Williams QJO16A 1/2" Open-End Wrench Head J-Shank
The Williams QJO16A 1/2" Open-End Wrench Head is built for technicians who need precise torque application, excellent accessibility, and industrial-grade durability when working with smaller imperial fasteners. Designed with a secure J-shank interface, this wrench head connects solidly to Williams torque wrenches and torque multipliers—delivering stable, accurate, and repeatable torque control.
Its slim open-end design allows you to reach fasteners located in tight, recessed, or obstruction-heavy areas where box-end heads cannot fit. Precision-machined from high-strength alloy steel, the QJO16A resists deformation, rounding, and wear under continuous torque loads—making it a reliable choice for demanding environments such as utilities, manufacturing, industrial plants, and oil & gas field maintenance.
