Roofing Screw RAL

Roofing screw RAL is a rod with external thread featuring a high profile and a self-drilling tip.

Material: carbon steel with anti-corrosion zinc plating.

The hex head of the screw is coated with durable polymer paint matching the RAL color catalogue. The product comes with a washer with a rubber seal for waterproofing and to compensate for thermal deformation of the roof.

Application and installation

The fasteners are used for joining metal tile or profiled sheets to each other, as well as for mounting them onto metal or wooden frames. A screwdriver with a hex bit attachment or a socket wrench is used for installing the screws. When joining metal parts, pre-drilling a hole may be required, depending on the base thickness and the power of the screwdriver. In wood, the fastener is screwed in without pre-drilling.

FLOK supplies roofing screws together with special washers. Fasteners for wood and metal differ in drill tip shape and dimensions. For help selecting fasteners, FLOK specialists provide free technical consultation.
