FAQ
What is a flat head screw?
A flat head is countersunk (82 degrees) so it sits flush with the surface. Drill or countersink the hole to match.
Why are self drilling screws made of 410 stainless?
410 stainless can be heat treated hard enough to drill and tap its own hole in steel. It is magnetic and less corrosion resistant than 18-8, so it can show light surface rust in harsh or coastal spots.
