Williams JHW1236YSC Combination Wrench 1-1/8 in Hi-vis Yellow

Product Description

The WILLIAMS COMFORT PRODUCTS JHW1236YSC is a 1-1/8 inch combination wrench finished in Hi-Vis Yellow, designed for trade professionals who require precision torque application on hex fasteners. The open end uses a SUPERCOMBO groove design that redirects wrenching force away from fastener corners, reducing the risk of rounding. The box end uses a SUPERTORQUE 12-point design that contacts the flat surfaces behind fastener points rather than the corners, allowing higher torque without deforming the fastener. Both openings measure identically at 1-1/8 inch, giving technicians consistent sizing across both ends.

This wrench is suited for mechanical, HVAC, plumbing, and electrical trade work where fastener integrity matters. The SUPERTORQUE box end meets aerospace specification AS 954 for 12-point fasteners as defined by AS 870, making it appropriate for precision torque and tension applications. The SUPERCOMBO open end provides a meaningful advantage over conventional open-end designs on standard 6-point hex fasteners, increasing flexibility in tight or awkward installation scenarios. The Hi-Vis Yellow finish aids tool visibility on busy job sites.

Compatibility

Designed for use on standard 6-point and 12-point hex fasteners with a 1-1/8 inch opening. Suitable for general mechanical and trade applications requiring a combination wrench in this size.

Installation Notes

This wrench is a hand tool requiring no power source or special licensing to use, but should be applied by qualified trade personnel familiar with fastener torque requirements for the application at hand. Always confirm the correct wrench size before applying torque to avoid fastener damage. Inspect the wrench for cracks or deformation before each use and do not use extension bars or cheater pipes on combination wrenches not rated for such use.
