Self Drilling Screws

Our Self Drilling Screws are designed to drill, tap and fasten into metal in a single operation, helping to reduce installation time and eliminate the need for a separate pilot hole in many applications. Commonly known as Tek screws, these fasteners feature a hardened drill point that cuts through sheet metal and creates a secure thread as the screw is installed.

Available in a range of diameters, lengths, materials and finishes, our self drilling metal screws are suitable for use across construction, fabrication, roofing, cladding, HVAC installation and general engineering. The range includes Hexagon Washer Head Self Drilling Screws, Pan Head Self Drilling Screws and Countersunk Self Drilling Screws, allowing the most suitable head style to be selected for the required fixing method and finished appearance.

Hexagon Washer Head Self Drilling Screws

Hexagon Washer Head Self Drilling Screws provide a large bearing surface that helps distribute pressure across the material being fixed. The external hexagonal head allows the screw to be installed using a socket, spanner or compatible power tool, making this style ideal for efficient installation in metal roofing, cladding, steel framing and sheet metal fabrication. The integrated washer-style flange also helps provide a secure and stable fixing.

Pan Head Self Drilling Screws

Pan Head Self Drilling Screws feature a low-profile rounded head with a flat underside that sits securely against the surface of the material. They are commonly used for joining sheet metal, brackets, electrical components, ducting and light engineering assemblies. The head design provides a neat finish while retaining a suitable bearing area around the fixing point.

Countersunk Self Drilling Screws

Countersunk Self Drilling Screws are designed to sit flush with or below the surface of the installed material. Their tapered head fits into a countersunk opening, creating a smooth finish that reduces protrusion and helps prevent interference with surrounding components. These screws are well suited to metalwork, panels, enclosures, signage, fabrication and applications where a clean finished surface is required.
