Self tapping screws cut their own path into material. They have sharp cutting ridges that allow them to slice into the material without pre-drilling a hole. Pozidrive pan head self tappers have a raised head which has a flat, level underside to it. Round head fixings were actually designed for fixing against metal surfaces, but they are now commonly used to fix to a variety of rigid surfaces. They are the most commonly used head type in applications where a flush finish is not a necessity.
