Features

Stainless steel self drilling screw with reduced drilling point guarantees optimum tightness of the fastening

  • The stainless steel self-drilling screw manufactured in BIMETAL technology combines high mechanical strength with excellent corrosion resistance.
  • The case-hardened thread ensures high cutting performance and secure anchorage in the substrate, while maintaining a ductile core. This increases resistance to dynamic loads and reduces the risk of screw fracture.
  • The reduced drill point enables fast drilling start and precise screw guidance, minimizing the risk of slipping on the sheet surface and damage to the protective coating.
  • The thread extended up to the head prevents screw overdriving and ensures strong clamping of the connected elements. It allows installation without a sealing washer in applications where watertightness is not required.
  • The specially designed thread geometry and pitch enable stable and durable fastening of profiled sheets to each other, ensuring high load-bearing capacity of the joint.
  • The self-vulcanizing EPDM sealing washer is resistant to UV radiation, ageing, and temperature fluctuations. It guarantees long-term watertightness and protects the joint against water ingress.
  • The screw is intended for outdoor applications and maintains its performance in environments with elevated humidity and significant temperature variations.
