Improves Product Quality
Ensures correct hole size every time, resulting in better thread engagement and tighter clamp.
How it works
With self-drilling screws, drilling and tapping operations do not occur simultaneously. The drilling operation must be completed and the tip of the drill point must have fully penetrated through the material before thread engagement begins, or stallout will result.
Therefore it is imperative that the flute length be equal to or greater than the total thickness of the material(s) plus air space to be penetrated.
