Self drilling screws are screws that have a drill bit tip at the end of the screw. They are designed to drill their own hole as they are screwed into a material, eliminating the need for pre-drilling. This makes them an ideal choice for fastening materials to metal, wood, or other hard surfaces. Self drilling screws are commonly used in construction, roofing, and woodworking applications. They are available in a variety of sizes, materials, and finishes to suit different applications. Some common types of self drilling screws include hex head, pan head, and flat heads
