Self drilling roofing screws are a commonly used variety of screw for quick drilling into both metal and wood. A self drilling roofing screw can typically be identified by its point and flute (notch) tip. This tip acts as a drill bit for the screw making it much faster to install then having to switch between a drill bit and driver bit.

Self drilling roofing screws are almost always made out of hard steel or some metal that has been treated to increase its hardness (such as 410 stainless steel). Always make sure when using self drilling screws, the material you drill into is softer than the screw material itself. Otherwise, the screws drilling tip will dull and not cut into the material. All self drilling roofing screws are also self tapping by the nature of how they work.
