This high-strength PV bolt stands out for its superior load-bearing capacity and durability for large-scale photovoltaic projects. Its 42CrMo alloy steel material provides a tensile strength of 1040 MPa, meeting the fastening requirements of large-span photovoltaic bracket systems. The dacromet coating offers 1000+ hours of salt spray corrosion resistance, suitable for regions with high humidity or occasional salt spray exposure. The torx drive design reduces tool slippage during installation, improving tightening accuracy and reducing construction errors. It is specifically optimized for high-wind load scenarios, providing reliable structural support for large photovoltaic power stations.
