Description
Overview:
The Wheel Nut M14 is a genuine Hitachi/Hikoki spare that secures grinding and cutting accessories on compatible disc grinders such as the G12SE2 and G13SE2. Made from robust steel, it threads onto the grinder spindle to clamp the wheel firmly against the backing flange, supporting safe and accurate operation during heavy use. Built to the original specification (OEM No. 339579), it provides a direct fit on Hikoki machines that use an M14 spindle thread. This wheel nut is ideal for replacing a worn, damaged or missing nut, restoring correct retention of discs and helping to prevent wheel slippage. Simple to fit with standard hand tools, it is designed for long service life and consistent performance in workshop, site, and DIY environments.
