QZO56A - Williams - 1‑3/4" Open‑End Torque Adapter

Williams QZO56A 1‑3/4" Open‑End Torque Adapter
The Williams QZO56A 1‑3/4" Open‑End Torque Adapter is built for industrial technicians who require accurate torque delivery, exceptional access, and rugged durability when working with large imperial fasteners. Its slim open‑end design provides reliable engagement in tight, recessed, or obstructed areas—making it the ideal choice where box‑end torque heads cannot operate, especially in heavy‑equipment maintenance, industrial machinery service, utilities, construction, and oil & gas environments.

Manufactured from premium alloy steel and precision‑machined to exacting tolerances, the QZO56A delivers smooth, consistent, and repeatable torque transfer even under extreme load conditions. It integrates seamlessly with Williams torque wrenches, torque multipliers, and modular torque systems, ensuring professional‑grade performance for mission‑critical applications.
