Self Drilling Screw/Tapping Screw

A self-tapping screw is a screw that can tap its own hole as it is driven into the material. More narrowly, self-tapping is used only to describe a specific type of thread-cutting screw intended to produce a thread in sheet materials. When a screw is specifically stated to be self tapping, it is usually used for metal since the material is difficult to allow the screw to simply turn in. These screws reduce the installation time and are drilled using screw guns.
