Features & Applications

Features

  • Self-drilling screw for fast assembly in one step
  • Perfectly sealed fastening points
  • Perfect Sealing (PS) feature – specially engineered geometry below the head which prevents over-compression of the EPDM washer, helping to reliably seal out 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
  • For reliable fastenings with defined load values

Applications

  • Fastening sheet metal and profiles to steel substructures and framing, with or without intermediate insulation layers
  • Galvanised carbon steel for fastening in dry, indoor environments
  • Thick metal-to-metal connections (up to 15 mm)
  • For applications requiring watertight fastenings with 16 mm washer
