Williams Comfort Products QZX66ADP Torque Wrench Head

Product Description

The WILLIAMS COMFORT PRODUCTS QZX66ADP is a 2-1/16 inch torque wrench head designed for high-torque fastening applications in mechanical, industrial, and trade service environments. This head features a 15-degree offset box end with a 12-point configuration and a Z dual-pin shank, allowing it to mate with compatible drive torque wrenches for precise controlled tightening. It handles a maximum torque of 480 ft-lb, making it suited for heavy-duty fastener work where accurate torque application is critical. Licensed mechanics, millwrights, HVAC technicians, and plumbers working on large flange bolts, pipe fittings, or mechanical equipment rely on heads like this for repeatable, code-compliant torque procedures.

This torque wrench head is intended for use in applications requiring controlled torque on larger fasteners, including mechanical room equipment, piping flanges, and heavy HVAC or industrial assemblies. The offset box-end design provides clearance in tight or recessed bolt locations where a straight head cannot access. The dual-pin shank provides positive engagement with the driving wrench to prevent slippage under high load. It is sold as a single unit and is appropriate for professional shop and field use.

Key Features

• 2-1/16 inch opening for large fastener applications
• 15-degree offset box end for clearance in confined spaces
• 12-point contact geometry for reduced rounding risk on fastener heads
• Z dual-pin shank for secure positive engagement with compatible torque wrenches
• Maximum torque rating of 480 ft-lb for heavy-duty service

Compatibility

Designed for use with compatible Z dual-pin drive torque wrenches accepting interchangeable heads. No specific compatible wrench models were provided in the product data.

Installation Notes

This torque wrench head should be installed by qualified tradespeople familiar with torque fastening procedures. Ensure the drive torque wrench is set to the correct torque value before use and that the dual-pin shank is fully seated before applying load. Do not exceed the 480 ft-lb maximum torque rating. Follow applicable industry codes and equipment manufacturer torque specifications when tightening flanges, bolts, or fittings.
