Proto J3113M Open End Wrench 13 Mm Double End

Product Description

The PROTO J3113M is a double-ended open end wrench sized at 13 mm, built for fastener work in mechanical, HVAC, plumbing, and electrical trade applications. Constructed from steel with a chrome-plated finish, it delivers corrosion resistance and durability in demanding shop or field conditions. The double-end head configuration features 15-degree and 60-degree head angles, giving technicians added versatility when working in tight or offset clearances. At 0.12 pounds, it is a lightweight hand tool suited for both bench work and on-site service calls.

This wrench is appropriate for residential and commercial trade work wherever 13 mm fasteners appear — common in HVAC equipment panels, piping systems, electrical enclosures, and light mechanical assemblies. The dual head angles allow access to fasteners at varying orientations without switching tools, which is useful during equipment installation, maintenance, or repair where access is restricted. It meets GGG-W-636E standards, confirming performance and dimensional conformance for professional use.
