Williams Comfort Products JHWEWM-1618 Open End Wrench 16x18mm

Product Description

The WILLIAMS COMFORT PRODUCTS JHWEWM-1618 is a metric open end wrench with 16 MM and 18 MM openings, built for professional fastener work in mechanical, HVAC, plumbing, and general trade applications. The wrench features a continuous arc jaw design that resists spreading under load, making it more durable than traditional OVO-style construction. A 45-degree chamfer on each wrench end allows fast, accurate placement onto fasteners in tight spaces. The satin-chrome finish reduces glare, provides a secure grip, and wipes clean between uses. Overall length is 8.5 inches and the unit weighs 0.33 pounds.

This wrench is suited for residential and light commercial service work where metric fasteners are standard. Common applications include equipment service panels, hydronic heating components, refrigeration line fittings, and pump or valve assemblies. The dual-opening design covers two fastener sizes in a single tool, reducing the number of wrenches a technician carries on a service call. It is sold individually and is a practical addition to any trade tool kit requiring metric coverage.

Installation Notes

This wrench is a hand tool requiring no power source or specialized installation procedure. Ensure the correct jaw size is fully seated on the fastener before applying torque to avoid rounding.
