The Bosch PRO SDS Clic Quick Change Flange M14 Locking Nut is a quick-release locking nut designed for fast, tool-free fastening and loosening of angle grinder accessories, including grinding discs, diamond cutting discs, and grinding heads. Compatible with all angle grinders featuring an M14 thread manufactured from August 1990 onwards, this locking nut is a practical upgrade for contractors and tradespeople who frequently change discs on site. The 22.23 mm bore suits both standard locking nut angle grinders and concrete grinders. When fitting, ensure the disc is centred at the supporting flange rather than at the nut. The available thread length protruding over the thickest tool must exceed 6 mm for correct and safe installation.
