Stahlwille Torque Wrenches have blank ends to accept interchangeable insert tools (sizes 9 x 12 or 14 x 18). The unique triggering cam mechanism means that the internal mechanism is only under load when force is applied to the wrench; there is no need to back the wrench off after use. The internal mechanism is extremely resistant to mechanical wear and is protected against dirt ingress. Suitable for use in the clockwise or anti-clockwise direction, simply by turning the wrench and insert tool over. The two-component handle is made of extremely tough, impact resistant plastic, which is resistant to oils, grease, fuels, brake fluids and Skydrol. The torque wrench has a clearly visible twin scale (Nm and ft.lb). It is quick and easy to set using the QuickSelect rapid setting. Max deviation of indication ± 3%. Supplied with factory calibration certificate, valid from day of first use. MADE IN GERMANY. Stahlwille 730N Torque Wrench. Overall length: 607mm.Capacity: 80 to 400Nm / 60 to 300 ft.lb.
