Definition of Self-drilling screws: Self-drilling screws are self-tapping screws featuring a drill point used to drill a hole and simultaneously create the mating threads to fasten two pieces of material together. The sharp tip or notch is the unique characteristic that helps identify self-drilling screws that are ideally suited for drilling into wood and metal substructures. The tapered tip acts in the same manner as a drill bit which, along with the natural razor-sharp cutting thread drill, or tap the hole for the fastening process. In the case of self-drilling screws, the regular need for a pre-drilled pilot hole is no longer necessary as self-drilling screws can tap their own holes and give the design of these screws. Unlike self-tapping screws, which cannot drill through metal objects, self-drilling screws can quickly drill through metal materials and do not need a pilot hole to do so. This feature of self-drilling screws gives it an advantage over self-tapping screws and is...
