Williams Comfort Products QZO68A Torque Wrench Head

Product Description

The WILLIAMS COMFORT PRODUCTS QZO68A is an open-end torque wrench head designed for high-torque fastening applications in demanding trade environments. Built to SAE standards, it accepts a Z-type shank with a 0.990-inch shank diameter and delivers a maximum torque output of 480 ft lb. The open-end head measures 2.125 inches and spans 5.75 inches from the center of the fastener to the retaining pin. This wrench head is used by licensed mechanics, pipefitters, and industrial technicians who require precise, repeatable torque on large fasteners in tight or restricted access situations.

The QZO68A is suited for heavy-duty industrial and mechanical service work where large fastener sizes and high torque values are common. It is typically used in HVAC equipment installation, large-scale plumbing assemblies, and industrial piping work where standard torque wrenches cannot reach or engage properly. The open-end design allows engagement on fasteners that a box-end or socket configuration cannot access. Each unit is sold individually.

Installation Notes

Installation and use of this torque wrench head should be performed by qualified technicians familiar with proper torque procedures. Before use, verify that the shank connection is fully seated and the retaining pin is secured. Always derate torque values when using an extended-reach wrench head, following standard torque correction calculations. Do not exceed the 480 ft lb maximum torque rating.
