Williams Comfort Products QYO42A Torque Wrench Head

Product Description

The WILLIAMS COMFORT PRODUCTS QYO42A is an open-end torque wrench head designed for precision fastening applications where controlled torque is critical. Built to SAE standards, it fits a 1 5/16 inch fastener and accepts a Y-type shank with a 0.560 inch shank size. The head delivers a maximum torque of 160 ft-lb, making it suitable for demanding mechanical assembly and service work. The center of fastener to retaining pin measures 3 inches. This tool is used by mechanics and trade technicians who require accurate, repeatable torque application in tight or specific-access fastening scenarios.

The QYO42A open-end torque wrench head is appropriate for use in HVAC, plumbing, and general mechanical service applications where SAE fasteners require torque control. It is sold as an individual unit and is intended for use with a compatible torque wrench handle that accepts the Y-type shank drive.
