It fits into keyways (slots) on a shaft and a mating hub, pulley, or gear to transmit torque and prevent rotation. The KS4512 has a small width of 1/4 inch and a larger width of 5/16 inch, making it useful for connecting components that have different keyway sizes. It is commonly replaced when the key becomes worn, sheared, or when swapping out pulleys or hubs that require a step key.
