Frequently Asked Questions

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.
