Product Description

The WILLIAMS COMFORT PRODUCTS QXO50A is an open-end torque wrench head designed for precision fastening in demanding trade applications. It accepts a 0.735-inch X-type shank and delivers a maximum torque output of 240 ft-lb, making it suited for high-load bolted connections. The head measures 1 9/16 inches and features a center-of-fastener-to-retaining-pin distance of 4.5 inches, providing the clearance needed for tight or recessed fastener locations. Weighing just 0.33 pounds, it is a compact and durable addition to any professional torque wrench system. HVAC, plumbing, and mechanical tradespeople who work with large-format fasteners or flanged connections will find this head a reliable fit for their interchangeable torque wrench setups.

This torque wrench head is appropriate for commercial and industrial mechanical work where SAE fastener sizes and precise torque application are required. It is commonly used by HVAC technicians, pipefitters, and plumbers when assembling or servicing flanged fittings, large valves, equipment mounting hardware, and structural connections. The open-end design allows access to fasteners in confined spaces where a full socket cannot engage. It is sold individually and is compatible with interchangeable torque wrench systems that accept the X-type shank.
