Screw Fastner Pan Head Self Tapping Screw

A pan head self-tapping screw is a type of fastener characterized by its flat, rounded head with a slightly domed top. The "pan head" design provides a larger bearing surface, which helps distribute the load and prevents the screw from being pulled through the material. These screws are commonly used in applications where a smooth, finished appearance is desired, as the head sits relatively flush with the surface.

The term "self-tapping" refers to the screw's ability to create its own threads as it is driven into the material, eliminating the need for a pre-drilled hole. This feature makes self-tapping screws particularly useful for materials like metal, plastic, or wood, where they can cut or form threads as they are installed.
