Self-tapping screws and self-drilling screws are both types of screws that are designed for specific types of materials and applications.
The main difference between the two is the type of tip that they have. Self-tapping screws have a sharp, pointed tip that is designed to cut threads into the material as the screw is being installed, while self-drilling screws have a drill-like tip that is
used to create a hole in the material as the screw is being installed. This allows self-drilling screws to be used in materials that are too hard or dense to be tapped conventionally, such as metal or plastic. Both self-tapping and self-drilling screws can be used to fasten two materials together, but the type of screw that is used will depend on the specific materials and application.
