About Key Stock

Make keys for aligning and securing components to power transmission shafts and transmitting torque to the components. Key stock refers to metal bars formed to standard key profiles that can be cut to length. To help prevent key failure, choose a key stock material with the same strength and hardness as the shaft or hub.

Oversized key stock is slightly larger than standard for a snug fit in keyways.
