Williams Comfort Products QZO72ADP Torque Wrench Head

Product Description

The WILLIAMS COMFORT PRODUCTS QZO72ADP is a 2.25-inch open-end torque wrench head designed for high-load fastening applications. Built with a Z Dual Pin shank, this head delivers controlled torque up to 480 foot-pounds, making it suitable for heavy-duty industrial and mechanical assembly work. The open-end head design allows access to fasteners in confined or angled positions where a standard wrench cannot seat properly. Measuring 4.5 inches in length and weighing 4.48 pounds, it is a solid, purpose-built tool for trades requiring precise torque application on large fasteners.

This torque wrench head is intended for use with compatible dual-pin torque wrench drives in industrial maintenance, heavy equipment service, and mechanical contracting environments. The SAE sizing makes it appropriate for standard inch-based fastener systems commonly found in HVAC equipment rigging, mechanical room installations, and structural assembly. It is sold as a single unit and is best suited for journeymen mechanics, millwrights, and service technicians working on high-torque fastener applications.
