Torque Head 1 1/4" Open End J Shank - Wrench

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.
