Features

Reduced drilling point guarantees optimum tightness of the fastening

  • Screws available with a coloured polyester coating (RAL) provide additional corrosion protection and ensure aesthetic matching with roofing or façade cladding. UV stabilisers guarantee long-term colour durability and resistance to fading throughout the service life.
  • Hardened surface of the thread (flexible core). Shape and type of thread designed specifically for use in wood construction.
  • 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 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 special shape of the drill bit designed to ensure fast and trouble-free installation of profiled sheets between each other. The sharp end of the drill prevents movement on the surface of the fastened part.
  • Reduced drill bit (with a diameter smaller than the thread) prevents the holes in thin metal sheets from being recalibrated.
