Williams Comfort Products QYO36A Torque Wrench Head

Product Description

The WILLIAMS COMFORT PRODUCTS QYO36A is an open-end torque wrench head engineered for precise fastener torque application in professional trade environments. Sized at 1-1/8 inches with a Y-type shank measuring 0.560 inches, this head attaches to a compatible torque wrench drive and delivers a maximum torque output of 160 foot-pounds. The open-end head design provides access to fasteners in confined spaces where a standard box or socket wrench cannot seat. This tool is intended for use by licensed tradespeople — HVAC technicians, plumbers, and pipefitters — who require controlled torque on large fasteners during installation or service work.

This torque wrench head suits applications involving large hex fasteners in HVAC, refrigeration, plumbing, and mechanical systems. The open-end configuration allows the head to engage fasteners from the side, making it well-suited for tight equipment rooms, rooftop units, and piping assemblies where straight-on access is restricted. The 1-1/8 inch size addresses common large-format nuts and fittings encountered in commercial and residential mechanical work. Sold as an individual head unit and compatible with the appropriate Y-shank torque wrench handles.

Installation Notes

This head is installed and removed by qualified tradespeople familiar with torque wrench tools and fastener specifications. Ensure the shank is fully seated and the retaining pin is engaged before applying torque. Do not exceed the rated 160 foot-pound maximum torque to avoid fastener or tool damage. Consult the fastener manufacturer's torque specification before use.
