Using the Klein 5/16 Magnetic Nut Driver is easy. First, pick the right nut with the 5/16 - sized driver. The magnetic tip will hold the nut in place, so you don't have to worry about it falling off. When working on stacked circuit boards or long - bolt applications, the hollow shaft design lets the bolt pass through without any issues. Hold the Cushion - Grip handle firmly for better torque and comfort. The color - coded end makes it easy to grab the right tool in a hurry. As for maintenance, keep it clean after each use. Wipe off any dirt or debris with a dry cloth. Avoid using it in wet conditions as it's not insulated. If the magnetic strength seems to fade over time, you can try re - magnetizing it with a magnet. Store it in a dry place to prevent corrosion, thanks to the chrome plating it won't rust easily, but it's always good to take extra care.
