1. Hexagonal flange head: the head of the screw is a hexagonal shape with a flange, and the hexagonal shape is easy to use a tool (such as a wrench or sleeve) to tighten or loosen; The flange acts like a gasket, dispersing the fastening pressure, reducing damage to the fixing material and providing better fastening force.

2. Self-drilling point: The tip of these screws is designed to resemble the shape of a drill bit, and can be cut and formed by itself without pre-drilling, thus saving installation time and additional processes.

3. Versatility: Combined with the characteristics of self-tapping screws and self-drilling screws, hexagonal flange head self-drilling screws are suitable for a variety of materials and applications, and can be widely used in metal roofs, building metal frames and other quick fastening occasions.

4. Corrosion resistance: These screws are usually surface treated (such as galvanized or painted) to enhance corrosion resistance, so that they can be used outdoors or in harsh environments.

5. High efficiency: Due to their self-drilling characteristics, no additional drilling steps are required during installation, greatly improving operational efficiency.

6. Good fastening effect: Because the flange is wide, they provide better load distribution and fastening effect, effectively avoiding the phenomenon of fasteners pulling through.
