A self-tapping screw is a type of fastener designed to create its own hole as it is driven into materials like wood or metal. Unlike regular screws, which require a pre-drilled hole, self-tapping screws have a sharp tip and threads that allow them to cut into the material, making installation quicker and easier. These screws are commonly used in construction and manufacturing due to their efficiency. They come in various sizes and materials, including stainless steel and zinc-plated options, to suit different applications and environments. Their ability to secure components without additional tools makes them a popular choice among builders and DIY enthusiasts.
