Professional Grade Self-Drilling Metal Fasteners
These self-drilling screws are engineered from high-quality galvanized steel for superior corrosion resistance. Each unit features a hexagonal head and an integrated metal washer with a 2mm rubber gasket. This design ensures a secure, vibration-resistant connection when mounting materials to metal frames.
Reliable Fastening for Metal Structures
Installing polycarbonate sheets or terrace roofing onto metal frames often leads to loose connections or water leakage. Standard fasteners may fail to grip properly, compromising the structural integrity of your installation.
Our galvanized screws solve this by combining a sharp self-drilling tip with a protective rubber gasket. This creates a tight, weather-sealed bond that prevents loosening and protects your structure from moisture damage.
