Stainless steel decking screws are mostly used for the fastening of the wooden decking. They might be also an alternative for the fastening of the rear ventilated wooden claddings.
To choose the rigth screw type, we have to know the wood which will be fastened and surroundings where will be the installation. In general, applications are as follows:
Stainless steel C2: softwood in normal conditions/outside (spruce, pine, thermowood, larch...)
Stainless steel A2: exotic/hardwood in normal conditions/outside (ipe, massaranduba, garapa, bangkirai...)
Stainless steel A4: acid and rust enviroment like swimming pools, sea decking...
Used thickness: generally 4,5 and 5,0 mm
Recommended length: cca 2x or 2,5x of the wooden decking/cladding, for exact length see the chart below
|Stainless steel length||Thickness of the wooden decking/cladding|
|5x40 mm||16-18 mm|
|5x50 mm||20-22 mm|
|5x60 mm||24-26 mm|
|5x70 mm||28-30 mm|
|5x80 mm||32-34 mm|
For high quality and long endurance use also distance pads and rubber pads.
Typically, for m2 you will need cca 33 pcs. of the terrace screws (decking width 140 mm, space 8 mm, substructure every 500 mm).
If you prefer the invisible fastening, we can offer you a decking clips.
