Williams Comfort Products JHW1218BSC Combination Wrench

Product Description

The WILLIAMS COMFORT PRODUCTS JHW1218BSC is a 9/16 inch combination wrench designed for professional fastener work in industrial and mechanical service environments. It features a SUPERCOMBO open end with specially designed grooves that redirect wrenching force away from fastener corners, reducing the risk of rounding. The SUPERTORQUE box end applies force to the flat surfaces behind the hex points rather than the corners themselves, allowing higher torque application without deforming the fastener. Overall length is 8 3/4 inches. The part weighs 0.304 pounds and carries an industrial black finish.

This wrench is suited for industrial maintenance, mechanical assembly, and trade service applications where precision torque and fastener integrity matter. The box end meets aerospace specification AS 954 for 12-point fasteners as defined by AS 870, making it appropriate for precision torque-to-tension applications. The open end and box end openings are identical at 9/16 inch, so both ends engage the same fastener size. It is sold individually and is appropriate for use by mechanics, millwrights, HVAC technicians, and other trades working with hex fasteners in tight-tolerance environments.

Installation Notes

This wrench is a hand tool requiring no power source or lockout procedure before use. Follow applicable torque specifications for the fastener and joint being serviced as defined by the equipment manufacturer or applicable codes. Inspect the wrench for wear or damage before each use and do not use extension bars or cheater pipes on this tool, as doing so may exceed the design load and create a safety hazard.
