Self-Drilling Screws, also known as Tek screws, eliminate the need for a pre-drilled hole. The length of the drill point determines the material thickness which the screw can reliably penetrate. When selecting a self-drilling screw design, it is important to consider the material thickness and type of materials to be joined. These stainless teks are great to use in environments that are damp.
Self Drilling screws are a type of screws. They are mainly used to fix color steel tiles in steel structures. They can also be used to fix thin plates in simple buildings. It cannot be used for metal-to-metal bonding. The tail of the drilling screw is in the shape of a drill tail or a pointed tail. No auxiliary processing is required. Drilling, tapping and locking can be directly performed on the installation materials and basic materials, greatly saving construction time. Compared with ordinary screws, its toughness and retention force are high, and it will not loosen for a long time after being assembled. It is easy to use safe drilling and tapping to complete the operation in one go.
Self-Drilling Point: The integrated drill point eliminates the need for pre-drilling or pilot holes, allowing one-step installation into steel, aluminum, and wood materials. Sharp point geometry ensures fast penetration, significantly reduces installation time, and prevents bit slippage for cleaner, more professional results.
EPDM Sealing Washer: Pre-assembled EPDM rubber washer creates a watertight, airtight seal around the screw head, preventing water ingress, condensation, and corrosion at the fixing point. Ideal for metal roofing, cladding, and outdoor applications where long-term weather resistance is essential.
Premium Material Options: Available in hardened carbon steel with yellow, blue, or white zinc plating, black phosphate, or hot-dip galvanized finish for maximum corrosion resistance, as well as stainless steel 410 (hardened), A2 304, and A4 316 marine grade for harsh coastal and chemical environments.
High Tensile Strength: Manufactured from high-grade carbon steel up to Grade 10.9 or hardened stainless steel, delivering superior shear and tensile strength. Precision-rolled threads provide a strong, vibration-resistant grip in thin sheet metal, ensuring secure and durable connections.
Versatile Head Styles: Available in hex washer head, pan head, wafer head, countersunk flat head, truss head, and oval head with Phillips, Torx, or square drive options, matching a wide range of tools and applications while meeting DIN 7504 and ISO 10666 standards.
Wide Application & Custom Service: Suitable for metal roofing, steel frame construction, sandwich panels, purlins, HVAC ductwork, scaffolding, and general sheet metal work. Full size range from M3.5 to M6.3 and 1/4 to 3/4 inch, with OEM/ODM customization, fast sample lead time, and export-grade packaging.
