Keys are used to retain parts on a shaft, typically by fitting into a keyway in the shaft and a corresponding slot in the component being attached. Keys alone do not hold the mated components together, but rather prevent them from rotating relative to one another. Keys can come in a variety of shapes, including rectangular and square, not just round.
