Williams JHW1224YSC 3/4 Inch Combination Wrench Hi-vis Yellow

Product Description

The WILLIAMS COMFORT PRODUCTS JHW1224YSC is a 3/4 inch combination wrench built for professional fastener work in demanding trade environments. It features a SUPERCOMBO open end with machined grooves that redirect wrenching force away from fastener corners, reducing the risk of rounding. The SUPERTORQUE box end applies force to the flat surfaces behind the points rather than at the corners, allowing higher torque application without deforming hex fastener points. The wrench meets or exceeds aerospace specification AS 954 for 12-point fasteners and is finished in high-visibility yellow for quick identification in the field.

This combination wrench is suited for use across residential and commercial mechanical, HVAC, plumbing, and general industrial applications where both open-end and box-end access is needed on 3/4 inch fasteners. The SUPERTORQUE box end is compatible with all common 6-point hex fasteners in addition to 12-point applications, making it a flexible option for technicians who work across multiple system types. The matching box and open end openings simplify tool selection on the job.
