Williams Comfort Products JHW1240SC Combination Wrench

Product Description

The WILLIAMS COMFORT PRODUCTS JHW1240SC is a 1-1/4 inch combination wrench built for trade professionals who demand reliable torque transfer on hex and 12-point fasteners. The box end uses a SUPERTORQUE design that applies wrenching force to the flat surfaces of the fastener rather than the corners, reducing the risk of rounding or deforming the fastener under high torque. The open end uses a SUPERCOMBO profile with machined grooves that similarly redirect force away from corners. Overall length is 17 inches, and the wrench weighs 2.469 pounds. Both ends share the same 1-1/4 inch opening dimension.

This wrench is suited for use in industrial, commercial, and field service environments where fastener integrity matters. It meets aerospace specification AS 954 for 12-point fasteners as defined by AS 870, making it appropriate for precision torque applications. It also conforms to ANSI B107.6 and Federal Specification SAE AS 954. Mechanics, pipefitters, millwrights, and HVAC technicians working on heavy equipment or large-diameter threaded connections will find the dual-end design useful across a range of common hex fasteners.

Key Features

• SUPERTORQUE box end applies force to fastener flats, not corners, reducing deformation risk under high torque
• SUPERCOMBO open end uses directional grooves to shift wrenching force away from fastener corners
• Meets aerospace specification AS 954 for 12-point fasteners per AS 870
• Conforms to ANSI B107.6 Federal Specification for combination wrenches
• Box and open end openings are identical at 1-1/4 inch
• High-polish chrome finish for corrosion resistance and durability

Compatibility

Compatible with all common 6-point hex fasteners and 12-point fasteners with a 1-1/4 inch across-flats dimension. Offers functional advantage over conventional box end wrenches on standard hex fasteners.

Installation Notes

This wrench is a hand tool requiring no power source or fastener modification. Ensure the fastener head is clean and fully seated in the wrench opening before applying torque to avoid slippage. Inspect the wrench for cracks or deformation before each use and do not use extension bars or cheater pipes that exceed the tool's rated design. Follow applicable torque specifications for the fastener grade and application as required by the governing standard or job specification.
