2. Versatility Hex head self-drilling screws are designed for use in a variety of materials, making them highly versatile. They are commonly used in metal roofing, siding, and other metal-to-metal applications, as well as in wood and plastic. Their ability to fasten dissimilar materials together makes them ideal for a wide range of projects, from residential to commercial construction.

At its core, the structure of a bolt consists of a few key components the head, the shank, and the threads. The head is the larger, often hexagonal or square part at one end of the bolt, designed to provide a surface for the application of torque when tightening or loosening the bolt with a wrench. The shank is the long cylindrical part that spans between the head and the threads, and it determines the overall length of the bolt. The threads are helical ridges that spiral around the shank, allowing the bolt to engage with a nut or a threaded hole, enabling a strong clamping force between joined parts.

5. Corrosion Resistance Many 2% self-drilling screws are treated with coatings, such as zinc plating or epoxy, to enhance their resistance to rust and corrosion. This feature makes them suitable for outdoor applications and environments exposed to moisture.
