Williams QJO14A 7/16" Open-End Wrench Head J-Shank
The Williams QJO14A 7/16" Open-End Wrench Head is engineered for technicians who require reliable torque performance, excellent accessibility, and long-lasting durability when working with small imperial fasteners. Built with a secure J-shank interface, this wrench head attaches firmly to Williams torque wrenches and torque multipliers—providing stable, repeatable torque accuracy in demanding industrial environments.
Its slim open-end geometry gives technicians direct access to fasteners located in tight, narrow, or obstructed areas where box-end torque heads cannot operate. Constructed from high-strength alloy steel and precision-machined for dimensional accuracy, the QJO14A resists wear, rounding, and deformation under continuous torque cycles—making it a reliable choice for plant maintenance, industrial repair, utilities, and field service.
