Williams Comfort Products QXO44A Torque Wrench Head

Product Description

The WILLIAMS COMFORT PRODUCTS QXO44A is an open-end torque wrench head designed for precision fastening applications in trade and industrial settings. Built to accept a 0.735-inch X-type shank, it delivers a maximum torque output of 240 ft-lb, making it suitable for heavy-duty fastener work. The 1 3/8-inch open-end jaw fits standard SAE fasteners, and the center-of-fastener to retaining-pin measurement of 4.5 inches provides the clearance reference needed for accurate torque application. Mechanics, millwrights, and service technicians working with large-diameter SAE hardware will find this head a direct fit for demanding torque tool setups.

This torque wrench head is intended for use in maintenance, repair, and installation environments where controlled torque on SAE fasteners is required. It is well suited to HVAC equipment installation, mechanical system assembly, and industrial service work where large fastener sizes are common. The X-type shank interface connects to compatible torque wrench drives, allowing the head to be used as part of a modular torque tool system. It is sold as a single unit.

Installation Notes

Installation and use should be performed by qualified mechanics or service technicians familiar with torque tool systems. Confirm that the shank type and size of the receiving drive match the QXO44A specifications before applying torque. Do not exceed the 240 ft-lb maximum torque rating. Ensure the fastener and wrench head are fully seated before applying load to prevent slippage or fastener damage.
