QZO66A - Williams - 2‑1/16" Open‑End Torque Adapter

Williams QZO66A 2‑1/16" Open‑End Torque Adapter
The Williams QZO66A 2‑1/16" Open‑End Torque Adapter is engineered for industrial technicians who demand precision, strength, and exceptional accessibility when working with large imperial fasteners. Its slim open‑end configuration allows fastener engagement in confined, recessed, or obstructed spaces—places where conventional box‑end torque heads cannot operate. This makes it the ideal tool for heavy‑equipment maintenance, industrial plant servicing, utilities, power‑generation systems, and oil & gas field work.

Manufactured from premium alloy steel and precision‑machined to tight tolerances, the QZO66A delivers smooth, consistent, and repeatable torque transfer under high‑load conditions. It integrates seamlessly with Williams torque wrenches, torque multipliers, and modular torque systems to ensure reliable performance in demanding industrial environments.
