Williams Comfort Products QZX72A Torque Wrench Head

Product Description

The WILLIAMS COMFORT PRODUCTS QZX72A is a heavy-duty torque wrench head designed for high-torque fastening applications in mechanical, industrial, and trade service environments. The head features a 15-degree offset box end configuration with a 12-point design, accepting fasteners sized at 2.25 inches. It connects via a Z-type shank measuring 0.990 inches, allowing it to mate with compatible torque wrench handles for controlled, accurate torque delivery. Maximum rated torque is 480 foot-pounds, making this head suitable for demanding bolted joint work on large mechanical assemblies. Weighing 3.17 pounds, the QZX72A is built for durability in professional shop and field environments. Licensed trades and industrial mechanics rely on this type of tooling for repeatable, code-consistent fastening procedures.

This torque wrench head is intended for use in applications requiring precise, high-torque fastener installation on large SAE fasteners. Typical use cases include heavy equipment service, industrial pipefitting, structural mechanical work, and commercial HVAC or refrigeration system assembly where large-diameter bolted connections must meet specified torque values. The SAE sizing standard makes it compatible with inch-series fastener sets common in North American mechanical trade environments. It is sold as an individual unit and is intended for use with a separate torque wrench handle that accepts the Z-type shank.
