Product Description
The 500635/A Woodruff Key, featured in image_841fa2.png, is an essential Original Equipment (OE) component designed to prevent relative rotation between a shaft and its attached parts. Its semi-circular shape allows it to sit deeply in a matching curved slot on the shaft, providing a high-strength mechanical lock that can withstand significant torque and engine vibration.
As shown in the official packaging in image_841f83.png, this is a genuine Royal Enfield spare part. Using an authentic key ensures perfect dimensional accuracy, which is critical for maintaining correct engine timing and preventing catastrophic slippage that could lead to engine failure.
