Threaded cooperating elements of cam means formed on the other end of the pin and in the hole in one rotated position engage and clamp the insert in the pocket and axial recesses in the threads of each are adapted to receive the threads of the other so as to allow free axial travel of the pin when it is in another rotated position.
