Abstract: The hand tool embodying this invention allows push nuts to be quickly and easily removed from axle rods and other shafts. The tool has a specialized head welded to a long handle. The tool head includes an end socket head and an extractor. The socket head has an open throat within which the caps of push nuts are seated. The sides of the socket head are cut down to form two axial cusps on either side of the socket head. The extractor is welded to the socket head and terminates in a flat claw, which extends downward in front and angles slightly toward the open mouth of the socket head.

Abstract: The press tool includes a frame, an abutment part mounted to one end of the frame, and a lever actuated ram mounted to the other end of the frame. The ram includes a pair of interchangeable fittings (one for affixing the push nuts and one for removing the push nuts). Rocker plates pivotally connect the rams to a long lever, which extends and retracts the ram through a tubular sleeve mounted to the frame. The assembly fitting includes a magnet that holds a push nut to the ram. When the lever is depressed, the ram extends and the push nut is pressed axially onto the axle rod. The removal fitting has a two pronged head. When the lever is depressed, the prongs deform the push nut flange, which bends back the teeth that secure the push nut to the axle.
