Using a genuine OEM replacement clamp nut helps maintain proper wheel alignment and dependable grinder performance.
Common Signs Replacement Is Needed
Replace the disc nut if you notice:

A damaged clamp nut can prevent proper wheel retention and may create unsafe operating conditions.
Installation & Service Notes
Disconnect the grinder from its power source or remove the battery before servicing.
Press the spindle lock to prevent spindle rotation, remove the existing clamp nut using the appropriate spanner wrench, and inspect both the spindle threads and backing flange for wear or debris. Install the grinding wheel or accessory according to the manufacturer's instructions, thread the 68254-02 Disc Nut onto the spindle by hand to avoid cross-threading, and tighten securely using the proper wrench. Rotate the accessory by hand before operation to verify proper seating and clearance.
Important: Always verify your grinder model and original part number before ordering. Never overtighten the clamp nut, and always use the correct backing flange and accessory for the intended application. Use genuine OEM DeWalt / Black & Decker replacement parts to maintain factory fit, secure wheel retention, and safe grinder operation.
Maintenance Recommendations
- Inspect the clamp nut and spindle threads before each accessory change.
- Clean debris from the spindle and flange surfaces regularly.
- Replace worn or damaged clamp nuts immediately.
- Use only compatible grinding wheels and accessories.
- Tighten accessories using the proper spanner wrench.
- Use genuine OEM replacement parts to maintain factory fit, secure accessory retention, and long-term angle grinder performance.
