Using your Klein 2.5 mm L - Style Ball - End Hex Key is a breeze. When you need to reach tight spots, use the long side of the key. For jobs that require more force, the short side is your go - to. The ball end can be used at angles up to 25 degrees, which gives you more flexibility. Just insert the key into the socket and turn it in the appropriate direction. As for maintenance, keep your hex key clean after each use. You can use a dry cloth to wipe off any dirt or debris. Store it in a dry place to prevent rusting. Also, avoid using it on sockets that are too big or small for the 2.5 mm size, as this could cause damage to the key or the socket.
