5PC 1/2-IN DRIVE TORQUE EXTENSION SET

The STEELMAN 50061-5XA 5pc 1/2-Inch Drive Torque Extension Set is designed to prevent damage by reducing the risk of overtightening lug nuts. When used with an electric or pneumatic impact wrench these 8" 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 & color coded: yellow at 65ft-lb, blue at 80ft-lb, gray at 100ft-lb, white at 120ft-lb, and aqua at 140ft-lb of torque.
