QJO40A - Williams - 1‑1/4" Open‑End Torque Head – J‑Shank

Williams QJO40A 1‑1/4" Open‑End Torque Head – J‑Shank
The Williams QJO40A 1‑1/4" Open‑End Torque Head is engineered for technicians who demand precise torque application, exceptional accessibility, and rugged durability when working with mid‑large imperial fasteners. Featuring a secure J‑shank connection, this torque head integrates seamlessly with Williams torque wrenches and torque multipliers—ensuring stable, repeatable torque transfer during high‑load industrial applications.

Its ultra‑slim open‑end profile makes it ideal for engaging fasteners in recessed, narrow, or obstruction‑heavy spaces where box‑end torque heads cannot operate. Built from premium alloy steel and precision‑machined to maintain dimensional accuracy, the QJO40A delivers long‑term performance across heavy‑equipment service, utilities, industrial plant maintenance, and oil & gas operations.
