Secure grinding discs and backing pads on your angle grinder with metal flange lock nuts. This 2 set of 5/8 thread flange nuts features a 41mm outer diameter with outer lock nut and inner flange design for reliable disc retention under high-speed rotation.
Made of metal with precise 5/8-11 threading for smooth installation and removal. The 41mm flange spreads clamping force evenly across the grinding disc surface to prevent warping and vibration during operation. Built to withstand repeated tightening and loosening cycles.
Each set includes one outer lock nut and one inner flange for complete disc mounting on standard 5/8-11 spindle angle grinders. The two sets provide a spare pair for workshop stock or allow simultaneous outfitting of two grinder units.
Standard 5/8-11 thread fits most major brand angle grinders with 5/8 inch arbors. The 41mm flange diameter accommodates common 4.5 inch, 5 inch, and 6 inch grinding discs, cutting wheels, flap discs, and wire brushes for versatile workshop use.
Ideal for metal fabrication, welding shops, construction sites, automotive repair, and home DIY workshops. Use when replacing worn or damaged flange nuts on angle grinders, or keep spare sets in your toolbox for quick disc changes without downtime.
