Williams Comfort Products QJO36A Torque Wrench Head

Product Description

The WILLIAMS COMFORT PRODUCTS QJO36A is an open-end torque wrench head designed for precision fastening applications where controlled torque is critical. Built to SAE specification, this head accepts a J-type shank measuring 0.425 inches and delivers a maximum torque of 60 foot-pounds. The 1-1/8 inch open-end design allows access to fasteners in tight spaces where a closed socket cannot seat. The center-of-fastener to retaining-pin distance measures 2-1/2 inches. Mechanics, industrial technicians, and trade professionals working on equipment assemblies that require calibrated torque use this type of interchangeable head with compatible beam or click-style torque wrenches.

This torque wrench head is suited for industrial and trade service environments where repeatable fastener torque is required on 1-1/8 inch SAE hardware. It is appropriate for mechanical and equipment assembly work, including applications in HVAC, plumbing, and general mechanical service where fastener integrity is critical. The open-end head style allows engagement on flats where a socket-style head cannot be used, making it a practical addition to a torque wrench interchangeable head set.

Key Features

• Open-end head style for access on fasteners where sockets cannot seat
• 1-1/8 inch SAE sizing for common heavy-duty hardware
• J-type shank at 0.425 inches for compatibility with J-shank torque wrench handles
• Maximum torque rating of 60 foot-pounds
• Center-of-fastener to retaining-pin distance of 2-1/2 inches for accurate torque correction calculations
• Compact profile at 0.5 inches height for use in confined spaces

Compatibility

Designed for use with J-shank interchangeable torque wrench handles that accept a 0.425-inch J-type shank. Verify shank compatibility with your torque wrench handle before installation.

Installation Notes

This head is installed by a qualified mechanic or trade technician onto a compatible J-shank torque wrench handle. Ensure the retaining pin is fully seated before applying torque to prevent head ejection under load. When using an open-end torque wrench head, apply the appropriate correction factor to the handle setting to account for the extended effective length. Always de-energize or depressurize any system before torquing fasteners on pressurized components.
