The WILLIAMS COMFORT PRODUCTS QXO56A is an open-end torque wrench head designed for precise fastener tightening in demanding trade applications. With a 1.75-inch open-end jaw and a maximum torque rating of 240 ft-lb, this head handles heavy-duty fastening tasks where standard socket access is not practical. The X-type shank measures 0.735 inches and connects to compatible torque wrench handles for controlled, repeatable torque application. It is used by HVAC technicians, plumbers, pipefitters, and mechanical contractors who require accurate torque on large fasteners in confined or awkward installation spaces.
This torque wrench head is suited for SAE fastening applications in residential and commercial mechanical work. The open-end design allows engagement with fasteners where a socket cannot fit over the bolt head or nut, making it a practical tool in equipment installation, pipe flange work, and structural mechanical assemblies. The center of the fastener to the retaining pin measures 4.5 inches, giving technicians clear reference for positioning during use.
Designed as an OEM-style replacement torque wrench head for use with compatible X-shank torque wrench handles requiring a 1.75-inch open-end SAE head.
This torque wrench head is used by licensed mechanical trades including HVAC technicians, pipefitters, and plumbers. Before use, ensure the wrench handle and head shank type and size are fully compatible and the retaining pin is properly seated. Always de-energize or isolate the system being serviced before performing fastener work on pressurized or live equipment. Refer to equipment manufacturer torque specifications and applicable codes such as IFGC or IPC for required fastener torque values.
