Williams Comfort Products QZX42A Torque Wrench Head

Product Description

The WILLIAMS COMFORT PRODUCTS QZX42A is a torque wrench head designed for precision fastening applications where controlled torque output is critical. This head features a 15-degree offset box end configuration with a 12-point design, allowing access to fasteners in tight or angled positions. It accepts a Z-type shank measuring 0.990 inches and is rated for a maximum torque of 480 foot-pounds. Built for trade professionals who require reliable, repeatable torque application, this wrench head is suited for mechanical, industrial, and heavy-duty service work where fastener integrity is non-negotiable.

This torque wrench head is appropriate for use in residential and commercial mechanical service environments, as well as industrial maintenance settings. The offset box end design makes it especially useful in confined spaces where a straight-head tool cannot engage the fastener at the correct angle. Technicians working on HVAC equipment, pipework, structural assemblies, and heavy machinery will find the 480 foot-pound maximum torque rating capable of handling demanding fastening tasks.

Key Features

• 15-degree offset box end provides access to fasteners in restricted or angled work areas
• 12-point design offers more engagement positions and reduces fastener rounding risk
• Maximum torque rating of 480 foot-pounds suits heavy-duty service applications
• Z-type shank with 0.990-inch shank size for compatibility with matching torque wrench drives
• Compact head profile supports use in tight installation spaces

Compatibility

Designed for use with Z-type shank torque wrench drives accepting a 0.990-inch shank; verify shank type and drive size before installation to confirm fitment with your existing torque wrench handle.

Installation Notes

Installation and use should be performed by qualified trade professionals familiar with torque wrench operation and fastener specifications. Ensure the wrench head is fully seated on the drive shank before applying torque. Do not exceed the rated maximum torque of 480 foot-pounds to avoid tool damage or fastener failure. Inspect the head for wear or damage before each use and remove from service if any defects are found.
