The WILLIAMS COMFORT PRODUCTS JHW1188B is a combination wrench with a 1 7/8 inch opening designed for industrial and professional fastener work. It features a SUPERTORQUE box end and a SUPERCOMBO open end, both machined to identical opening sizes. The SUPERTORQUE box end applies wrenching force to the flat surfaces of hex fasteners rather than the corners, reducing the risk of rounding or deforming fastener points under high torque. The SUPERCOMBO open end uses specially designed grooves to direct force away from fastener corners as well. This wrench is sold as a single unit and suits licensed tradespeople, maintenance mechanics, and industrial technicians working with heavy-duty fasteners.
The JHW1188B is suited for industrial maintenance, construction, and mechanical service applications where large hex fasteners are encountered. Its identical box and open end openings allow technicians to switch between drive styles without changing tools. The 12-point 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 where fastener integrity is critical. The open end configuration also provides considerable advantage over conventional box end wrenches on standard 6-point hex fasteners.
Designed for use on 1 7/8 inch hex and 12-point fasteners across industrial, mechanical, and maintenance applications. Conforms to ANSI B107.6 and Federal Specification SAE AS 954.
This wrench is installed and operated by hand without power tools. Always ensure the wrench opening is fully seated on the fastener before applying torque. Inspect the wrench for cracks or deformation before each use and remove from service if damage is found. Work in compliance with applicable workplace safety standards when working on pressurized or energized systems.
