Williams Comfort Products JHW628SC Combination Wrench 7/8 in

Product Description

The WILLIAMS COMFORT PRODUCTS JHW628SC is a combination wrench with a 7/8-inch opening, built for professional fastener work in mechanical, HVAC, and plumbing service applications. The wrench features two distinct end designs: an open end engineered with directional grooves that shift wrenching force away from fastener corners, and a 6-point box end with a SUPERTORQUE profile that applies force to the flat surfaces of the hex rather than the points. This reduces the risk of rounding or deforming fasteners under high torque. The chrome finish is polished and textured for a secure grip and easy cleaning. The wrench weighs 1.04 pounds and spans 12.25 inches in length.

The JHW628SC is suited for use in residential and light commercial service environments where 7/8-inch fasteners are common, including HVAC equipment panels, pipe fittings, and mechanical assemblies. The combination design gives technicians the flexibility of both open-end and box-end access in a single tool, making it practical for tight-clearance service calls where switching tools slows the job down.

Key Features

• SUPERTORQUE 6-point box end applies force to fastener flats, not corners, reducing deformation risk under high torque
• Open end grooves direct wrenching force away from fastener corners for improved grip on worn or tight fasteners
• 7/8-inch opening fits standard imperial hex fasteners common in HVAC and mechanical applications
• High-polish chrome textured finish resists smudging and wipes clean with minimal effort
• Single-piece combination design eliminates the need to carry separate open-end and box-end wrenches

Compatibility

Designed for use with 7/8-inch imperial hex fasteners in trade service applications including HVAC, plumbing, and general mechanical work.

Installation Notes

This wrench is used by HVAC technicians, plumbers, and mechanical service professionals. Before servicing any equipment, shut off power and close all relevant isolation valves or disconnect switches in accordance with applicable safety procedures. Use the box end when maximum torque is required and access allows full engagement; use the open end for faster rotation in open areas. Inspect the wrench for cracks or deformation before each use and do not use it as a hammer or extension lever.
