Description Ever stuck a screw in your impact driver while installing solar, only to have the screw fall out and roll down the roof? We’ve been there. Most hex driver bits rely on a magnet to hold the screw in. Problem is, quality solar fasteners are made of 304 stainless steel– which is not magnetic! We’ve got you covered with this nonmagnetic nutsetter. It uses a clever mechanism consisting of a spring and a ball bearing to securely grip any hex-head screw– stainless or otherwise. You can really shake this thing around and the screw will not come out. Features: Comes in two sizes – 5/16″ and 3/8″ Compatible with impact drivers and drills
