The Tolsen 20053 is a 9-piece ball point long arm hex key set designed for both home maintenance and professional mechanical work. Each key is crafted from heat-treated chrome vanadium steel with a chrome plating, which helps the tools resist wear and corrosion over time. The set includes a comprehensive range of sizes, from 1.5mm up to 10mm, ensuring you have the right fit for various fasteners. A standout feature of these keys is the ball point on the long arm, allowing you to engage screws at a 30-degree angle. This makes it much easier to reach bolts in tight or awkward spaces where a straight-on approach is impossible. The tools come organized on a blister card, making them easy to store and keep track of in your toolbox.
