FLANGED HEX NUT

Secure wheel mounting is essential for safe angle-grinder operation. A stripped, cracked, or bent retaining nut can allow the accessory to wobble or loosen at high speed. Check that the wheel type, bore, inner flange, and spindle threads are correct before ordering a replacement. Match the nut to the full tool model and parts diagram. Disconnect power, wear eye protection and gloves, and use the approved wrench. Never install a damaged wheel or force a nut with the wrong thread onto the spindle.
