Williams Comfort Products QYO46A Torque Wrench Head

Product Description

The WILLIAMS COMFORT PRODUCTS QYO46A is an open-end torque wrench head engineered for precise fastener torquing in demanding trade applications. Sized at 1 7/16 inch with a 0.560-inch Y-type shank, this head attaches to compatible torque wrench handles to deliver controlled torque up to 160 ft-lb. The open-end design provides access to fasteners in confined spaces where a standard box or socket head cannot seat. Licensed tradespeople working in HVAC, plumbing, and mechanical service rely on this type of tooling when accurate torque values are required by manufacturer specifications or code compliance.

This torque wrench head suits residential and commercial service work where precise torque application is critical. Typical applications include tightening flare fittings, unions, and mechanical fasteners on HVAC equipment, refrigeration systems, and piping assemblies. The SAE sizing makes it compatible with standard inch-measurement fasteners common in North American mechanical systems. Its compact head geometry, with a center-of-fastener to retaining pin distance of 3 inches, allows positioning in tight equipment enclosures.

Key Features
