Using this Klein Tools 630 - 1/2 nut driver is easy. First, identify the nut size you need to work on. The color - coded handle end and Tip - Ident® will help you pick the right one quickly. Then, grip the cushion - grip handle firmly to apply the necessary torque. This handle is designed to give you more comfort and better control. When using it on stacked circuit boards or long bolts, the full hollow shaft allows you to work smoothly. Just make sure to align the nut driver properly with the nut. As for maintenance, since it's chrome - plated, it has good corrosion resistance. But after each use, it's a good idea to wipe it clean with a dry cloth to keep it in good condition. Avoid using it in wet or extremely corrosive environments as it's not insulated. Also, don't apply excessive force that could damage the internal flanges or the shaft. With proper use and care, this nut driver will serve you well for a long time.
