Countersunk head self-drilling screws are versatile fasteners commonly used in construction and assembly. Their design combines a Phillips drive for easy installation with a flat head that sits flush with the material surface. These screws are self-tapping, meaning they create their own threads as they penetrate the material. The core hole formed by the screw ensures a secure hold, making them ideal for attaching metal or wood to substructures.
