This is a torque wrench for the RAM "D" sized socket arms (eg. RAM-D-201U). It matches the shape of the knob found on the side of socket arms and gives you an extra tight grip. This wrench was originally made for the military when using the RAM mounts in cold weather, and the knob could not be tightened by hand.
