These screws feature small wing-like extensions between the threads and the drill point. The wings help enlarge the hole when drilling through softer materials (e.g., wood), preventing the material from rising or getting damaged as the screw passes through. Once the wings hit the metal surface, they snap off, allowing the drill point to penetrate the metal cleanly.
 
The screw has a built-in drill tip that eliminates the need for pre-drilling, making the installation faster and more efficient. The tip is designed to cut through metal and other harder substrates, ensuring a tight and secure fastening.
