Williams Comfort Products QZO58ADP Torque Wrench Head

Product Description

The WILLIAMS COMFORT PRODUCTS QZO58ADP is an open-end torque wrench head designed for high-torque fastening applications in industrial and mechanical service environments. Built to a 1 13/16 inch open-end specification with a Z dual-pin shank, this head delivers a maximum torque rating of 480 ft-lb, making it suitable for heavy-duty assembly and disassembly tasks. The dual-pin shank provides positive engagement and secure positioning during operation. Licensed technicians and industrial mechanics working on large mechanical assemblies rely on this style of torque head when precise, repeatable torque application is required on large fasteners.

This torque wrench head is intended for use in industrial maintenance, mechanical assembly, and service applications where high-torque open-end access is needed. The open-end design allows engagement on fasteners in tight or obstructed spaces where a closed socket cannot be used. It is sold as an individual unit and fits drive configurations compatible with Z dual-pin shanks. The 5 3/4 inch center-of-fastener-to-retaining-pin dimension should be confirmed against the drive tool before installation.
