They are also particularly suitable for fastenings in coastal areas, for boat jetties and swimming pool areas.
The A4 grade screw provides optimum corrosion resistance protection, especially for tropical hardwood with extreme density.
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 A4 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).
