Williams Comfort Products QXO52A Torque Wrench Head

Product Description

The WILLIAMS COMFORT PRODUCTS QXO52A is an open-end torque wrench head designed for precision fastening applications in the trade. Built to an SAE standard, it accepts a 1 5/8-inch fastener and fits an X-type shank measuring 0.735 inches. The head delivers a maximum torque output of 240 foot-pounds, making it suitable for high-load bolted connections encountered by HVAC, plumbing, and mechanical contractors. At 1.4 pounds, the head is compact enough for confined installations while maintaining the structural integrity needed for heavy-duty torque application. Licensed technicians and journeymen mechanics are the primary installers of this type of tooling accessory.

This torque wrench head is used wherever controlled torque is required on large SAE fasteners in mechanical, HVAC, plumbing, and industrial service environments. Its open-end design allows engagement with fasteners in tight or restricted spaces where a closed socket cannot be seated. The 4 1/2-inch center-of-fastener-to-retaining-pin dimension supports reach into recessed or partially obstructed bolt locations. It is well suited for equipment assembly, pipe flange bolting, and mechanical equipment service across both residential and commercial jobsites.

Installation Notes

Installation and use should be performed by qualified mechanics or licensed trade professionals familiar with torque specification requirements. Ensure the torque wrench drive is fully de-energized and the equipment is isolated from any live systems before applying torque to fasteners. Confirm shank seating and retaining pin engagement before applying load to prevent slippage. Follow applicable mechanical codes and equipment manufacturer torque specifications for the fastened joint.
