Williams Comfort Products JHW1210BSC Combination Wrench

Product Description

The WILLIAMS COMFORT PRODUCTS JHW1210BSC is a 5/16 inch combination wrench built for trade and industrial use. It features a SUPERCOMBO open end and a SUPERTORQUE box end, both with identical openings. The SUPERTORQUE box design applies wrenching force to the flat surfaces of a fastener rather than the corners, reducing the risk of rounding or deforming hex points under high torque. The SUPERCOMBO open end uses specially designed grooves to direct force away from fastener corners. Overall length is 5.75 inches. Weight is 0.08 pounds. The wrench ships in an industrial black finish and meets ANSI B107.6 and SAE AS 954 specifications.

This wrench is suited for maintenance, repair, and installation work across HVAC, plumbing, electrical, and general mechanical trades. The SUPERTORQUE box end meets or exceeds aerospace specification AS 954 for 12-point fasteners as defined by AS 870, making it appropriate for precision torque applications. It also works on all common 6-point hex fasteners and offers a measurable advantage over conventional box end wrenches in both flexibility and economy. Typical use cases include equipment service, panel work, and mechanical assembly in residential and commercial settings.

Installation Notes

This wrench is installed and used by licensed tradespeople and mechanical technicians across a range of service and installation tasks. Always ensure the correct opening size is seated fully on the fastener before applying torque. Inspect the wrench for wear or damage before use. Do not use extension cheater bars on hand wrenches, as this can exceed tool design limits and damage fasteners.
