A Pan Head Self-Drilling Screw is a fastener with a slightly rounded, domed pan-shaped head and a built-in drill point, allowing it to drill and tap threads into materials like metal or plastic without pre-drilling. The pan head provides a clean, low-profile finish and a large bearing surface for secure fastening. ... ypically made from materials such as stainless steel, carbon steel, or zinc-coated steel, these screws are strong and corrosion-resistant. They are commonly used in electrical, HVAC, and metalworking applications, where quick installation and reliable performance are essential. The Phillips or Torx drive ensures easy tightening and removal.
