stainless steel self drilling 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.

Self-drilling screws, as the name implies, eliminate the need for a separate drilling step, as they have a cutting tip designed to pierce through material without requiring a pilot hole. This not only saves time but also reduces the risk of material damage that can occur with traditional drilling methods. The 1 1 4 self-drilling screws refer to a specific size, which typically signifies a 1/4-inch diameter and a 4-thread pitch. The numbers '1' and '20' often represent the diameter in imperial measurements, while '4' indicates the number of threads per inch.
