Proto J3117M Open End Wrench 17 Mm Double End

Product Description

The PROTO J3117M is a double-end open end wrench sized at 17 mm, built for mechanical, HVAC, and plumbing trade work where a reliable hand tool is required for fastener access in tight or open spaces. Constructed from steel with a chrome-plated finish, this wrench provides corrosion resistance and durability through regular service use. The head features a 15-degree and 60-degree angle on opposing ends, giving the technician flexibility to approach fasteners from multiple positions. Weighing 0.2 pounds, the J3117M is a lightweight addition to any trade tool kit. It meets GGG-W-636E standards and carries a lifetime warranty from the manufacturer.

This wrench is suited for residential and light commercial mechanical work, including HVAC equipment installation and service, plumbing fixture connections, and general mechanical maintenance. The dual-head configuration allows a single tool to address fasteners from two distinct approach angles, reducing the need to reach for a second wrench in confined areas. It is appropriate for any trade professional who works with metric fasteners in the 17 mm range.
