Self-Tapping Screws

Self-tapping screws drill their own holes when screwed into materials such as wood, plastic and metal. 

The two types of self-tapping screws are thread-forming and thread-cutting.Thread-forming screws are for plastic, deforming the material as the screw enters. Thread-cutting screws are typically used for wood and metal, literally removing some of the material and creating a threaded path for the screw.  

A self-tapping screw is a screw that can tap its own hole as it is driven into hard substrates such as metal or hard plastics. The self-tapping ability is often created by cutting a gap in the continuity of the thread on the screw, generating a flute and cutting edge similar to those on a tap.  For softer substrates such as wood or soft plastics, the self-tapping ability can come simply from a tip that tapers to a gimlet point (in which no flute is needed). Like the tip of a nail or gimlet, such a point forms the hole by displacement of the surrounding material rather than any chip-forming drilling/cutting/evacuating action.
