Description
Overview:
This Genuine Makita Woodruff Key (OEM No: 254002-0) is a small, semi-circular steel insert used to lock rotating parts to a shaft. It sits in the shaft keyway and prevents slippage between the shaft and the mating component, helping maintain timing and torque transfer under load. Made from durable metal with a precise profile, it ensures reliable alignment of gears, pulleys or rotor components in Makita power tools. Designed for Makita angle grinders and other selected machines, it is a direct fit for models including 9505BH and 9503BH. A sound key helps protect armatures, gears and bearings from damage caused by movement on the shaft, supporting smooth operation and longer component life.
