Using this Klein 12-piece L-style hex key set is a breeze. First, pick the right-sized hex key from the caddy for your job. The long side is great for reaching tight spots, while the short side gives you more torque when you need it. When using the keys, apply steady pressure and turn in the right direction. As for maintenance, keep the keys clean after each use. You can wipe them with a dry cloth. If they get dirty, use a mild cleaner and dry them thoroughly. Store the set in the caddy to protect the keys and keep them organized. And always handle the keys carefully to avoid any damage.
