Williams JHW1220YSC 5/8 Inch Combination Wrench Hi-vis Yellow

Product Description

The WILLIAMS COMFORT PRODUCTS JHW1220YSC is a 5/8-inch combination wrench designed for professional trade use where both speed and torque precision matter. The open end features a SUPERCOMBO design with specially engineered grooves that redirect wrenching force away from fastener corners, reducing the chance of rounding. The box end uses a SUPERTORQUE design that contacts the flat surfaces behind fastener points rather than the corners themselves, allowing higher torque application without deforming the fastener. The wrench is finished in Hi-Vis Yellow for quick identification in a busy work environment. It meets or exceeds aerospace specification AS 954 for 12-point fasteners as defined by AS 870.

The JHW1220YSC is suited for mechanical, HVAC, plumbing, and electrical trade work wherever 5/8-inch hex fasteners are encountered. Both the box end and open end share an identical 5/8-inch opening, giving the technician flexibility depending on access and torque requirements. The SUPERTORQUE box end is compatible with all common 6-point hex fasteners and provides a measurable advantage over conventional box end wrenches in tight-tolerance applications. Meets Federal Specification ANSI B107.6.
