Self-tapping Screws - Perfect for Metal, Plastic and Wood Work

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.
