12 X 2 1/2 Self-Drilling Screws / Phillips / Flat Head / #3 Point / 410 Stainless Steel
Type BSD: A tapping screw with spaced threads and a drill point which drills its own hole.
Type CSD: A wafer head thread forming screw with machine screw thread pitch and a drill point which drills its own hole.
Both types allow the screw to form mating threads and produce a complete fastening system in a single operation.
Type BSD: The 18-8 stainless drill screw offers superior corrosion resistance while the 410 stainless screw will drill through harder material than the 18-8. The hardness of the material to be drilled should be a minimum of 10-20 Rockwell hardness points.
Minimum torques are the same for stainless and steel self-drill screws. Drill time is 2.5 seconds for a 1mm thick plate.
