Cortex - Aluminum Driller 9.3 m²

The Cortex - Aluminum Driller 9.3 m² pack contains 350 self-drilling screws designed to fasten composite or PVC deck boards to aluminum or steel framing, creating a hidden fastening system by creating a pocket for compatible Cortex plugs (sold separately) to conceal the screw heads. The system is ideal for aluminum framing and provides a clean, screw-free surface once the plugs are installed with a hammer.
