QYO42A - Williams - 1‑5/16" Open‑End Torque Head – “Y” Shank

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.
