Rear Axle Keys

If the taper is what only holds the grip then why is there a key in there anyway? No reason for hub to axle location orientation.

It is to keep it from creeping. Say you let the clutch out real fast. the key would keep it from creeping. But under normal driving with the nut proper torque it would not move.
