Best angle grinder quick release nut for an M14 grinder

Updated: October 2026

You want one nut for the grinder you already own, not twelve near-identical photos. On amazon.co.uk the review files in this set run from two ratings to 2,229, and the prices captured on 19 October 2026 run from about £3.99 to about £13.79. The best angle grinder quick release nut here depends on a stated size, a slim or tall profile, or a spare you can reject. None of these nuts was lab-tested, and none is a claim that a disc cannot come loose. The full scores sit on the [angle grinder quick release nut comparison](/hub/tools/angle-grinder-quick-release-nut). A qualifying purchase can earn a commission at no extra cost to you.

Who the Milwaukee FIXTEC is for

The top pick is Milwaukee’s small FIXTEC, article 4932352473, for a 115 mm or 125 mm M14 grinder without a brake, when you change discs often. UK trade listings describe it for spindles up to 150 mm, at about 8 mm thick, and Milwaukee excludes it from brake and quick-stop machines. The folding lever is the grip. The pin holes are what you use when heat beats your fingers. It is not the universal FIXTEC for 115–230 mm grinders with rapid braking. That is a different article. About £13.79 is a lot for one nut if you only swap a disc a few times a month. The sequence with the power isolated is on how to fit a quick release nut.

Slim versus tall SabreCut

SabreCut gives you two stated heights at the same about £10.99, and the choice is the disc. GRNSCB, the slim SUPERLOK, is 45 mm across and 8.9 mm thick. The lower profile leaves more of a flap disc usable. Hand-tighten only. Complaints cluster when it is still too thick for a 1 mm cutting disc. This file states no pin holes and no brake rating. GRNSCA, the taller SUPERLOK-MAX, is 46 mm and 13.5 mm. Buyers choose it when a factory nut is too shallow for a deep flap or a stripper. Reviewers say that height will not close on a 1 mm cutter and can foul a tight 115 mm guard. Some reviews on braking grinders describe the nut loosening as the brake bites, so height is not a safety feature. Leave both if every job is a paper-thin cutter you have not trial-fitted.

When a two-pack is enough

A two-pack is enough when the grinder is already a known M14 and you will try your own disc before you trust the nut. Jesiah is the best value: about £6.29 for two, about £3.15 each, the largest generic sample after Fentar. Reviews mention easy hand swaps, and rust if the nut is stored damp. Thickness, grinder size, pin holes and a brake line are missing. Fentar is 4.2 from 151, but about £11.99 for two is close to one SabreCut without a stated thickness. Times Mark at about £5.75 is 4.8 from only 15 reviews. Oavie and Rohmerique, both under £7 with about twenty reviews, are spare pairs rather than a settled record. Jesiah is a poor stand-in if you needed a brake exclusion and pin holes.

When to skip a generic pack

Skip a generic pack when it is the only nut for a day’s cutting, when the grinder has a brake, or when the file is tiny. Chromovax is the weakest line, 3.6 from 17 at about £4.79, with rust, snapped lugs and a nut that will not hold a thin wheel. Uskerb at about £3.99, 4.3 from 18, can be a glove-box spare beside a nut you already trust. Eighteen ratings are not a durability record. Masonvex’s 5.0 is two reviews at about £7.99. Veagafoo’s four-pack at about £9.29 has no review line. Four nuts can restock a workshop that already loses M14 clamps. They are unproven as a first nut. If the machine is Bosch X-LOCK, none of these nuts fits.

Common questions

What is the best angle grinder quick release nut if I change discs every day?
For a 115 mm or 125 mm M14 grinder without a brake, the small Milwaukee FIXTEC leads this set: about £13.79, 4.7 from 2,229 reviews, about 8 mm thick, up to 150 mm, with pin holes. Milwaukee excludes this article from quick-stop machines. If you mostly use flaps and want a stated slim size, SabreCut GRNSCB at 8.9 mm and about £10.99 is the alternative, though its brake line is not stated.
Is a 5.0-star nut better than Milwaukee?
No. Masonvex’s 5.0 is two reviews. Milwaukee’s 4.7 is 2,229. A perfect line on a tiny sample does not outrank a large file, and Masonvex states no thickness or brake rating. Weigh the review count beside any published size.
Which SabreCut should I buy?
Buy GRNSCB, 45 mm and 8.9 mm, for grinding and flap discs on a 115 mm or 125 mm M14 grinder. Buy GRNSCA, 46 mm and 13.5 mm, when a factory nut is too shallow for a deep flap or stripper. Both are about £10.99. The tall nut often misses a 1 mm cutter. Neither file states a brake rating.
Is the Jesiah two-pack good enough for DIY?
It is the best value here for occasional swaps: about £6.29 for two nuts and 4.6 from 55 reviews. Confirm M14×2.0 and trial your disc, because thickness and brake suitability are absent. Reviews mention rust if it is stored damp. It is the wrong primary nut if you need pin holes.
Why not just buy the cheapest nut?
Uskerb at about £3.99 can be a glove-box spare beside a nut you trust. Eighteen reviews and no stated thickness are not a case for daily cutting. Chromovax at about £4.79 is 3.6 from 17, including snapped lugs and a poor grip on thin wheels.
Do these nuts fit every UK grinder?
They are outer clamps for an M14 spindle, usually on 115 mm or 125 mm machines. They do not fit 5/8"-11 spindles or Bosch X-LOCK mounts. The small FIXTEC is also the wrong nut for a brake or a 230 mm grinder. Match the spindle before you compare stars.
