Williams Comfort Products QXX42A Torque Wrench Head

Product Description

The WILLIAMS COMFORT PRODUCTS QXX42A is a 1 5/16 inch, 15-degree offset box end torque wrench head designed for precision fastening in demanding trade environments. Built with a 12-point configuration, it delivers broad contact across fastener flats to reduce rounding during high-torque applications. The 0.735-inch X-type shank connects to compatible torque wrench handles for controlled, repeatable results. Rated to a maximum torque of 240 ft-lb, this head is suited for heavy-duty mechanical work where accurate torque application is critical. Technicians across HVAC, plumbing, and general mechanical trades rely on this type of interchangeable wrench head for efficient fastening in tight or offset access points.

This torque wrench head is appropriate for use in both residential and commercial service scenarios where standard open-access tooling cannot reach fasteners at a straight angle. The 15-degree offset geometry allows the technician to clear obstructions while maintaining controlled torque delivery. It is sold individually and is well suited for field service kits, shop use, and installation work requiring precise bolt torque across a range of mechanical assemblies.
