Abstract
A tool for adjusting extremely tight lug nuts, such as often found on tractor-trailer trucks, consists of a socket wrench pulled by a screw and anchored against another lug nut coaxial to the one being adjusted. A hand crank turns the screw, which in turn pulls the handle of the socket wrench toward the anchor yielding very high torque multiplication. The tool is elongated and shaped to permit its use in the tight space found in the annular recess surrounding the hubs of most truck wheels.
