Item Details
- The Makita 224512-1 is a genuine industrial-grade original equipment manufacturer (OEM) replacement lock nut designed for high-torque, high-velocity heavy-duty angle grinders and disc sanders. This mechanical fastener provides the axial clamping force necessary to secure abrasive grinding wheels, cut-off discs, diamond blades, and multi-discs to a tool's high-speed rotating spindle.
Features
- Precision-machined solid steel stock construction for extreme mechanical vibration resistance
- Dual-pin spanner wrench receptacles for leverage-assisted manual torque application
- Precision-engineered concentric fit minimizes rotational wobble and harmonic vibration
- Anti-loosening flange seat resists backing off under inertial deceleration forces
- Hardened threads prevent stripping, deformation, or galling under extreme torque
- Chemical resistance against moisture, cutting fluids, concrete dust, and atmospheric corrosion
- Symmetrically placed pin-holes ensure balanced weight distribution across the axis of rotation
