Self-drilling screws are a type of screw used in a variety of fastening and fixing applications. 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.

Available in a range of sizes, lengths, and thicknesses, self-drilling screws are handy and versatile. They are sometimes also known as Tek screws. Tek was originally a brand name for a popular manufacturer of these screws, but over time, the name Tek screw has since become synonymous with this type of fastener.

Self-drilling screws can cut through a variety of materials including wood and metal such as softer steel. As a result of this, self-drilling screws are also ideal for more heavy-duty applications and industries, especially when compared to alternatives like self-tapping screws.
