Williams Comfort Products JHW1244B Combination Wrench 1 3/8 in

Product Description

The WILLIAMS COMFORT PRODUCTS JHW1244B is a combination wrench with a 1 3/8 inch opening, built for industrial and professional fastener work. It features a SUPERTORQUE box end that contacts the flat surfaces of hex fasteners rather than the corners, allowing higher torque application without rounding or deforming fastener points. The SUPERCOMBO open end uses specially designed grooves to direct wrench force away from fastener corners as well. Both the box end and open end share identical opening sizes, giving technicians consistent sizing across both ends. The wrench carries an industrial black finish and meets ANSI B107.6 and SAE AS 954 specifications.

This wrench is suited for industrial maintenance, mechanical assembly, and heavy-duty trade work where fastener integrity matters. 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 is also compatible with all common 6-point hex fasteners, offering an advantage over conventional box end wrenches in both flexibility and service economy. Typical users include industrial mechanics, aerospace technicians, and experienced trade professionals working in demanding fastener environments.
