Williams Comfort Products QZX36A Torque Wrench Head

Product Description

The WILLIAMS COMFORT PRODUCTS QZX36A is a 1-1/8 inch torque wrench head designed for high-torque fastening applications in mechanical and industrial service work. Featuring a 15-degree offset box end with a 12-point configuration, this head delivers up to 480 ft-lb of maximum torque. The Z-type shank measures 0.990 inches and mates with compatible torque wrench handles for controlled, repeatable tightening. It is built for professional trades requiring precise torque application on large fasteners, including HVAC equipment mounting, heavy mechanical assemblies, and industrial piping connections. Sold individually, this is a purpose-built replacement or additional head for professionals who maintain a torque wrench set.

The QZX36A is suited for residential and commercial mechanical service environments where large-fastener torque specs must be met consistently. The offset box end geometry provides clearance in tight or recessed bolt locations, making it practical for equipment installations where a straight access path is not available. Licensed HVAC technicians, pipefitters, and millwrights working on compressor bolting, flange connections, or equipment base fastening will find this head useful in their torque wrench kit.

Installation Notes

Installation of this torque wrench head should be performed by a qualified tradesperson familiar with torque tool operation and applicable mechanical codes.
