Self drilling screws have an integrated drill point that allows for a quick transition from drilling to tapping and eliminates the need for a pilot hole. These have a hex head with a built in washer and are typically used in metal, wood, or fiberglass. They are made of superior rust resistant 410 stainless steel that has been hardened. They have a black oxide finish. 410 stainless steel is mildly magnetic and can be used for hands free installation with a magnetic driver bit.
