Product Description
Product Overview
This product is a hexagon socket screw specifically designed for photovoltaic (PV) applications, complying with GB/T70.6 standard. It is manufactured from Q235 carbon steel with a performance grade of 4.8, and the surface is treated with hot-dip galvanizing for high corrosion resistance. Optimized specifically for the installation needs of PV bracket systems, the product is usually combined with flat washers and spring washers or adopts a special locking structure. It can provide a firm and reliable connection in harsh outdoor environments (sunlight, rain, temperature difference) and has excellent corrosion resistance.
Core Advantages
-
Excellent Weather Resistance and Corrosion Protection: The hot-dip galvanized layer is thick and fully covered, providing long-term corrosion protection far superior to ordinary electroplating, adapting to harsh outdoor environments.
-
PV-Specific Design: Optimized for the connection characteristics of PV brackets (such as clamp and guide rail installation), ensuring convenient installation and reliable connection.
-
Multiple Precision Grades Optional: Grade C/B/A precision is available to meet different assembly requirements from basic brackets to precision adjustment parts.
-
Good Mechanical Performance: Grade 4.8 strength meets the force requirements of the PV bracket structure, ensuring the stability of the connection.
Applicable Industries
-
Photovoltaic Power Generation Systems: Key connection points such as clamp fixation of solar PV panels and brackets (aluminum alloy or steel), guide rail connection, and column assembly.
-
Outdoor Energy Facilities: Installation and fixation of solar street light brackets and small wind-solar hybrid power station brackets.
-
Agricultural PV Greenhouses: Connection of metal structures and installation of components in agricultural PV greenhouses.
-
Transportation and Municipal Facilities: Structural installation of integrated projects such as PV carports and PV bus shelters.
-
Building-Integrated Photovoltaics (BIPV): Metal connectors for some building-attached PV structures (subject to specific building design).
Warm Tips
-
Please use qualified hexagon socket tools during installation and apply the specified torque to avoid thread slipping or insufficient fastening.
-
During the installation of hot-dip galvanized products, try to avoid scratching the galvanized layer to maintain the best corrosion resistance.
-
In highly corrosive areas such as coastal and industrial pollution areas, it is recommended to consult whether higher-level corrosion protection treatment (such as zinc-aluminum coating) or regular maintenance plans are needed.
