Proto J3110M Open End Wrench 10 Mm Double End

Product Description

The PROTO J3110M is a double-ended open end wrench sized at 10 mm, built for professional hand-tool use in mechanical, industrial, and maintenance applications. The wrench is forged from steel with a chrome-plated finish that resists corrosion and simplifies cleaning in shop environments. Both ends feature offset head angles of 15 degrees and 60 degrees, giving technicians clearance options when working in tight or obstructed spaces. At 0.07 pounds, it is a lightweight tool suited for frequent use. The J3110M meets GGG-W-636E federal specification standards and carries a lifetime warranty from PROTO.

This wrench is used across automotive, HVAC, plumbing, electrical, and general mechanical service work wherever a 10 mm open end fitting is required. The dual-angle head design makes it practical for fastener access in confined areas such as equipment panels, engine bays, and mechanical rooms. It is intended for use by licensed technicians and experienced tradespeople who require a reliable, specification-grade hand tool for daily service work.
