The Siegen 1/2" Drive Torque Wrench is a professional-grade precision tool designed for accurate torque application in automotive, engineering and mechanical work. This micrometer-type torque wrench features a heat-treated steel ratchet head that has been fully hardened and tempered for exceptional durability, with chrome plating providing excellent corrosion resistance in workshop environments. The wrench incorporates a micrometer torque range adjustment system allowing precise setting across its 40-210Nm (30-155lb.ft) range, making it ideal for tasks requiring controlled tightening such as cylinder head bolts, wheel nuts and suspension components. The flip reverse ratchet mechanism enables efficient operation in both clockwise and anti-clockwise directions, whilst the 467mm length provides good leverage without being unwieldy.
