Hobart 00-435297 Hardened Key

The Hobart 00-435297 Hardened Key is a machined metal piece used to hold rotating components to a shaft to give a mechanical connection that does not slip with the load. It is fitted in matching keyways on the shaft and driven part, holding the two together in such a way that torque transmission is possible. The hardened key is installed into the assembly in the setup of the equipment or in its maintenance to provide the alignment and rotational stability of the mating components.
