Features & Applications

Features

  • Self-drilling screw for fast assembly in one step
  • 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 sharp screw tip for chipless fastening and less work for cleaning metal chips
  • Virtually no skidding when starting at an angle or on wet surfaces
  • For reliable fastenings with defined load values

Applications

  • Fastening overlap joints between profile metal sheets and sandwich panels
  • Galvanised carbon steel for fastening in dry, indoor environments
  • Fastening thin metal sheets (up to 2x 1.0 mm)
  • Watertight fastenings – washer included
