About Machine Keys
Cut to standard key profiles and specific lengths, machine keys are used for aligning and securing components to power transmission shafts and transmitting torque to the components. To help prevent key failure, choose key stock material with the same strength and hardness as the shaft or hub.
These keys are tapered along their length to fit tightly into keyways.
