1. Ease of Use The hexagonal shape allows for better grip, enabling users to apply more torque without slipping.

4. Corrosion Resistance Mechanical fasteners often create points of vulnerability where corrosion can occur, especially when dissimilar materials are joined. Bonded fasteners provide a continuous seal that can prevent moisture intrusion, thereby reducing the risk of corrosion and extending the lifespan of the assembly.

The self-drilling aspect of these screws implies that they come equipped with a sharp, drill-like tip that enables them to pierce through materials without the need for pre-drilling a pilot hole. This feature significantly speeds up the installation process and reduces the risk of damaging the material being used. Self-drilling screws are often made from durable materials, such as stainless steel or carbon steel, and are coated with various finishes to enhance corrosion resistance and longevity.
