Williams Comfort Products JHW7731B Box End Wrench 12-point

Product Description

The WILLIAMS COMFORT PRODUCTS JHW7731B is a 12-point offset box end wrench with a 13/16 x 7/8 inch dual opening, built for professional trade use in tight, high-torque fastening situations. The SUPERTORQUE box opening geometry transfers wrenching force onto the flat surfaces of the fastener rather than its corners, reducing the risk of rounding or deforming hex fastener points under load. The 10-degree offset box end provides the clearance needed to work in confined spaces where a standard wrench cannot gain a full swing. Sizes are stamped on the handle ends for fast identification in a toolbox or service bag.

This wrench suits licensed mechanics, pipefitters, HVAC technicians, plumbers, and electricians who regularly work with hex fasteners in restricted access areas. The dual-opening design gives two size options in a single tool, making it practical for service calls where reducing the number of hand tools carried matters. It is sold individually and is appropriate for both residential and light commercial service applications where fastener integrity and torque control are priorities.

Installation Notes

This wrench is a hand tool requiring no power source or special installation. Before applying torque to any fastener in a live system, shut off power, gas, or fluid supply as applicable to the service task. Inspect the wrench for cracks or deformation before use and do not use a cheater bar or extension on the handle, as this can exceed the tool's design load and damage fasteners.
