Williams Comfort Products QYO40A Torque Wrench Head

Product Description

The WILLIAMS COMFORT PRODUCTS QYO40A is an open-end torque wrench head designed for precision fastening applications in trade and industrial settings. Built to accept a 0.560-inch Y-type shank, this head delivers a maximum torque of 160 foot-pounds and fits a 1-1/4-inch SAE fastener. The center-of-fastener to retaining pin measurement is 3 inches, providing the clearance needed for confined or obstructed fastener locations. Mechanics, pipefitters, and HVAC technicians who require accurate torque application on larger fasteners will find this head a practical addition to an interchangeable torque wrench system.

This torque wrench head is suited for residential and commercial installation and service work where access to standard socket-drive tools is restricted. It is commonly used when torquing large fittings, flanges, or structural fasteners that require an open-end approach. The SAE sizing makes it appropriate for domestic equipment and piping systems. It is sold individually and is intended for use with a compatible interchangeable-head torque wrench handle, not as a standalone tool.

Key Features

• 1-1/4-inch open-end head for SAE fasteners
• Maximum torque rating of 160 foot-pounds
• 0.560-inch Y-type shank for interchangeable wrench handle compatibility
• 3-inch center-of-fastener to retaining pin distance for clearance in tight spaces
• Compact form factor at 4.3 inches tall and 2.6 inches in length
• Lightweight at 0.64 pounds for reduced fatigue during repeated use

Compatibility

Designed for use with interchangeable-head torque wrench systems accepting a 0.560-inch Y-type shank. Verify shank and drive compatibility with your existing torque wrench handle before installation.

Installation Notes

Installation of this torque wrench head requires a compatible interchangeable torque wrench handle with a matching Y-type shank receiver. Always confirm the retaining pin is fully seated before applying torque. Follow applicable torque specifications from the equipment manufacturer or relevant codes such as ASME B16.5 for flanged connections. Do not exceed the 160 foot-pound maximum torque rating to avoid tool damage or fastener failure.
