QYO56A - Williams - 1‑3/4" Open‑End Torque Head – “Y” Shank

Williams QYO56A 1‑3/4" Open‑End Torque Head – “Y” Shank
The Williams QYO56A 1‑3/4" Open‑End Torque Head is built for technicians who require precise torque control, exceptional durability, and reliable access when working with large imperial fasteners. Designed with a “Y”‑style shank, this torque head offers a secure, stable interface with Williams torque wrenches and modular torque systems—ensuring consistent performance in high‑torque industrial environments.

Featuring a slim open‑end profile, the QYO56A is ideal for use in tight, recessed, or obstructed locations where traditional box‑end torque heads cannot operate. Constructed from premium alloy steel and precision‑machined for accuracy, it delivers repeatable torque application and long‑term durability in demanding industries including heavy‑equipment maintenance, utilities, industrial plants, and oil & gas field service.
