Using this Klein Tools TORX T - Handle Hex Key Set is a breeze. First, select the right hex key from the set according to the size you need. You can easily identify the size thanks to the laser - etched markings on the blade. Hold the T - handle with a firm grip. The soft - touch surface will make it comfortable and give you good control while you turn the key. For high - torque applications, the blade - through - handle design is there to help. When you're done using the tools, place them back in the metal stand to keep them organized. You can also use the hang hole to hang the stand on a wall for convenient storage. As for maintenance, since the tools are made of treated steel, they're resistant to rust and corrosion. But it's still a good idea to wipe them down after use to keep them in top condition. Avoid using excessive force that could damage the keys, especially when dealing with very tight fasteners.
