Williams Comfort Products QZX58A Torque Wrench Head

Product Description

The WILLIAMS COMFORT PRODUCTS QZX58A is a torque wrench head designed for high-torque fastening applications in mechanical and industrial service work. Built with a 15-degree offset box end and a 12-point configuration, this head provides access to fasteners in tight or angled spaces where a straight approach is not practical. The 1 13/16 inch opening accommodates large-format fasteners common in heavy mechanical assemblies. Maximum rated torque is 480 ft-lb, and the Z-type shank measures 0.990 inches for secure engagement with compatible torque wrench drives. Mechanical contractors, millwrights, and heavy-equipment technicians will find this head suited to demanding service environments.

This torque wrench head is appropriate for use in commercial and industrial maintenance settings where large fasteners require precise torque application. The offset box end geometry allows the technician to work at an angle to the fastener axis, which is valuable when clearance is limited by adjacent components, piping, or structural members. It is sold individually and intended for use with a compatible torque wrench handle that accepts a Z-type shank with a 0.990-inch shank diameter.
