Self-drilling Screws

Featured products

Self-drilling screws, often referred to as Tek screws, are high-performance fasteners characterized by an integrated drill-shaped point. Manufactured from high-strength carbon steel or stainless steel, these screws are typically finished with premium zinc plating or organic coatings to ensure maximum durability. The unique drill point allows the screw to function as both a drill bit and a fastener, enabling it to pierce and thread into metal or wood in a single, seamless operation.

Compared to traditional screws, self-drilling versions significantly enhance installation efficiency by eliminating the need for pre-drilling pilot holes. This makes them highly cost-effective for large-scale assembly. They are predominantly utilized in metal-to-metal bonding, roofing systems, steel structure fabrication, and HVAC installations.

Key Features:

  • Integrated drill-shaped point for one-step installation
  • Eliminates the need for separate pre-drilling and pilot holes
  • High-strength carbon steel core with heat treatment for rapid penetration
  • Superior shear and tensile strength for heavy-duty metal bonding
  • Available with weather-resistant coatings (C3/C4) for outdoor durability
