Williams Comfort Products QJO22A Torque Wrench Head

Product Description

The WILLIAMS COMFORT PRODUCTS QJO22A is an open-end torque wrench head sized at 11/16 inch, designed for use with J-shank torque wrench handles in SAE applications. The head accepts a 0.425-inch J-type shank and delivers a maximum torque of 60 foot-pounds, making it suitable for fastener work that requires controlled and repeatable tightening force. The center of fastener to retaining pin measures 2.5 inches. Weighing just 0.16 pounds, this compact head is built for trade professionals who need accurate torque application in tight or hard-to-reach fastener locations.

This torque wrench head is used in mechanical, HVAC, plumbing, and general trade service applications where an open-end head is required to access fasteners that a standard socket cannot reach. It is sold individually and is appropriate for both residential and light commercial service work. Technicians working on equipment panels, piping connections, and mechanical assemblies will find this head useful where fastener geometry limits socket access.

Installation Notes

This head is installed by a qualified technician onto a compatible J-shank torque wrench handle. Ensure the retaining pin is fully seated before applying torque to prevent head separation during use.
