Williams Comfort Products JHW1248B Combination Wrench

Product Description

The WILLIAMS COMFORT PRODUCTS JHW1248B is a 12-point combination wrench with a 1-1/2 inch opening, built for professional-grade fastener work in industrial and mechanical applications. The box end uses a SUPERTORQUE design that places wrenching force on the flat surfaces of the fastener rather than the corners, reducing the risk of rounding or deforming hex points under high torque. The open end features SUPERCOMBO geometry with grooves that redirect force away from fastener corners as well. Both the box end and open end share identical opening sizes, giving the technician consistent tool engagement on either side.

This wrench is suited for industrial maintenance, heavy equipment repair, and precision assembly work where fastener integrity matters. It meets or exceeds aerospace specification AS 954 for 12-point fasteners as defined by AS 870, making it appropriate for precision torque applications requiring an accurate torque-to-tension relationship. It is compatible with all common 6-point hex fasteners as well, offering flexibility across a wide range of fastener types. The industrial black finish provides durability in shop and field environments. It conforms to ANSI B107.6 and SAE AS 954 federal specifications.
