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 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
Attractive final appearance – screw head can be coloured to match the façade

Applications

Fastening sheet metal and profiles to steel substructures and framing, with or without intermediate insulation layers
Stainless steel (A4) for fastening in highly corrosive environments
Thin to medium-thick metal-to-metal connections (up to 6 mm)
For applications requiring watertight fastenings with 16 mm washer
Fastening aluminium to aluminium substructures, e.g. for aluminium façade systems
