Irwin IWAF242516 1-7/8IN X 5/16IN MAG NUT DR - 1 PACK

Lobular design reduces stripping damage by driving the fastener on the sides instead of forcing the corners to turn. Maintains the true shape of the fastener, dramatically reducing breakage and stripping damage. Provides more clearance on the corners of the fastener where paint build-up can occur. Magnetic nutsetters use magnets that are 4X more powerful than common magnets. Positive retention of the screw improves installation rate. Universal 1/4 in hex shank fits most power tools and quick-change chuck Adapters. For sheet metal screws and other hexagonal head fasteners.
