5. Corrosion Resistance Many self-drilling screws are coated or made from stainless steel to resist rust and corrosion. This makes them ideal for outdoor use or in environments where moisture is present.

In addition to their self-drilling feature, these screws also come with various security enhancements to prevent tampering. For example, some self-drilling security screws are made with a unique head design that requires a special tool, such as a security bit or driver, to tighten or loosen. This makes it nearly impossible for someone without the proper tool to remove the screws, adding an extra layer of security to the installation.
