What Is a Phillips Flat Head Self Tapping Screw?

Phillips Flat Head Self-Tapping Screws are a type of fastener designed with:

A flat (countersunk) head that sits flush with the material surface when fully driven.
A Phillips drive recess (cross-shaped) for easy installation using a Phillips screwdriver or power tool.
A sharp, self-tapping thread that cuts its own mating threads in materials like metal, plastic, or wood without requiring a pre-drilled hole (though pilot holes may be needed for harder materials).
These screws are widely used in applications where a smooth, flush finish is desired while providing strong holding power.
