Typically made from stainless steel, self-drilling screws are characterised by their drill-shaped point. This point enables the screws to drill into materials without the need for pre-drilled pilot holes, resulting in a more efficient fastening process.
 
Self-drilling screws are useful for fastening wood and metal. They can attach wood to wood, metal to metal and metal to wood, and they're ideal for most lightweight and low-density materials. It's also easy to know how to use a self-drilling screw due to their simple design.
