Sheet Metal Screws
Sheet Metal Screws / Tapping Screws are threaded fasteners with the unique ability to "tap" their own mating internal thread when driven into preformed holes in metallic and non-metallic materials. Sheet Metal screws / Tapping Screws are high strength, one-piece, one-side installation fasteners. Because they form or cut their own mating thread, there is unusually good thread fit, which enhances resistance to loosening in service. Sheet Metal Screws / Tapping Screws can be disassembled and are generally reusable
