Browse M14 quick release flange nuts from Bosch, Makita, DeWalt & Sealey. Fast UK delivery on professional accessories. About Locking Nuts Locking nuts are essential fastening components designed specifically for securing discs, pads and accessories onto power tools, particularly angle grinders. MyToolShed.co.uk stocks a comprehensive range of locking nuts compatible with leading professional brands including Bosch Professional, Makita, DeWalt, Sealey and Faithfull. These precision-engineered components feature standard M14 and M10 thread sizes to fit various grinder models and disc diameters from 115mm through to 230mm. Modern locking nut designs have evolved to include quick-release mechanisms and toolless systems, such as Bosch SDS Clic, Makita Ezy Nut and DeWalt Quick Release variants, which significantly reduce accessory change times on site. Traditional flange nuts remain available for older pre-1990 grinder models, ensuring MyToolShed provides solutions for both legacy equipment and current professional power tools. Applications Locking nuts are indispensable across numerous trades and applications: Metal fabricators and welders – securing cutting and grinding discs for steel preparation and finishing work Construction workers and groundworkers – fixing cutting discs for concrete, stone and masonry materials Automotive mechanics and body shop technicians – attaching polishing pads and grinding discs for bodywork repairs General builders and maintenance engineers – fastening various abrasive accessories for cutting and surface preparation DIY enthusiasts – securing accessories safely for home improvement projects Stone masons and tilers – fitting diamond cutting discs for tile and stone work Choosing The Right Locking Nuts Selecting the correct locking nut requires careful consideration of several key factors: Thread size compatibility: Most modern angle grinders use M14 threads, whilst some backing pads and smaller tools require M10 threads. Always verify your tool's specifications before purchasing. Brand compatibility: Whilst many locking nuts are universal, certain manufacturers like Bosch, Makita and DeWalt produce model-specific nuts designed for their quick-change systems. Check your grinder model number against product descriptions at MyToolShed.co.uk to ensure proper fitment. Disc diameter requirements: Locking nuts are engineered for specific disc size ranges. Verify your nut is rated for your intended disc diameter, whether 115mm, 125mm, 180mm or 230mm. Quick-release features: Toolless systems eliminate the need for spanners, dramatically speeding up accessory changes. Consider upgrading to quick-change nuts if your grinder supports them for improved productivity on site. Age of equipment: Pre-1990 grinder models often require different nut designs. Ensure you select nuts specifically designated for older equipment if applicable. Frequently Asked Questions Are locking nuts universal across different grinder brands? Many standard M14 locking nuts are interchangeable between brands, but quick-release systems like Bosch SDS Clic or Makita Ezy Nut are typically proprietary. Always check thread size and compatibility with your specific grinder model before purchasing. How often should I replace my angle grinder locking nut? Replace locking nuts immediately if you notice thread damage, cross-threading, or if the nut fails to secure discs tightly. Regular visual inspection before each use helps prevent disc slippage and potential accidents. Can I use a quick-release nut on any angle grinder? Not all grinders support quick-release systems. Check your tool's manual or spindle design to confirm compatibility. Standard threaded nuts remain the safest option for grinders not designed for toolless systems. ## Products - [Makita Genuine 224554-5 M14 Angle Grinder Locking Nut](https://www.mytoolshed.co.uk//makita-genuine-224554-5-m14-angle-grinder-locking-nut/prod/233020/) - £5.49 - [Faithfull M14 Quick Change Angle Grinder Locking Nut](https://www.mytoolshed.co.uk//faithfull-m14-quick-change-angle-grinder-locking-nut/prod/697365/) - £10.95 - [Bosch PRO SDS Clic Quick Change Flange M14 Locking Nut for Angle Grinders](https://www.mytoolshed.co.uk//bosch-pro-sds-clic-quick-change-flange-m14-locking-nut-for-angle-grinders/prod/56536/) - £19.95 - [Bosch Backing flange Nut for 115 - 230mm Angle Grinders](https://www.mytoolshed.co.uk//bosch-backing-flange-nut-for-115-230mm-angle-grinders/prod/56580/) - £8.49 - [Bosch Quick Locking Nut for GWS 18V 10 C and SC](https://www.mytoolshed.co.uk//bosch-quick-locking-nut-for-gws-18v-10-c-and-sc/prod/492248/) - £18.95 - [Bosch Round Locking Nut for Flat Disc GCS Cutter](https://www.mytoolshed.co.uk//bosch-round-locking-nut-for-flat-disc-gcs-cutter/prod/56540/) - £21.95 - [Sealey M14 Pad Nut for 170mm Backing Pad](https://www.mytoolshed.co.uk//sealey-m14-pad-nut-for-170mm-backing-pad/prod/27552/) - £6.99 - [Sirius Quick Change Flange Locking Nut for Angle Grinders](https://www.mytoolshed.co.uk//sirius-quick-change-flange-locking-nut-for-angle-grinders/prod/406268/) - £9.95 - [Bosch M14 Angle Grinder Locking Nut](https://www.mytoolshed.co.uk//bosch-m14-angle-grinder-locking-nut/prod/56537/) - £6.95 - [Makita 195354-9 Toolless Ezy Nut For Grinders](https://www.mytoolshed.co.uk//makita-195354-9-toolless-ezy-nut-for-grinders/prod/235705/) - £63.95 - [Sealey M14 Quick Change Angle Grinder Locking Nut](https://www.mytoolshed.co.uk//sealey-m14-quick-change-angle-grinder-locking-nut/prod/518124/) - £14.95 - [Sealey M10 x 1.25mm Nut for PTC/BP3 Backing Pad 90mm](https://www.mytoolshed.co.uk//sealey-m10-x-125mm-nut-for-ptc-bp3-backing-pad-90mm/prod/27537/) - £8.49 - [Sealey M10 x 1.5mm Nut for PTC/BP3 Backing Pad 90mm](https://www.mytoolshed.co.uk//sealey-m10-x-15mm-nut-for-ptc-bp3-backing-pad-90mm/prod/196131/) - £8.49 - [DeWalt DE8503 Quick Release Angle Grinder Flange Nut](https://www.mytoolshed.co.uk//dewalt-de8503-quick-release-angle-grinder-flange-nut/prod/348432/) - £59.95 - [Sealey M14 x 2mm Nut for PTC/BP4 Backing Pad 104mm](https://www.mytoolshed.co.uk//sealey-m14-x-2mm-nut-for-ptc-bp4-backing-pad-104mm/prod/27539/) - £10.95 - [Bosch 2603340018 Pre 1990 Angle Grinder Locking Nut](https://www.mytoolshed.co.uk//bosch-2603340018-pre-1990-angle-grinder-locking-nut/prod/57363/) - £4.95 - [Bosch 2608000625 M14 Pre 1990 Angle Grinder Locking Nut](https://www.mytoolshed.co.uk//bosch-2608000625-m14-pre-1990-angle-grinder-locking-nut/prod/289674/) - £9.95 - [Bosch 1603345004 M14 Flange Nut for 180mm - 230mm Angle Grinders](https://www.mytoolshed.co.uk//bosch-1603345004-m14-flange-nut-for-180mm-230mm-angle-grinders/prod/236022/) - £7.49 --- **URL**: https://www.mytoolshed.co.uk//locking-nuts/cat/2000773/
