Groz TQE/1-2/ST10 Torque Extension Bar Set, 1/2" Drive, 10 Pc

This Groz kit has ten 1/2" drive torque extension bars, each preset to a different torque value from 65 to 150 ft-lb (90 to 200 Nm), for tightening lug nuts and similar fasteners without over-tightening and distorting a wheel or rotor. Made from Chrome Molybdenum steel with a 1/2" square drive at both ends, each bar is colour-coded and engraved with its torque figure so the right one is easy to pick out on the job. Once that torque is reached, the bar flexes to absorb further force, making it well suited to use with pneumatic or cordless impact wrenches. Each bar measures 7-11/16 inches (195 mm) overall.
