Williams Comfort Products JHWEWM-1011 Open End Wrench 10x11mm

Product Description

The WILLIAMS COMFORT PRODUCTS JHWEWM-1011 is a double-ended open end wrench designed for fastener work in tight or open access situations. It features a 10 MM opening on one end and an 11 MM opening on the other, giving technicians two sizes in a single tool. The overall length is approximately 5.3 inches and the wrench weighs 0.1 pounds. A satin-chrome finish reduces glare, resists corrosion, and wipes clean quickly between jobs. The continuous arc jaw design resists spreading under load and is structurally stronger than open V designs. Each wrench end carries a 45-degree chamfer that simplifies seating the tool on a fastener in confined spaces. This wrench meets ANSI B107.9M standards.

This wrench suits trade professionals working on HVAC equipment, plumbing connections, gas line fittings, and general mechanical assemblies where metric fasteners are present. The dual-size format is practical for service calls where carrying a full wrench set is inconvenient. The compact overall length of 5.3 inches makes it workable in areas with limited swing clearance. Plumbers, HVAC technicians, and mechanical contractors will find the metric sizing relevant to imported equipment, mini-split systems, and European-origin components.

Installation Notes

This wrench is a hand tool requiring no installation. Always select the correct jaw size for the fastener to avoid rounding hardware. Shut off system power and close relevant supply valves before servicing any equipment the wrench is used on. Inspect the wrench for cracks or jaw spread before each use and replace if deformation is observed.
