Williams Comfort Products QXX58A Torque Wrench Head

Product Description

The WILLIAMS COMFORT PRODUCTS QXX58A is a 15-degree offset box end torque wrench head designed for high-torque fastening applications in mechanical and industrial service work. Built around a 1 13/16-inch, 12-point box end configuration, it delivers up to 240 ft-lb of torque through a 0.735-inch X-shank drive interface. The offset head geometry allows access to fasteners in recessed or obstructed locations where a straight wrench cannot seat properly. At 0.75 pounds, the head is solid enough for heavy-duty use without adding unnecessary bulk to the assembly. Licensed technicians and journeymen mechanics in HVAC, plumbing, and general mechanical trades will find this head suited for demanding field and shop applications.

This torque wrench head is intended for use with compatible X-shank torque wrench handles in mechanical service environments where precise, high-torque fastener seating is required. The 15-degree offset angle makes it particularly useful in tight engine bays, mechanical rooms, and utility spaces where clearance around large fasteners is limited. It is sold as an individual head and is not supplied with a handle. Typical applications include large-diameter pipe flange bolting, compressor service, and structural fastening tasks that call for controlled torque application in confined spaces.

Key Features

• 1 13/16-inch, 12-point box end for positive engagement on large fasteners
• 15-degree offset head angle improves clearance access in tight or obstructed spaces
• Maximum rated torque of 240 ft-lb for heavy-duty fastening work
• 0.735-inch X-shank drive interface for compatibility with matching torque wrench handles
• Compact form factor at 0.75 pounds for reduced hand fatigue during extended use

Compatibility

Designed as a replacement or supplemental torque wrench head for use with X-shank torque wrench handles accepting a 0.735-inch shank. Verify handle and shank compatibility before installation.

Installation Notes

Installation of this torque wrench head requires a compatible X-shank torque wrench handle rated for the intended torque range. Confirm the shank is fully seated and secure before applying load. Always relieve system pressure and de-energize or isolate equipment before torquing fasteners on live mechanical systems. Follow applicable codes and equipment manufacturer torque specifications for the fastener being serviced.
