Using the Klein Tools 631 nut driver set is a piece of cake. First, use the Tip-Ident feature to quickly pick the right nut driver for the job by looking at the color-coded handle ends. Then, firmly place the nut driver on the fastener and start turning. The cushion-grip handles give you a good hold and let you apply more torque comfortably. When working on long bolt applications, the full hollow shafts will come in very handy. As for maintenance, keep the nut drivers clean after each use. You can use a dry cloth to wipe off any dirt or debris. Store them in a dry place to prevent rusting. And be careful not to drop them from a high place, as it might damage the internal flanges or the shafts.
