The WILLIAMS TOOLS JHW1230RSC is a 15/16-inch 12-point SuperCombo combination wrench finished in high-visibility red. It combines a SuperTorque box end with a SuperCombo open end in a single tool. The box end applies wrenching force to the flat surfaces behind fastener points rather than the corners, reducing the risk of rounding or deforming hex fasteners under high torque. The open end features specially designed grooves that direct force away from fastener corners as well. Both the box and open end openings are identical in size, giving the technician two working ends at the same fastener dimension. This wrench meets or exceeds aerospace specification AS 954 for 12-point fasteners.
The JHW1230RSC is suited for mechanical, industrial, and maintenance applications where fastener integrity and tool accountability matter. The bright red finish supports tool management programs and color-coded work zone organization, making the wrench easier to locate in dirty, cluttered, or high-turnover environments. The 12-point box end is compatible with all common 6-point hex fasteners and provides a measurable torque advantage over conventional box end wrenches. It is used by mechanics, millwrights, pipefitters, and general maintenance technicians across commercial and industrial settings.
Designed as a 15/16-inch combination wrench for use on 12-point and standard 6-point hex fasteners in mechanical, industrial, and maintenance applications.
This wrench is a hand tool intended for use by qualified mechanics and maintenance technicians. Before loosening or tightening fasteners on pressurized systems, powered equipment, or energized assemblies, follow all applicable lockout/tagout procedures per OSHA and site safety requirements. Select the correct fastener size before applying torque to avoid slippage or fastener damage. Inspect the wrench for cracks or deformation before each use and remove from service if damage is found.
