Self-tapping screws, mainly made of carbon steel or stainless steel, are widely used on plastics, metal and
wood materials. 
The best part in the use of self-tapping screws is that there is no need to drill holes before they are used. 
The two basic types of self -tapping screws are thread-forming screws and thread-cutting screws. The
thread-forming screws are commonly used for plastic, deforming the material as the screws enter. The 
thread-cutting screws are typically used for wood and metal, removing some of the material and creating 
a threaded path for the screw.
