Williams Comfort Products QXO54A Torque Wrench Head

Product Description

The WILLIAMS COMFORT PRODUCTS QXO54A is an open-end torque wrench head designed for precision fastening in demanding trade applications. Built to accept an X-type shank measuring 0.735 inches, this head delivers a maximum torque output of 240 foot-pounds, making it suitable for high-load fastening tasks. The 1 11/16-inch open-end head provides direct access to fasteners in confined or awkward spaces where standard torque wrenches cannot reach. It is used by mechanics, HVAC technicians, and industrial service professionals who require controlled torque application with specific head geometry. The center of fastener to retaining pin measures 4.5 inches, providing the clearance needed for accurate torque transfer.

This torque wrench head fits into maintenance and installation workflows where precise torque is required on larger fasteners. It is appropriate for use in mechanical rooms, equipment pads, rooftop unit installations, and industrial service environments. The SAE sizing makes it compatible with inch-standard fastener systems commonly found across HVAC equipment, piping systems, and structural mechanical connections. Technicians working on equipment requiring torque specs in the 200-plus foot-pound range will find this head suitable for those applications.

Installation Notes

Installation and use should be performed by qualified mechanics or licensed trade professionals familiar with torque wrench head attachment and proper torque procedures. Verify that the drive tool shank is fully seated and the retaining pin is engaged before applying torque. Do not exceed the 240 foot-pound maximum torque rating, as overloading can damage the head or the fastener. Always consult the applicable equipment service manual for required torque values before use.
