Williams Comfort Products JHW1240RSC Combination Wrench

Product Description

The WILLIAMS COMFORT PRODUCTS JHW1240RSC is a combination wrench with a 1 1/4 inch opening, built for professional fastener work where torque accuracy and fastener protection matter. The open end uses a SUPERCOMBO design with grooves that redirect wrench force away from fastener corners, reducing the risk of rounding. The box end features a SUPERTORQUE design that applies wrenching force to the flat surfaces of the fastener rather than the corners, allowing higher torque without deforming hex points. This wrench is finished in Hi-Vis Red for quick identification in a tool layout.

The JHW1240RSC is suited for precision mechanical and industrial applications where torque-to-tension accuracy is required. It meets or exceeds aerospace specification AS 954 for 12-point fasteners as defined by AS 870, making it appropriate for high-specification work. The wrench is also compatible with common 6-point hex fasteners, offering flexibility across a wide range of fastening tasks. Both the box end and open end share identical opening sizes, simplifying wrench selection during a job.

Key Features

• SUPERCOMBO open end directs force away from fastener corners to reduce rounding
• SUPERTORQUE box end contacts flat fastener surfaces, not corners, enabling higher torque application
• Meets or exceeds aerospace specification AS 954 for 12-point fasteners per AS 870
• Compatible with standard 6-point hex fasteners for broad application flexibility
• Box and open end openings are identical for consistent sizing across both ends
• Hi-Vis Red finish for fast tool identification on the job site

Compatibility

Designed for use with 1 1/4 inch 6-point hex and 12-point fasteners across general mechanical and aerospace-grade applications. Conforms to ANSI B107.6 federal specification for combination wrenches.

Installation Notes

This wrench is used by mechanics, millwrights, and industrial technicians across a range of fastening applications. Always select the correct opening size before applying torque to avoid fastener damage. Inspect the wrench for cracks or wear before each use, particularly in high-torque applications. Do not use extension bars or additional leverage devices on hand wrenches unless the tool is specifically rated for that use.
