Carbon Steel Galvanized Zinc Self-Drilling Screw 

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.
