Protect your wheels, wheel studs, and brake rotors with STEELMAN torque extensions. The STEELMAN 50061-5XA 5-Piece 1/2-Inch Drive Torque Extension Set is designed to prevent damage to wheels, studs, and brake rotors by reducing the risk of overtightening lug nuts which can result in sheared stud bolts, rounded lug nuts, and warped rotors. When used with an electric or pneumatic impact wrench these 8-inch extension bars will limit the effective output of the wrench to a preset amount of torque and anything above that will cause the extension to flex and absorb the extra impact. Each torque stick is machined to a specific maximum torque and then color coded for easy identification: yellow at 65ft-lb, blue at 80ft-lb, gray at 100ft-lb, white at 120ft-lb, and aqua at 140ft-lb of torque. These torque sticks are made of resilient chrome molybdenum (Chromoly) steel that are then given their color-coded powder coating for increased corrosion resistance and to make it easy to distinguish them among other tools. Kit includes a convenient blow-molded black storage case.
