The DEWALT IMPACT READY 5-piece magnetic nut setter impact driver bit set multiplies your handyman abilities. It contains five nut setters of varying sizes for construction and DIY work. They screw wood, metal, and other materials together securely. The relatively small sizes let you access tight spaces in the grooves and nooks of the material. These are compatible with all impact drivers, as well as DEWALT Right Angle Attachments and Locking Bit Holders. They contain strong magnets that keep everything in place to make screwing and tightening easier. Everything is made of shock-resistant tool steel for maximum durability.
