Self-drilling screws for fibre cement board with corrosion-resistant coating and BAZ washers. Perfect for roofing and steel structures.
The Timco 6.3x110mm Self-Drilling Fibre Cement Board Screws provide a secure fastening solution for attaching fibre cement profile sheets to light section steel structures (up to 5mm thickness). These screws are designed for exterior use and feature a corrosion-resistant silver organic coating that withstands over 500 hours of salt spray testing, ensuring long-term durability in harsh weather conditions.
