Features & Applications

Features

  • Self-drilling screw for fast assembly in one step
  • New drill tip for fast drilling and low failure rate, even in hard steel
  • EPDM rubber washer – creates a more reliable seal against water
  • Fast and robust drill tip with Racing Tip technology – a wave-form cutting edge which removes chips much faster and helps prevents point burn-out
  • Especially suitable for highly stressed connections, such as roofing sheets or decking sheets where not exposed to the weather

Applications

  • Fastening sheet metal and profiles to steel substructures and framing, with or without intermediate insulation layers
  • Galvanized carbon steel for fastening in dry, indoor environments
  • Thin to medium-thick metal-to-metal connections (up to 6 mm)
  • Especially suitable for cassette system walls on HTU cast-in channels, C/U profiles etc.
