Torque Head 1 3/8" Open End J Shank - Wrench
Williams QJO44A 1-3/8" Open-End Torque Head J-Shank
The Williams QJO44A 1-3/8" Open-End Torque Head is engineered for technicians who need accurate torque application, superior accessibility, and industrial-grade durability when working with large imperial fasteners. Featuring a robust J-shank connection, this torque head attaches securely to Williams torque wrenches and torque multipliers—ensuring stable, repeatable torque delivery in high-load environments.
With its ultra-slim open-end profile, the QJO44A reaches fasteners located in confined, recessed, or obstruction-heavy areas where box-end or thicker torque heads cannot be used. Manufactured from premium alloy steel and precision-machined to tight tolerances, this torque head resists deformation and wear while delivering consistent performance under heavy torque.
Trusted across industries such as oil & gas, utilities, power-generation, heavy-equipment maintenance, and industrial plant operations, the QJO44A is built for professionals who demand dependability and precision.
