Ensure a firm and long-lasting fix with these Deck-Tite Composite Plus outdoor screws. Made from stainless steel, they're highly resistant to corrosion - even in marine and coastal areas. These decking screws benefit from a unique TriLock thread form to maximise performance. The first thread drives in without reaming, the second draws the swarf back into the substrate to eliminate jacking, and the third clamps the composite boards tightly in place. They are accredited with TDCA DeckMark+ status for quality and performance. The dark grey head is ideal for matching the colour of your decking.
