Diameter, length and thread are chosen by what the screw goes into. The protection is chosen by where it sits.
Timber
For a timber supporting frame, with a coarse thread that grips soft fibre and holds even as the timber moves.
- Diameter
- Ø 6.3 mm
- Lengths
- 100 – 310 mm
- Head
- hexagonal HEX
- Thread
- coarse
- Coating
- zinc 12 μm + paint 50 μm
Concrete
The same screw profile works in concrete too — a self-drilling point and a coarse thread, with no plugs and no extra tools.

Dacrotized 500H
A ceramic coating that stands a 500-hour salt spray test. That is how long the accelerated ageing in a salt fog chamber lasts — the measure by which coatings for outdoor use are compared.
12 + 50μm
Screws for a timber supporting frame
Zinc and paint
A zinc coating of 12 μm and a paint coating of 50 μm. The thickness of the layer is what decides matters for a screw that spends its whole life outdoors, exposed to damp and sun.

Range
Screws from our range
Self-drilling screws are the best solution for fixing sandwich panels quickly, securely and lastingly to steel or timber substructures. Thanks to the integrated drill point, drilling and driving happen at the same time, with no need to pre-drill the holes. That speeds up installation considerably and reduces the need for additional tools.
| Type of screw | Diameter (mm) | Lengths (mm) | Material | Head | Thread |
