TORX Stainless Steel Screws for Decking and Cladding – Outdoor Use
Screws made of stainless steel (INOX) for decking and cladding have been developed for outdoor applications where corrosion resistance, durability, and a clean finish are essential. They are especially suitable for humid environments, coastal areas, and regions with high salinity.
Unlike galvanized or indoor screws, stainless steel screws maintain their mechanical performance and appearance over time, even in demanding environmental conditions.
Why choose INOX screws for decking and cladding
Corrosion-resistant stainless steel
Ideal for outdoor use, humidity, sea spray, and saline environments.
Torx drive
Allows for a high torque with a lower risk of stripping the head.
High durability
They maintain resistance and finish over the years.
Clean penetration in wood
Optimized thread for smooth and controlled screwing.
Secure and stable fastening
Maintains the clamping pressure in outdoor applications.
Typical applications
Recommended for:
Natural or treated wood decks
Wood exterior cladding
Wooden facades
Pergolas and outdoor structures
Walkways, platforms and swimming pool areas
Whenever the fastening is exposed to the outdoors, especially in coastal areas, the use of stainless steel screws is highly recommended.
Who they are for
Recommended for:
Deck and facade installers
Carpenters
Construction companies
Outdoor DIY Projects
Not recommended for:
Dry interior applications
Heavy structural connections (use structural construction bolts)
Advantages over galvanized screws
Much greater resistance to rust
Excellent behavior in a maritime environment
Longer lifespan abroad
Better appearance over time
Less maintenance required
Galvanized screws can corrode quickly in coastal areas.
Our supply philosophy
We select only stainless steel screws suitable for outdoor use, with consistent quality and proven performance, to ensure professional results in every project.
Simple Objective:
Durable outdoor fixtures, even by the sea.
How to choose the right size
Length: It must completely penetrate the deck board or cladding strip and sufficiently penetrate the substructure.
Diameter: It must be suitable for the type of wood and the expected load.
Pre-furo: Recommended for hardwoods and tropical woods.
If you have any questions, we can recommend the correct measurement.
Material comparison
AISI 410
Stronger and harder than A2/A4
Lower resistance to corrosion
It can develop rust in humid environments or coastal areas
INOX A2 (AISI 304)
Good corrosion resistance
Suitable for general outdoor use
Suitable for normal humid environments
Excellent cost-benefit ratio
INOX A4 (AISI 316)
Superior corrosion resistance
Recommended for coastal areas and marine environment
Greater resistance to salinity, chlorides, and pollution
Ideal for pools, marine facades, and highly exposed areas
