This Klein Tools 3-piece set includes 3/8-inch power nut drivers made of high-impact rated S2 steel. These longer professional impact power bits are designed to easily reach into junction boxes and panels. The hex pockets feature minimal chamfering, which boosts the surface contact between the nut and the driver, ensuring better performance. The bits are color-coded according to the ASME standard for quick and easy identification. With a standard 1/4-inch (6.4 mm) hex shank, they are perfect for power impact drivers. Each bit comes with a strong magnet. You can also find these drivers, along with other sizes and tip bits, in the Pro Impact Power Bit Set with Case (Cat. No. 32799). Ideal for professional electricians, these impact-ready nut drivers offer maximum durability and efficiency.

Using these Klein Tools nut drivers is easy. Just insert the 1/4-inch hex shank into your power impact driver. They're great for quickly tightening or loosening nuts. When using, make sure your power impact driver is set to an appropriate speed for the job. As for maintenance, after each use, wipe the bits clean with a dry cloth to remove any dirt or debris. Store them in a dry place to prevent rusting. Don't use these bits for applications they're not designed for, as it could damage the bits or your equipment. Also, be careful not to over-tighten nuts, as it might wear out the bits faster. These bits are made to last, but with proper care, they'll serve you well for a long time.
