Williams Comfort Products JHW8731A Box End Wrench 3/4 X 7/8

Product Description

The WILLIAMS COMFORT PRODUCTS JHW8731A is a 12-point offset box end wrench with a 3/4 inch by 7/8 inch opening, built for trade professionals who need reliable torque application in confined spaces. The SUPERTORQUE box opening design contacts the flat surfaces of the fastener behind the points rather than at the corners, allowing higher torque to be applied without rounding or deforming hex fastener points. The 60-degree offset box end provides extra knuckle clearance and bolt clearance when working in tight areas. Weighing 0.63 pounds and measuring 12 inches in length, this wrench is a practical hand tool for HVAC, plumbing, and general mechanical service work.

This wrench is suited for residential and commercial service applications where access to fasteners is restricted by surrounding components or structures. The 60-degree offset geometry makes it especially useful in equipment cabinets, mechanical rooms, and under-counter installations where a standard straight wrench cannot achieve adequate swing. Size markings on the handle ends allow quick identification when multiple wrenches are in use. It is sold individually and is appropriate for any trade professional working with standard hex fasteners in the 3/4 inch and 7/8 inch range.

Key Features

• SUPERTORQUE 12-point box opening applies wrenching force to flat fastener surfaces, not corners, reducing the risk of rounding fastener heads
• 60-degree offset provides extra knuckle clearance and bolt clearance in restricted work areas
• Dual-size opening: 3/4 inch on one end, 7/8 inch on the other
• Size markings stamped on handle ends for fast identification
• Meets ANSI B107.6 federal specification

Compatibility

Designed for use with standard hex fasteners in 3/4 inch and 7/8 inch sizes across HVAC, plumbing, and general mechanical service applications.

Installation Notes

This wrench is used by licensed HVAC technicians, plumbers, pipefitters, and general mechanical tradespeople. Ensure the correct opening size is fully seated on the fastener before applying torque to prevent slippage. When working near energized components or pressurized lines, follow applicable lockout/tagout and system isolation procedures before using hand tools in the work area.
