QJO52A - Williams - 1‑5/8" Open‑End Torque Head – J‑Shank

Williams QJO52A 1‑5/8" Open‑End Torque Head – J‑Shank
The Williams QJO52A 1‑5/8" Open‑End Torque Head is engineered for professionals who require exceptional access, strength, and precision when tightening large imperial fasteners. Built with a secure J‑shank connection, this torque head integrates seamlessly with Williams torque wrenches and multipliers—providing stable, accurate torque delivery in demanding industrial environments.

With its ultra‑slim open‑end profile, the QJO52A reaches fasteners located in recessed, tight, or obstructed areas where box‑end or thicker torque heads cannot operate. Constructed from premium alloy steel and precision‑machined for repeatable accuracy, this head withstands heavy torque loads while resisting wear, deformation, and rounding.

Ideal for heavy‑equipment service, industrial plant maintenance, utilities, structural bolting, and oil & gas field operations, this torque head delivers the durability and performance required by professional technicians.
