410 420 Ellow Zinc Needle Point Pan Head Tek Screws With Tapping Thread DIN7981

1. Description:

 

      The ability of a screw to advance when turned, while creating its own thread versus, say, machine screws which require a pre-threaded nut or other female insert. Self-Tapping screws can cut their own threads as the screw is driven in to the material. They function by having a cutting edge which drills away the material, making a tiny hole for the screw to go into. This has nothing to do with the point of the screw but has everything to do with the threads which are designed to cut through the material.
