self drilling countersunk metal screws

The design of these screws features a coarse thread that enables quick and efficient penetration into the chipboard. The sharp point at the tip ensures easy starting, minimizing the chances of splitting. Additionally, the bugle head, with its flat top and slightly larger diameter, allows for flush mounting and a clean finish. The screws are usually made from steel, often with a zinc coating for enhanced corrosion resistance, ensuring a long lifespan even in humid environments.
