High Performance Stainless Steel Fastening Solution
These self-drilling screws are engineered for efficient metal construction and facade projects. Each 5.5 x 70 mm unit is crafted from durable A2 stainless steel to provide superior corrosion resistance. The integrated hex flange head and sealing washer ensure a secure, weather-resistant connection for professional installations.
Reliable Fastening for Metal and Solar
Traditional fastening methods often require time-consuming pre-drilling, which can lead to alignment errors and structural fatigue. These screws eliminate the need for pilot holes, significantly reducing installation time while maintaining a tight, secure grip on metal surfaces.
Designed for harsh environments, the A2 stainless steel composition prevents rust and degradation. The included sealing washer provides an essential barrier against moisture, protecting your structural integrity in solar mounting and exterior cladding applications.
