QXO42A - Williams - 1‑5/16" Open‑End Torque Head

Williams QXO42A 1‑5/16" Open‑End Torque Head
The Williams QXO42A 1‑5/16" Open‑End Torque Head is engineered for industrial professionals who need precise torque delivery, superior access, and heavy‑duty durability when working with medium‑large imperial fasteners. Its slim open‑end configuration allows fastener engagement in tight, recessed, or obstructed areas—ideal for situations where box‑end torque heads cannot operate. This makes the QXO42A a reliable choice across heavy‑equipment maintenance, industrial plant servicing, utilities, construction, and oil & gas applications.

Built from premium alloy steel and precision‑machined to maintain exact dimensional accuracy, the QXO42A ensures smooth, consistent, and repeatable torque transfer even under demanding load conditions. Fully compatible with Williams torque wrenches, torque multipliers, and modular torque systems, this head delivers long‑lasting, professional‑grade performance.
