Williams Comfort Products JHW1198C Combination Wrench

Product Description

The WILLIAMS COMFORT PRODUCTS JHW1198C is a 2 15/16 inch combination wrench with both an open end and a 12-point box end, designed for professional use in mechanical, aerospace, and industrial service applications. The open end uses a SUPERCOMBO profile with machined grooves that redirect wrenching force away from fastener corners, reducing the risk of rounding. The box end uses a SUPERTORQUE design that contacts the flat surfaces of hex fasteners behind the points rather than at the corners, enabling higher torque application without deforming the fastener. Both openings share an identical 2 15/16 inch size. The wrench is finished in satin chrome.

This wrench is suited for mechanical and industrial technicians working with hex fasteners in high-torque applications. The SUPERTORQUE box end meets aerospace specification AS 954 for 12-point fasteners as defined by AS 870, making it appropriate for precision torque applications where accurate torque-to-tension relationships are required. The SUPERCOMBO open end provides advantages over conventional open-end designs on standard 6-point hex fasteners, giving the technician improved grip and reduced fastener damage risk in tight or repetitive-use scenarios.

Key Features

• SUPERCOMBO open end with grooves that direct force away from fastener corners
• SUPERTORQUE box end contacts flat fastener surfaces, not corners, for higher torque without deformation
• Meets aerospace specification AS 954 for 12-point fasteners per AS 870
• Compatible with all common 6-point hex fasteners with advantage over conventional box end wrenches
• Box and open end openings are identical in size
• Satin-chrome finish; meets ANSI B107.6 and SAE AS 954

Compatibility

Designed for use on 2 15/16 inch hex and 12-point fasteners in mechanical, industrial, and aerospace service environments where both standard and high-torque applications are required.

Installation Notes

This wrench is a hand tool intended for use by mechanics and industrial technicians. Always ensure the wrench opening is fully seated on the fastener before applying torque. Inspect the wrench for cracks or wear before each use, and do not use an extension bar or cheater pipe on combination wrenches, as this can exceed the tool's design load and cause failure.
