Self-drilling screws are equipped with a cutting point at their tip, which functions like a drill bit, allowing them to pierce through metal, wood, or plastic effortlessly. This eliminates the need for a separate drilling process, thereby saving time and increasing productivity on the job site. The threads on the screw's body then engage with the substrate material, providing a secure hold, and preventing any slippage or loosening over time.
