Stainless Steel A2 Solar Hanger Bolt for Metal

Solar mounting fastener standard
Material: A2 (304) stainless steel; tensile strength ≥515MPa, yield strength ≥205MPa
Structure: Integrated hanger ring + full-thread rod + hexagon socket head + anti-loose thread design
Surface Treatments: Passivation (enhances corrosion resistance, salt spray resistance ≥800h)
Size: Nominal diameter M8–M16, rod length 50–200mm, hanger ring inner diameter 15–30mm, load-bearing 50–150kg

Corrosion Resistance: A2 stainless steel resists outdoor rain, UV, and humidity, adapting to long-term outdoor use
Stable Load-bearing: Integrated hanger + full-thread structure avoids breakage, ensuring solar support stability
Easy Matching: Hexagon socket head fits standard tools; thread matches solar metal brackets/rails
Anti-loose Reliability: Special thread design prevents loosening from wind vibration, improving safety
Wide Application: Metal rooftop PV systems, solar bracket suspension, metal structure connection in solar farms
