Williams JHW1240YSC Combo Wrench 1 1/4 Inch Hi-vis Yellow

Product Description

The WILLIAMS COMFORT PRODUCTS JHW1240YSC is a 1 1/4 inch combination wrench built for trade professionals who demand precise torque control and fastener protection. The open end uses a SUPERCOMBO profile with machined grooves that redirect wrenching force away from fastener corners, reducing rounding on worn or soft hex heads. The box end features a SUPERTORQUE 12-point design that contacts flat surfaces behind the points rather than the corners, allowing higher torque application without deforming the fastener. The wrench is finished in Hi-Vis Yellow for fast identification in a crowded toolbox or job site.

This wrench suits licensed technicians and trade professionals working in HVAC, plumbing, mechanical, and industrial maintenance applications where accurate torque is required. The 12-point box end meets aerospace specification AS 954 for 12-point fasteners as defined by AS 870, making it appropriate for precision torque applications beyond typical hand-tool work. The open end and box end openings are both sized at 1 1/4 inch, so both ends engage the same fastener size without switching tools. The wrench is sold individually.
