Abstract: A jam-proof, tamper resistant lug nut is disclosed for holding a tire rim on a bolt extending from an axle mount. The lug nut comprises a tapered main body with a plurality of rounded, raised wrench engaging surfaces. The main body of the nut includes a proximal end, which abuts against the wheel mounting surface, and a distal end. A threaded hole extends from the proximal end toward the distal end along a longitudinal axis defined by the hole. The main body is further tapered and includes a star-shaped exterior section which decreases in size along the axis toward the distal end.
