Williams Comfort Products QYO34A Torque Wrench Head

Product Description

The WILLIAMS COMFORT PRODUCTS QYO34A is a 1-1/16 inch open-end torque wrench head designed for use with compatible torque wrench handles in demanding fastening applications. Built to a Y-type shank with a 0.560 inch shank diameter, this head transfers torque input cleanly to the fastener. Maximum rated torque is 160 ft-lb, making it suitable for medium-to-heavy duty bolted connections. The center-of-fastener to retaining pin measurement is 3 inches. Mechanics, HVAC technicians, and plumbers working in confined spaces or on flanged fittings rely on interchangeable torque wrench heads like this one to reach fasteners that standard socket or box-end tools cannot access.

This torque wrench head is used in trade settings where precise torque application is required on hex fasteners in tight or offset positions. The open-end head style allows it to engage fasteners from the side without requiring axial access, which is common when working on pipe flanges, equipment mounting hardware, and structural connections. It is sold individually and is intended for professional-grade torque wrench systems that accept Y-type shank heads.

Installation Notes

Installation of this torque wrench head is performed by qualified mechanics or trade professionals familiar with torque tool systems.

Inspect the head for wear or damage before each use and replace if any deformation is found.
