A screw that can make its own hole when driven into a material, like plastic or metal, is called a self-tapping screw. Self-tapping screws have a cutting edge or sharp point that enables them to cut into the material and generate threads as they are turned, in contrast to regular screws that need a pre-drilled hole. This makes them especially helpful in scenarios where drilling a hole beforehand could be challenging or impracticable.
Self-tapping screws come in a variety of designs, but they usually feature a threaded body, a pointed tip, and occasionally a flute that resembles a drill bit to aid remove material as the screw is driven in. These screws are frequently used in a variety of industries that require a robust and secure fastening, such as construction and automotive applications.
