Drywall screws are usually bugle head screws with spaced threads and sharp points. Classified by the pitch of thread, there are two common kinds: fine thread and coarse thread.

  • Fine Thread: Sharper points for easier entry, commonly used for light metal studs.
  • Coarse Thread: Fewer threads for a tighter hold and faster installation, ideal for wood studs.
  • Self-Drilling: Designed for heavy metal studs, eliminating the need for pre-drilled holes.
