Williams Comfort Products JHW1220BSC Combination Wrench 5/8 in

Product Description

The WILLIAMS COMFORT PRODUCTS JHW1220BSC is a 5/8-inch combination wrench built for professional and industrial use. It features a SUPERCOMBO open end and a SUPERTORQUE box end, both with identical opening sizes. The SUPERTORQUE box end applies wrenching force to the flat surfaces behind fastener points rather than at the corners, reducing the risk of rounding or deforming hex fasteners under high torque. The SUPERCOMBO open end uses specially designed grooves to redirect force away from fastener corners. This wrench meets or exceeds aerospace specification AS 954 for 12-point fasteners as defined by AS 870, making it suitable for precision torque applications in demanding environments.

This combination wrench is intended for use in industrial, aerospace, and general mechanical applications where both hand tool flexibility and fastener integrity are priorities. It is compatible with all common 6-point hex fasteners as well as 12-point fasteners, offering a clear advantage over conventional box end wrenches in tight or repetitive service situations. Licensed technicians and skilled tradespeople in mechanical, aerospace, and heavy equipment fields will find this wrench appropriate for daily professional use.
