Williams Comfort Products QZO32A Torque Wrench Head

Product Description

The WILLIAMS COMFORT PRODUCTS QZO32A is a 1-inch open-end torque wrench head designed for precision fastening in demanding trade applications. Built with a Z-type shank measuring 0.990 inches, this head attaches to compatible torque wrench handles and delivers controlled torque output up to 298 foot-pounds. The open-end design allows access to fasteners in tight or obstructed locations where a closed wrench cannot seat. Licensed mechanics, industrial maintenance technicians, and commercial HVAC and plumbing installers rely on this type of tooling when specification-critical bolted connections require verified torque values.

This torque wrench head suits applications where large-diameter fasteners must be tightened to engineered torque specs. Typical uses include mechanical room equipment installation, large pipe flange connections, commercial rooftop unit mounting hardware, and structural fastener work. The SAE sizing makes it appropriate for inch-standard fasteners found throughout North American mechanical and HVAC systems.

Installation Notes

This torque wrench head is installed by qualified mechanics and trade technicians familiar with torque-controlled fastening procedures. Ensure the shank is fully seated and the retaining pin is engaged before applying load. Do not exceed the rated maximum torque of 298 foot-pounds. Follow applicable mechanical codes and equipment manufacturer torque specifications when tightening fasteners.
