Torque Head 1 5/16" Open End Y Shank - Wrench

Williams QYO42A 1-5/16" Open-End Torque Head "Y" Shank
The Williams QYO42A 1-5/16" Open-End Torque Head is built for technicians who require precise torque control, rugged durability, and reliable access when working with large imperial fasteners. Designed with a "Y"-style shank, this torque head provides a stable, secure interface with Williams torque wrenches and modular torque systems—ensuring consistent, repeatable torque delivery in demanding industrial applications.

Its slim open-end design allows technicians to reach fasteners located in recessed, restricted, or obstructed areas where standard box-end torque heads cannot fit. Manufactured from high-strength alloy steel and precision-machined to maintain optimal engagement, the QYO42A offers consistent torque performance in tough environments such as heavy-equipment repair, utilities, construction, industrial plants, and oil & gas field service.
