lot to pay for a generic pack beside Jesiah’s about £6.29 two-pack.

Pros

  • 151 amazon.co.uk reviews, a larger generic sample
  • Two nuts in the pack
  • Listing claims a tool-free M14 fit on common brands

Cons

  • 4.2 stars, with rust, seize, and snap comments
  • About £11.99 without a stated thickness
  • No pin-spanner or brake line

Best for: A spare pair on a site grinder you already know is M14, if you inspect the threads first.

Less suitable: Buyers who want a published thickness, or who can spend similar money on one SabreCut nut.

Oavie M14 nut set

Rank 10

Oavie M14 nut set

Our view

Oavie’s two-pack is about £6.39 with 4.2 from 22 amazon.co.uk reviews. Buyers who are positive mention the price and hand changes. The sample is small beside Milwaukee’s 2,229 ratings or SabreCut’s 579, and the pattern on cheap packs is soft metal, rust, or a poor grip on thin discs. This listing does not give thickness, a maximum grinder size, or a brake line. Twenty-two reviews can show that some people fitted it. They cannot show that it will still undo after a hot 1 mm cut. Use it as an occasional DIY spare, and keep a pin spanner for the day your fingers are not enough.

Pros

  • About £6.39 for two nuts
  • Listing claims a tool-free M14 change
  • 4.2 from 22 reviews

Cons

  • Small review file next to Milwaukee and SabreCut
  • No stated thickness or brake line
  • Soft metal and thin-disc grip show up on this kind of pack

Best for: Occasional DIY disc swaps when you want a cheap spare and will check the thread.

Less suitable: A daily trade grinder, or a thin cutting disc you have not trial-fitted.

Chromovax quick release nut

Rank 11

Chromovax quick release nut

Our view

Chromovax is a two-pack at about £4.79 and the weakest star line here, 3.6 from 17 amazon.co.uk reviews. Some comments still describe an easy disc change. Others report rust, snapped lugs, or a nut that will not hold a thin wheel. That mix is why the score sits at the bottom of the rated packs, even though the price looks like a bargain next to Milwaukee. Thickness and brake suitability are not stated. A throwaway spare is the only honest use, and only after you inspect the threads and try the disc you actually own. Do not make it the nut you trust for a day’s cutting.

Pros

  • About £4.79 for two nuts
  • Some reviewers still report an easy disc change
  • Listing claims a tool-free fit

Cons

  • 3.6 from 17 reviews, the weakest stars in the set
  • Rust, snapped lugs, and poor grip on thin wheels
  • No stated thickness or brake line

Best for: A spare you can afford to reject after checking threads and disc clamp.

Less suitable: Any job where a snapped or loose nut would stop the work.

Veagafoo quick release nut

Rank 12

Veagafoo quick release nut

Our view

Veagafoo is a four-pack at about £9.29, about £2.32 a nut, and the amazon.co.uk file has no customer-review line. You are paying for quantity with no star count to set beside Milwaukee or SabreCut. Fit, thickness, and durability have to be checked on delivery, the same as any unbranded M14 nut. Four nuts can make sense for a workshop that loses clamp nuts and already knows the spindle is M14×2.0. They do not make sense as the first nut on a braking grinder, because nothing on the page says the nut is approved for a quick stop. Until reviews exist, treat the pack as unproven stock rather than a tested spare.

Pros

  • Four nuts at about £9.29
  • Listing claims a tool-free self-locking clamp
  • Useful only as bulk spares once the spindle is confirmed

Cons

  • No amazon.co.uk review line in the capture
  • No stated thickness, brake line, or pin holes
  • You cannot compare stars with the other nuts

Best for: A workshop that already loses M14 nuts and wants several spares in one order.

Less suitable: A first nut, a brake grinder, or any buyer who wants review evidence.

How we compared

Twelve amazon.co.uk listings were scored from the stored pages and the maker lines already on file. Shelf date 19 October 2026. There is no laboratory test. A quick-release nut is not scored as safer than a factory nut. Stars are the listing line. The highest score is the top pick. Best value is the lowest price per nut among nuts that score at least 70 and have at least 50 reviews. One of each. The weights below sum to 100.

Amazon evidence

50%

If there is no star line, this criterion scores 12 and stops. Otherwise the star rating is scaled, review-count bands add points, and the sum is capped at 50.

2

Listing clarity

25%

Full marks need a stated thickness, a maximum grinder size, a brake line and a pin-spanner fallback. A maker diameter and thickness score next. A tool-free claim with those fields blank scores less.

A missing review line, stars under 4.0, and a count under 25 are scored apart from files of at least 50 reviews and files of at least 200 reviews.

Points use the price per nut and the review count. A pack at or under £4 a nut with at least 50 reviews can score the full 10. A 5.0 from two reviews does not.

Angle grinder quick release nut buying guide

Buy the spindle, the grinder diameter and the brake before you buy a star line. A quick-release nut replaces the outer clamp only. Thickness decides which discs close. A review count is a listing figure, not a laboratory panel.

What is an angle grinder quick release nut?

An angle grinder quick release nut replaces only the outer clamping nut. You change a disc by hand instead of hunting for the two-pin spanner. UK buyers usually already own a 115 mm or 125 mm grinder and swap cutting discs with grinding or flap discs. A sound nut starts cleanly on the spindle, clamps the discs you use, and still undoes after a hot cut. It is not a click-on disc system, it does not replace the inner flange or the guard, and it is not a laboratory-tested safety upgrade.

Best for

  • A 115 mm or 125 mm M14 grinder without a brake, when you change discs often
  • Occasional DIY swaps, if you will check the thread and keep a pin spanner
  • Flap discs, when you want a nut with a stated thickness

Not ideal for

  • A quick-stop or brake grinder, unless that exact nut is stated as suitable
  • An X-LOCK tool, or a 5/8 in-11 spindle
  • A 230 mm grinder bought from a title that only says universal

Mistakes to avoid

  1. 1

    Ordering M14 for a 5/8 in-11 spindle

    Bosch Professional’s UK notes give M14×2.0 for EU metric grinders and 5/8 in-11 for many US-market machines. Amazon lines such as “#0-80” or “M14 x 1.25” are not the spindle specification.

  2. 2

    A tall nut on a 1 mm cutting disc

    SabreCut states the GRNSCA at 13.5 mm. Reviewers say that extra height often will not close on a 1 mm cutting disc or sit inside a diamond cup. A slim nut, stated around 8–9 mm, leaves more of a flap disc usable.

  3. 3

    The small FIXTEC on a quick-stop grinder

    Article 4932352473 is stated up to 150 mm and Milwaukee excludes it from brake and quick-stop machines. The 115–230 mm universal FIXTEC is a different product and is not in this set.

What to weigh up

Spindle, diameter and brake

High

The first check is the thread cut into the spindle, not the thread printed in an Amazon table. Bosch Professional’s UK notes give the EU metric spindle as M14×2.0 and the disc bore as 22 mm. Many US-market grinders use 5/8 in-11. Values such as “#0-80” and “M14 x 1.25” show up in these listings and are ignored as the spindle specification. Diameter and brake come next.

Thickness, free thread and a seized nut

High

Nut height changes which discs clamp. SabreCut states the slim GRNSCB at 45 mm across and 8.9 mm thick, and the taller GRNSCA at 46 mm and 13.5 mm. Slim nuts leave more of a flap disc usable. Tall nuts help when a factory nut is too shallow for a deep flap or a stripper disc, and they are what reviewers say will not close on a 1 mm cutting disc. Most of the generic packs do not state a thickness at all. Free thread sits beside height.

Which option suits you?

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

Occasional DIY disc changes

You lose the pin spanner and change a disc a few times a month on a grinder you already know is M14. The Jesiah two-pack is the best value at about £6.29, with 4.6 from 55 amazon.co.uk reviews. Thickness and a brake line are not stated, so check the thread and keep a pin spanner.

Frequent changes on a small M14 grinder

You swap cut and grind discs on one 115 mm or 125 mm M14 grinder without a brake, and you want pin holes. The Milwaukee FIXTEC 4932352473 is the top pick at about £13.79, with 4.7 from 2,229 reviews. It is stated up to 150 mm and about 8 mm thick. It is not for a quick-stop machine.

Flap discs on a 115 or 125 mm grinder

You mostly grind or use flap discs, and you want a stated thickness. The SabreCut GRNSCB is about £10.99, stated at 45 mm and 8.9 mm, with 4.7 from 579 reviews. Hand-tighten only. It is a weaker choice if every job is a 1 mm cutting disc, and the brake line is not stated.

Common questions about angle grinder quick release nuts

What is an angle grinder quick release nut?
An angle grinder quick release nut replaces only the outer clamping nut, so you can change a disc by hand instead of with a two-pin spanner. It does not replace the inner flange or the guard, and it is not a click-on disc system. A sound nut starts on the right spindle, clamps the discs you use, and still comes undone after a hot cut. It is not scored here as safer than a factory nut, and no laboratory test was done.
Which quick release nut is the top pick?
The top pick is the Milwaukee FIXTEC 4932352473, listed at about £13.79, with 4.7 from 2,229 amazon.co.uk reviews. UK trade listings describe article 4932352473 for M14 spindles on grinders up to 150 mm, at about 8 mm thick, with pin holes for a pin spanner. Milwaukee excludes it from brake and quick-stop machines. It suits a 115 mm or 125 mm M14 grinder without a brake, when you change discs often. It is not the separate universal FIXTEC for 115–230 mm grinders and rapid braking.
Which nut is the best value?
The best value is the Jesiah two-pack at about £6.29, about £3.15 a nut, with 4.6 from 55 amazon.co.uk reviews. In this comparison that badge is the lowest price per nut among nuts scoring at least 70 with at least 50 reviews. Thickness, a maximum grinder size and a brake line are not stated. Reviews mention easy hand swaps, and also rust if the nut is stored damp. Check that the spindle is M14×2.0. It is a weak substitute if you need a stated brake exclusion and pin holes.
Will every nut fit an M14 spindle?
Not every listing will. Bosch Professional’s UK notes give the EU metric spindle as M14×2.0 and the disc bore as 22 mm. Many US-market grinders use 5/8 in-11. Amazon tables in this set also show junk values such as “#0-80” and “M14 x 1.25”. Ignore those as the spindle specification. Confirm the thread cut into your spindle before you order. A photograph of a spanner does not mean the inner flange is included. If the spindle or the inner flange is damaged, stop and get a competent person.
Can I use a quick release nut on a brake grinder?
Only when the maker says that particular nut is suitable. Milwaukee excludes 4932352473 from quick-stop and brake grinders. The M14 universal FIXTEC, stated for 115–230 mm and rapid braking, is a different product and is not one of these twelve listings. Some amazon.co.uk reviews of other nuts describe the nut and the disc loosening when a brake engages. Where a listing is silent, treat brake use as unknown. Do not fit the small FIXTEC to a 230 mm grinder because the title says universal.
How do thickness and disc type affect the clamp?
Thickness decides which discs the nut can close on. SabreCut states the slim GRNSCB at 45 mm and 8.9 mm, and the taller GRNSCA at 46 mm and 13.5 mm. A slim nut leaves more of a flap disc usable. A tall nut helps when the factory nut is too shallow for a deep flap, and that extra height often fails to close on a 1 mm cutting disc. Metabo’s Quick flange nut asks for at least 8 mm of free spindle thread.
What should you do before you change a disc?
Isolate the power before you change a disc. Keep the guard and the side handle, and do not grind with a cutting wheel. At work, PUWER 1998 regulation 9 requires adequate training, and HSE HSG17 is the abrasive-wheel guide. PUWER does not apply to purely domestic use, but a wheel can still burst at home. Bonded wheels should show EN 12413 and a maximum speed at least as high as the grinder. HSE SR21 asks for eye protection. Hand-tighten only.
Do I need a new angle grinder as well?
The nut only replaces the outer clamp on a grinder you already own. Buyers in this category usually have a 115 mm or 125 mm machine and have lost the pin spanner. If you are still choosing the machine, use the angle grinder comparison, then match the nut to that spindle, diameter and brake. A click-on system such as X-LOCK has no clamping nut, so none of these parts fits it. A 5/8 in-11 spindle needs a different thread. This page does not rank grinders.

Our verdict

The top pick is the Milwaukee FIXTEC 4932352473 at about £13.79, with 4.7 from 2,229 amazon.co.uk reviews, a stated limit of 150 mm, about 8 mm thickness, pin holes, and an explicit exclusion for quick-stop grinders. The best value is the Jesiah two-pack at about £6.29, about £3.15 a nut, with 4.6 from 55 reviews, if you will check the M14 thread yourself. The SabreCut GRNSCB is the slim nut with a stated 8.9 mm thickness. The taller GRNSCA is stated at 13.5 mm. None of these scores is a laboratory test, and none of these nuts is a safety upgrade over a factory nut.
