Phillips Flat Head Sheet Metal Screw

Sheet metal screws have sharp threads that cut into a material such as sheet metal, plastic or wood. They are sometimes notched at the tip to aid in chip removal during thread cutting. The shank is usually threaded up to the head. 316 stainless steel uses additional amounts of nickel and molybdenum for increased resistance to chlorides and sulfates (salts, salt water) and often used in food processing, marinas, photographic works, chemical refineries, and other manufacturing.
