Choosing the right option
Match the key to the keyway on your shaft and hub, using the size in the options table. Rectangle key steel suits a keyway where the width and height differ. Imperial and metric keyways are not interchangeable, so check the unit on your shaft. Key steel is supplied in 12" (305mm) lengths and is cut to the length you need.
