One New Aftermarket Replacement Woodruff Key - 1/4 x 1-1/8 (ANSI/ASME 809, SAE No. 18)
This 1/4 x 1-1/8 inch semi-circular Woodruff key is a standard replacement fastener used to secure rotating components -- such as pulleys, gears, flywheels, and sprockets -- to a shaft. Seated in a half-moon keyway cut into the shaft, the key prevents independent rotation between the shaft and the hub while also acting as a designed fail-safe that protects more expensive components from damage under excessive load. The part number A-WK26-AI identifies this as an aftermarket replacement conforming to ANSI/ASME B17.2 standard dimensions.
