Crown Bolt 34552 #10 x 3/4 Inch Stainless Steel Pan-Head Phillips Sheet Metal Screws, 25-Count
Also known as self-tapping screws, sheet metal screws are highly versatile. Used in wood, fiberglass, and metal, the self-drilling screw possesses a drill point enabling it to drill in its own hole in light gauge steel. The sharp threads create their own mating thread when drilled into the material. No pre drilled holes necessary.
