Self-drilling screws are fasteners that drill their own hole when driven into an object. They feature a head, shank, and a drill-like curved tip that mimics a drill bit's function, allowing them to drill into objects while tapping their own threads without needing a pilot hole. They come with different head types like hexagonal or Phillips head and varying lengths.

These screws are versatile fasteners used for joining various materials. They can attach wood to wood, metal to metal, and metal to wood, making them ideal for lightweight materials. Common applications include metal roofing, HVAC ductwork, steel frames, woodworking tasks like shed construction, and plastic piping work.
