1/2" Sq. Dr. Torsion Bar 17mm x 140Nm Length 200mm

Ko-ken torsion bars represent precision engineering designed for controlled torque application in professional fastening operations. This 1/2 inch square drive torsion bar delivers reliable 140Nm torque limiting capability through advanced spring steel construction, protecting critical fasteners and components from over-tightening damage. The precision-machined 17mm hex profile provides secure engagement with compatible fasteners while the integrated torsion mechanism flexes predictably at the specified torque threshold, giving technicians clear tactile feedback when proper tension is achieved. This intelligent design prevents costly thread stripping, component damage, and warranty issues in automotive assembly, machinery maintenance, and precision mechanical applications where exact torque specifications are critical.
