The Tolsen 20056 is a 9-piece Torx long arm hex key set designed for working with Torx fixing screws in both home and professional settings. These tools are crafted from heat-treated chrome vanadium steel, which ensures they remain strong and reliable during repeated use. To protect against corrosion and provide a clean look, each key features a satin chrome plated finish. This set includes a comprehensive range of sizes, from T10 up to T50, covering the most common requirements for mechanical and assembly tasks. The long arm design provides you with better reach into deep recesses and increased leverage, making it easier to loosen stubborn fasteners with less effort.
