The Tolsen 15259 is a seven-piece flexible gear spanner set designed to help you handle threaded fittings in tight installation spaces. This collection includes essential sizes from 8mm to 19mm, specifically 8, 10, 12, 13, 14, 17, and 19mm, ensuring you have the right fit for most common bolts. Each tool features a one-way ratcheting mechanism and a head that pivots 180 degrees, which allows you to maintain a grip and apply torque in hard-to-reach areas where a standard wrench cannot fit. Crafted from chrome vanadium steel, these spanners are built for durability and finished with a matte chrome plating that resists slips and wear. The set comes organized in a plastic holder, making it easy to keep your workspace tidy or hang the tools for quick access during a project.
