Self Drilling Screws, Also Known as TEK Screws, Drill Point, Self Drillers and Self Tapping
Self Drilling Screws are used primarily when fastening into steel or other metals and are typically used to join materials like sheet metal.
Point Wings are used on some screws that fasten thicker materials, such as wood, to metal. The wings enlarge the hole in the fastened material, allowing the threads to pass through without contacting the fastened material. This added clearance prevents separation of the fastened material from the base metal (known as "jacking"). The wings will break away on contact with the metal before the threads engage in the metal..
