The Groz 1/2” Torque Extension Bars are used by professionals to tighten lug nuts and other fasteners to pre-set torque values, preventing over-tightening of wheel lug nuts, distortion of wheels and rotors etc. Manufactured from durable Chrome Molybdenum steel, they feature a 1/2” drive on both ends. Once the maximum torque is reached, the extension bar flexes to absorb any further force and prevents over-tightening.  Each bar is color-coded and engraved with torque values, allowing for quick and easy identification on the job. Ideal for use with pneumatic or cordless impact wrenches, the Groz Torque Extension Bars are a reliable tool in any workshop.
