Williams Comfort Products JHW1216SC Combination Wrench

Product Description

The WILLIAMS COMFORT PRODUCTS JHW1216SC is a combination wrench with a 1/2 inch opening, an overall length of 8 inches, and a high-polish chrome finish. It features two distinct end designs: the SUPERCOMBO open end uses specially designed grooves to direct wrenching force away from fastener corners, while the SUPERTORQUE box end applies force to the flat surfaces behind hex points rather than the corners themselves. This construction allows higher torque application without rounding or deforming the fastener. The wrench meets aerospace specification AS 954 for 12-point fasteners as defined by AS 870. It is used by professional mechanics, maintenance technicians, and tradespeople working on mechanical assemblies.

The JHW1216SC is suited for use on common hex (6-point) and 12-point fasteners in residential, commercial, and industrial maintenance settings. Both the box end and open end openings are identical in size, providing consistent fitment across fastener types. Its SUPERTORQUE box end design offers a measurable advantage over conventional box end wrenches for precision torque applications, making it well-suited for aerospace-grade and high-tolerance mechanical work where accurate torque-to-tension relationships are critical.

Installation Notes

This wrench is intended for use by qualified mechanics and tradespeople working on mechanical fasteners. Always ensure the wrench opening is fully seated on the fastener before applying torque. Inspect the wrench for wear or damage before each use, and do not use extension cheater bars that exceed the tool's intended load capacity. Follow applicable torque specifications provided by the equipment manufacturer.
