High-performance cylinder head decking screws designed to deliver a concealed finish on timber and composite decking.
About C2 Deck-Fix Cylinder Head Decking Screws
C2 Deck-Fix Cylinder Head Decking Screws are designed for external decking applications where a discreet, professional finish is required. Featuring a reduced cylindrical head, they sit neatly within the decking surface, making them ideal for installations where visible fixings need to be minimised.
The patented twin-cut tip provides rapid pick-up while helping to reduce timber splitting during installation. An upper thread section assists with clamping, pulling decking boards tight to the joist for a secure and long-lasting fixing.
Finished with a patented multi-layer corrosion resistant coating tested to 1,000 hours salt spray, these screws are suitable for external use and perform well in timber and composite decking applications.
