Williams Comfort Products QXO34A Torque Wrench Head

Product Description

The WILLIAMS COMFORT PRODUCTS QXO34A is an open-end torque wrench head engineered for precision fastening in demanding trade applications. Designed for use with compatible torque wrench drives, this head accepts a 0.735-inch X-type shank and delivers a maximum torque output of 240 ft-lb. The 1-1/16-inch open-end jaw provides solid contact on hex fasteners, making it well-suited for mechanical, HVAC, and plumbing technicians who need controlled torque on larger fittings and fasteners. The center-of-fastener to retaining-pin distance measures 4.5 inches, contributing to accurate torque transfer. Sold individually.

This torque wrench head is appropriate for residential and commercial service work where fastener integrity is critical. Common applications include tightening flange bolts, large hex-head fittings, and mechanical assembly points that require a verified torque value rather than hand-feel estimation. It is suited for use by HVAC technicians, pipefitters, plumbers, and general mechanical contractors working on equipment requiring SAE fastener sizes in the 1-1/16-inch range.

Installation Notes

Installation should be performed by a qualified trade technician familiar with torque specifications for the fasteners being serviced. Ensure the shank is fully seated and the retaining pin is engaged before applying torque. Do not exceed the 240 ft-lb maximum torque rating. Consult the applicable equipment service manual for required fastener torque values.
