QZO52A - Williams - 1‑5/8" Open‑End Torque Adapter

Williams QZO52A 1‑5/8" Open‑End Torque Adapter
The Williams QZO52A 1‑5/8" Open‑End Torque Adapter is built for industrial technicians who require precision, durability, and exceptional access when working with large imperial fasteners. Its slim open‑end design allows technicians to reach bolts in tight, recessed, or obstructed spaces—making it ideal for applications where box‑end torque heads cannot be used. Perfect for heavy‑equipment maintenance, industrial plant servicing, utilities, construction, and oil & gas environments.

Crafted from premium alloy steel and precision‑machined to exact tolerances, the QZO52A ensures smooth, repeatable, and accurate torque application even under heavy‑load conditions. Fully compatible with Williams torque wrenches, torque multipliers, and modular torque systems, this adapter provides reliable performance in mission‑critical fastening tasks.
