Photovoltaic bolts are high-strength fastening components specifically engineered for solar mounting systems. Manufactured from premium-grade carbon steel and stainless steel materials, these bolts are designed to deliver exceptional corrosion resistance, reliable clamping force, and long-term structural stability in demanding outdoor PV environments.

Our photovoltaic bolts feature hot-dip galvanized or dacromet coating with a thickness of 60-85μm, ensuring superior protection against UV radiation, moisture, salt spray, and extreme temperature fluctuations. The precision-rolled threads provide consistent engagement and optimal torque retention, minimizing the risk of loosening under wind loads and vibration.

Available in a comprehensive range of diameters from M6 to M24 and lengths from 20mm to 300mm, our photovoltaic bolts are compatible with all major mounting system configurations including single-axis trackers, fixed-tilt ground mounts, and rooftop ballasted systems. Each bolt undergoes strict quality inspection including dimensional verification, tensile testing, and salt spray testing to guarantee compliance with international standards such as ISO 898-1, DIN 933, and ASTM A325.

With a proven track record of deployment in over 100 MW of PV installations globally, Handan Jiaxiong’s photovoltaic bolts offer the perfect combination of durability, reliability, and cost-effectiveness for utility-scale solar farms, commercial rooftop systems, and distributed generation projects.
