Williams JHW1212YSC Combination Wrench 3/8 Inch Hi-vis Yellow

Product Description

The WILLIAMS COMFORT PRODUCTS JHW1212YSC is a 3/8-inch combination wrench built for trade professionals who need reliable torque performance on hex fasteners. It features two distinct end designs: the SUPERCOMBO open end uses specially machined grooves to redirect wrench force away from fastener corners, reducing the risk of rounding. The SUPERTORQUE box end applies wrenching force to the flat surfaces behind fastener points rather than the corners, allowing higher torque without deforming the fastener. The Hi-Vis Yellow finish makes the tool easy to locate on a crowded job site. Both openings are identically sized at 3/8 inch.

This combination wrench suits a wide range of commercial and residential trade applications including HVAC, plumbing, and general mechanical work. The SUPERTORQUE 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. The SUPERCOMBO open end works on all common 6-point hex fasteners and provides a meaningful advantage over conventional open-end designs, improving both flexibility and tool economy on the job.
