Description:
The sliding clamp holds the wrench to the wheel hub. There are provisions for matching the socket size to the axle nut. The spring in the handle forces the socket against the nut.

This is one of those axle nut wrenches that works by clamping to the wheel hub so the axle and nut are turned on and off together.
