ABSTRACT:
A top jaw adapted for mounting on and attachment to the master jaw of a conventional work holding chuck and simultaneously during attachment thereof to be located radially against a fixed stop by a double T-nut of unique configuration, the latter being movable by an actuator screw in T-slots provided in the jaws, one portion of the T-nut and the complementary T-slot in the top jaw in which it is mounted being inclined with respect to and sloping toward the interface between the top and master jaws so that tightening of the T-nut by the actuator screw forces the top jaw radially against the stop and simultaneously axially against the mating surface of the master jaw, the taper angle of T-nut and the lead angle of the screw threads mutually cooperating to lock the top jaw on the master jaw in use.
