Self tapping screw

1) Application:

 Steel self tapping screws  is the ability of a screw to advance when turned, while creating its own thread. This ability is sometimes created by a gap in the continuity of the thread on the screw. These edges cut a thread as the screw is driven in to the material. The cutting edge drills away the material, leaving a hole for the screw to go into.
