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.
