A pan head self-drilling screw has a rounded base and a flat head that sits on top of the material it fastens. With its large diameter and high edges, the drive slot is deep, which allows for increased torque while minimizing the risk of damage to the screw. The flat underside also provides greater surface area for a firmer hold.
Pan head self-drilling screws have several unique features that make them ideal for a wide range of applications. Their self-drilling capabilities eliminate the need for pre-drilling, as they have drill-bit points that bite into your substrate.

Self tapping screws are normally used with sheet metal and plastics. This variant has a pan head with a phillips pattern drive. As the name suggests, this type of screw forms its own thread as it is installed into a pre-drilled hole.
