Using the Klein Tools 646 - 1/4 nut driver is easy. First, identify the nut you need to work on. The color - coded handle end and Tip - Ident® will help you quickly pick the right tool. Just place the tip of the driver on the nut and start turning. The Cushion - Grip handle gives you extra torque, so you don't have to use too much force. When working on stacked circuit boards or with extra - long bolts, the hollow shaft allows you to get right in there. As for maintenance, keep it clean. After use, wipe it down with a dry cloth to remove any dirt or debris. Since it's chrome - plated, it has some corrosion resistance, but try to avoid leaving it in damp places. Also, make sure to store it in a safe place where it won't get damaged. And always remember, it's not insulated, so don't use it in electrical applications where insulation is required.
