Proto J31011 Open End Wrench 10 Mm X 11 Mm Double End

Product Description

The PROTO J31011 is a double-ended open end wrench sized at 10 mm and 11 mm, built for professional use in mechanical, HVAC, plumbing, and electrical service work. The wrench is manufactured from steel with a satin finish that reduces glare and resists corrosion in field conditions. A 15-degree head angle offsets the jaw from the handle, allowing the tech to reposition the wrench in tight clearance spaces without fully withdrawing it from the fastener. At 0.13 pounds, it is a compact, lightweight hand tool suited for close-quarter fastener work on equipment panels, brackets, and fittings.

This wrench is intended for use wherever 10 mm or 11 mm hex fasteners are encountered. Common applications include HVAC equipment access panels, electrical enclosure hardware, conduit fittings, and mechanical assemblies in both residential and light commercial settings. The double-ended design eliminates the need to carry two separate wrenches for adjacent metric sizes, making it a practical choice for service techs working out of a tool bag or service van.

Installation Notes

This wrench is a general-purpose hand tool used by HVAC technicians, plumbers, electricians, and mechanical service professionals. Always de-energize electrical equipment and shut off gas or fluid supply lines before performing fastener work on live systems. Apply force in the pulling direction when possible to reduce the risk of slipping off the fastener. Inspect the wrench jaw for wear or damage before use, and do not use a wrench as a striking tool or apply extensions to the handle.
