FORTRESS FASTENERS

Purpose-built for hardwood decking, Fortress Fasteners deliver strength, speed and a clean, refined finish.

Engineered for demanding exterior environments, these screws offer exceptional corrosion resistance, making them a reliable choice for Tough Decks’ premium hardwood timber. The precision drill point is designed to cut cleanly through dense hardwood, reducing the risk of splitting while ensuring a smooth installation process.

Fortress Fasteners feature a self-drilling design for faster fixing and consistent results. The discreet head profile allows the screw to sit neatly within the board for a tidy surface finish, while the specialised thread and shank configuration provide superior holding power and long-term stability.

Strong, dependable and built for performance — Fortress Fasteners are made to match the quality of your hardwood deck.

Disclaimer

Tough Decks claims no responsibility for the corrosion or discolouration of any hardwood timber or screws due to environmental factors.

These factors are not limited to but include pool water, air pollution, salt exposure, or any other high corrosive factors
Tough decks only recommend 316 stainless steel fixings. This can reduce the incidence of corrosion or staining but in rare cases corrosion can still occur.
