Fas-n-Tite #7 x 7/16-in Phillips -Drive Self-tapping Sheet Metal Screws 356 -Count

Self-drilling screws allow drilling and fastening to be done in the same motion. This self-drilling screw is used in wood, fiberglass, and metal, and it features a drill point enabling it to drill its own hole in thin gauge steel. The sharp threads create their own mating thread when drilled into the material. No pre-drilled pilot holes are necessary. These screws are phosphate coated for rust and corrosion resistance.
