  • Patent number: 4103571
    Abstract: The present invention is a tool used to demount polygonal hub nuts from a threaded axle located within a wheel hub. The tool comprises at least two steel bars slidably and rotatably joined by a buckle pivot. Each end of each bar is equipped with a rounded raised surface. The four rounded raised surfaces are dimensioned so the nut engaging end of the tool will fit snugly between one face of the hub nut and the wheel hub. The cross-member on the tool is rotated so lugs on the wheel hub strike a lug protection plate mounted on the cross-member. The tool transfers torque imparted to it by the lug to the hub nut. When not in use, the tool may be collapsed for ease of storage.
