RAL self-tapping screws

RAL self-tapping screws are fasteners painted in various colors according to the German standard of the same name.

The standard was developed almost 100 years ago and is continuously updated.

These self-tapping screws are most often used for roofing work. They are threaded rods with a hexagon head at one end, with a sealing washer and a rubber gasket beneath it. This design makes the connection tighter and protects it from dust and moisture ingress. The tip of these screws is not sharp but drill-shaped.

How to use

Before installation, the right self-tapping screws must be selected: some are designed for driving into metal, others into wood, and they differ in thread pitch. Installation itself is simple: thanks to the drill-point tip, there is no need to drill holes separately. A drill or screwdriver with a special bit is enough.

At FLOK you will find RAL self-tapping screws in all colors. All that remains is to choose the ones that suit your roof.
