How do you install a self-drilling screw?

Make sure that the drill is fitted with a hex adapter (alternative adapters may be selected depending on the screw head type).Mark the surface / board at the point where the screw needs to be drilled & fastened.Fix the screw on the hex adapter and drill through the material.The drill bit end of the screw will pierce through the material and the threadings (on its body) will create a tapped hole for secure attachment.You can easily remove the installed screw using a drill, screw extractor or other hand tools.

Are self-drilling screws and self-tapping screws the same?

No, despite sounding quite the same and having a strong physical resemblance, both are two different types of screws. While the former features a pointed drill bit, at the screw end, that can drill into the material and cut its own thread, eliminating the requirement of a pilot hole, the latter is unable to drill through surfaces and need a pilot hole for tapping threads. Users should use self-drilling screws according to their most suitable applications and not interchangeably with self-tapping screws as that would result in a weaker joint between materials.
