Williams QZO44A 1-3/8" Open-End Torque Head
The Williams QZO44A 1-3/8" Open-End Torque Head is engineered for technicians who require precise torque application, excellent accessibility, and long-term durability when working with mid-to-large imperial fasteners. Its slim open-end design allows for fastener engagement in tight, recessed, or obstructed spaces where traditional box-end torque heads cannot operate—making it ideal for industrial maintenance, heavy-equipment servicing, utilities, and oil & gas applications.
Manufactured from premium alloy steel and precision-machined for dimensional accuracy, the QZO44A ensures smooth, reliable, and repeatable torque transfer under heavy-load conditions. Fully compatible with Williams torque wrenches, torque multipliers, and modular torque systems, this open-end head delivers the performance required for mission-critical industrial tasks.
