Protect your wheels, wheel studs, and brake rotors with this STEELMAN torque stick. The STEELMAN 60173 80 ft-lb 1/2-Inch Drive x 17mm Torque Stick is designed to prevent damage to wheels, studs, and brake rotors by reducing the risk of over-tightening lug nuts which can result in sheared stud bolts, rounded lug nuts, and warped rotors. This stick measures 8-5/8-inches long and has a 17mm socket on the end. When used with a 1/2-inch drive electric or pneumatic impact wrench it will limit the effective output of the wrench to 80 ft-lb (108 Newton-meters) 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 red powder coat to make it easy to pick out among other tools or in a crowded toolbox.
