  • Spanner (snake eye) drive style is uncommon creating a more secure fastener assembly
  • A machine screw is commonly identified by its small size
  • Commonly used in bathroom stalls or on public art displays
  • Rust and corrosion resistant
  • Suitable for external environments where fresh water is present
  • Scratching or burring the metal will not create surface rust as the metal itself is corrosion resistant not just a coating

1/4-20 Spanner flat head security machine screws are made of 18-8 stainless steel.
