Flat head self-drilling screws have several key features that make them stand out from other types of screws. Firstly, they have a flat head that allows them to sit flush with the surface of the material being fastened. This makes them ideal for use in applications where a neat and professional finish is required. Secondly, these screws have a sharp point that enables them to drill into the material with ease.
