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.

Pan head self-tapping screws are widely used in construction, automotive, electronics, and various DIY projects due to their ease of use and versatility. They are available in different materials, such as stainless steel, zinc-plated steel, or brass, to suit various environmental conditions and strength requirements.
