The Tolsen 20068 is a folding set of eight ball point hex keys designed for working with threaded fittings and various installation tasks. These tools are forged from high-quality Chrome Vanadium steel and have undergone heat treatment to ensure they remain strong and durable under pressure. To protect against corrosion, each key is finished with a matte chrome plating. This compact set includes sizes ranging from 1.5mm to 8mm, all housed within a foldable holder that keeps them organized and easy to carry. The ball point tips are particularly useful for those tight spots where you need to access a screw at an angle, making it a practical choice for anyone performing maintenance or assembly work.
