Williams Comfort Products JHW1198B Combination Wrench

Product Description

The WILLIAMS COMFORT PRODUCTS JHW1198B is a combination wrench with a 2 7/8 inch opening, featuring both open and box end configurations on a single tool. The open end uses a SUPERCOMBO profile with specially designed grooves that redirect wrenching force away from fastener corners, reducing the risk of rounding. The box end uses a SUPERTORQUE 12-point design that contacts flat surfaces behind fastener points rather than the corners themselves, allowing higher torque application without deforming hex fasteners. The satin-chrome finish provides corrosion resistance and a clean working surface. This wrench is sized for heavy-duty fasteners and is suited for use by mechanics, millwrights, and industrial maintenance technicians.

The JHW1198B is built for professional use in industrial, aerospace, and general mechanical applications where fastener integrity and torque accuracy matter. 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. It also functions on all common 6-point hex fasteners, offering flexibility across a wide range of service situations. Both the open and box end openings are identical in size, simplifying tool selection when switching between ends during a job.

Key Features

• SUPERCOMBO open end directs wrenching force away from fastener corners to reduce rounding
• SUPERTORQUE 12-point box end contacts flat surfaces behind fastener points for higher torque capacity
• Meets or exceeds aerospace specification AS 954 and ANSI B107.6 for precision torque applications
• Compatible with all common 6-point hex fasteners in addition to 12-point applications
• Box and open end openings are the same size for consistent fitment across both ends
• Satin-chrome finish for corrosion resistance and durability

Compatibility

Designed for use on standard 2 7/8 inch hex and 12-point fasteners in industrial, mechanical, and aerospace service environments. Meets Federal Specification ANSI B107.6 and SAE AS 954.

Installation Notes

This wrench is a hand tool requiring no power source or special installation. Ensure the correct opening size is matched to the fastener before applying torque. Inspect the wrench for cracks or deformation before use, and do not use extension bars or cheater pipes on combination wrenches, as this can exceed safe torque limits and damage the tool or fastener.
