Features

Special design of the sharp point guaranteeing quick and firm installation in wood substrate

  • 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 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 in wood. The sharp end of the drill prevents the drill bit from moving across the surface of the workpiece to be fastened.
  • Reduced drilling point ensures optimal tightness and correct hole diameter in the wood.
