The self-tapping feature of these screws allows them to cut their own thread into the metal substrate, making installation quick and efficient. The sharp cutting edges of the screw create threads as it's driven in, ensuring a secure hold without damaging the surrounding material. This characteristic is especially useful when working with thinner metals, which may be prone to deformation under excessive force.

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.
