Williams Comfort Products JHW8723 Box End Wrench 3/8x7/16 in

Product Description

The WILLIAMS COMFORT PRODUCTS JHW8723 is a 12-point offset box end wrench with 3/8-inch and 7/16-inch openings, built for professional trade use in tight fastener applications. The SUPERTORQUE box opening geometry applies wrenching force to the flat surfaces of the hex fastener rather than the corners, reducing the risk of rounding or deforming fastener points under high torque. The 60-degree offset profile adds clearance for knuckles and bolt heads in confined spaces. Size markings are stamped on the handle ends for quick identification in a tool bag or on a service truck.

This wrench is suited for HVAC technicians, plumbers, electricians, and general mechanical tradespeople working on equipment, pipe fittings, valve stems, and structural fasteners where a standard open-end wrench cannot apply sufficient torque or lacks the access angle needed. The offset design is especially useful when working around panels, flanges, or closely spaced components where a straight wrench would bind against adjacent surfaces.

Key Features

• SUPERTORQUE 12-point box opening applies force to flat fastener surfaces, not corners, reducing deformation risk
• 60-degree offset box end provides extra knuckle clearance and bolt head clearance in confined spaces
• Dual-size wrench: 3/8-inch opening on one end, 7/16-inch opening on the other
• Size markings on handle ends for fast identification
• Meets ANSI B107.6 federal specification

Compatibility

Designed for use with standard 3/8-inch and 7/16-inch hex fasteners in residential and commercial trade service applications.

Installation Notes

This wrench is a hand tool requiring no installation. Ensure the correct opening size is seated fully on the fastener before applying torque to prevent slippage. When working near energized electrical components, de-energize the circuit and follow applicable NEC lockout/tagout procedures before using any hand tool in the work area. Do not use a cheater bar or pipe extension to increase leverage beyond the tool design.
