C2 Deck-Fix Cylinder Head Decking Screws
Premium cylinder head decking screws designed to deliver a concealed, professional finish with strong board-to-joist clamping in timber and composite decking.
About C2 Deck-Fix Cylinder Head Decking Screws
C2 Deck-Fix Cylinder Head Screws are engineered for clean, secure decking installations where both appearance and performance matter. The slim cylindrical head sits neatly within the board surface, keeping the finish tidy while maintaining serious holding strength.
Unlike standard countersunk decking screws, the cylinder head is designed to reduce visible fixings without compromising clamping performance. The upper thread pulls decking boards tight to the joist, helping prevent movement over time.
This range includes both exterior coated and stainless steel options, allowing you to choose the correct level of corrosion resistance for your environment.
