Protect your wheels, wheel studs, and brake rotors with STEELMAN torque extensions. The STEELMAN 50090A 1/2-Inch Drive Gray 100 ft-lb Torque Extension 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. This 8-inch extension bar will, when used with an electric or pneumatic impact wrench, limit the effective output of the wrench to 100 ft-lb of torque and anything above that will cause the extension to flex and absorb the extra impact. This torque stick is made of resilient chrome molybdenum (Chromoly) steel that has a gray powder coat to make it easy to pick out among other tools or in a crowded toolbox.
