Williams Comfort Products QJO28A Torque Wrench Head

Product Description

The WILLIAMS COMFORT PRODUCTS QJO28A is an open-end torque wrench head engineered for precise fastener torque application in professional trade settings. Sized at 7/8 inch, it accepts a J-type shank measuring 0.425 inches and delivers a maximum torque of 60 foot-pounds. The center of fastener to retaining pin distance is 2.5 inches, giving technicians accurate positional reference during use. At 0.27 pounds, the head is lightweight without sacrificing the structural integrity needed for repetitive, high-load applications. Licensed HVAC technicians, plumbers, and mechanical contractors rely on this type of precision tooling where controlled torque is critical to joint integrity and code compliance.

This torque wrench head is suited for SAE fastener applications across a range of mechanical and trade installations. It is commonly used in scenarios where a standard wrench cannot achieve the controlled torque output required by specifications or manufacturer procedures. The open-end head design allows access to fasteners in tight or partially obstructed spaces, making it practical for equipment service and mechanical assembly work in both residential and light commercial settings.
