Due to their high level of resistance to weather conditions, A2 stainless steel decking screws are used for fastening outdoor terraces and floor coverings. They create a perfect connection and are especially suitable for medium and hard woods.
The user is responsible for design considerations.

The appropriate substructure must be selected depending on the decking panels/boards to be installed.
Recommended laying distance of the substructure 50-60 cm = approx. 35 screws per m²
Each support point of the planks on the substructure must be fixed with two screws
The recommended gap between the joints of the planks is 4-7 mm, depending on the type of wood
Important application instruction:
Pre-drilling of the wood may be necessary depending on the density and moisture level of the wood. It is recommended to screw in the A2 stainless steel decking screw at a low speed. Preliminary tests are generally required. In order to obtain a perfect processing result, the wood to be laid should have a moisture content of 16% +/- 2%.
For an absolutely perfect appearance, it is recommended to countersink the drill holes using our drill bit with push-on countersink (art. no. 181 900 009 75 or 181 900 000 75).
