Overview
The Cobalt 4.8 x 160 screw with hardened tip is the long fixing screw for sandwich panels and insulated trapezoidal roofs: the hardened drill point passes through top sheet and insulation into the lower sheet or purlin, so Cobalt profiles hold on insulated roofs too.

Drive at low speed until the sealing washer just compresses; two per profile or bracket. Matching Cobalt parts: Landscape damwandprofiel (incl. 2 schroeven) and Landscape damwandbeugel (incl 2x smeltschroefen).
For steel roofs Cobalt (Ochten, Netherlands) supplies water-blocking fixings with integrated cable management, so rails and profiles land on purlin or sheet without leaks. Clamps with bonding pins equalise the row with a single earth lead; 20-year factory warranty under the terms on cobalt.solar/downloads.
