Brass self-drilling screws are specialized fasteners made from brass, a metal alloy primarily consisting of copper and zinc. The self-drilling feature indicates that these screws come with a drill-shaped tip, allowing them to create their own pilot holes as they are driven into materials. This design eliminates the need for pre-drilling, significantly speeding up the installation process. Brass screws are typically used in environments where corrosion resistance and visual appeal are crucial, making them ideal for a variety of applications.
