Sheet metal screws have sharp threads, sometimes referred to as self cutting or self threading screws, that cut into sheet metal, such as aluminum, plastic or wood. Some sheet metal fasteners are classified as Type 17 Point, these screws are notched at the tip to aid in chip removal during thread cutting. Sheet metal screws as also known as self tapping screws because they self tap into the material they are being screwed into. Self driller cutting points, also known as TEK screws available in TEK 2, 3, 4 and 5, pierce through 20 to 14 gauge metals. The higher the TEK number the larger the drill point to pierce heavier gauge metals.
