Features & Applications
Features

- 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
- Creates more 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)
