Photovoltaic Fasteners

★Zinc Plated Square Trailer U-Bolt
☆Load capacity: Need to match weight of photovoltaic system, wind pressure, snow load and other external forces.
☆Weather resistance: Preferred galvanized or stainless steel material to avoid rust (especially in coastal, high humidity areas).
☆Size matching: U-shaped inner diameter should be slightly larger than diameter of fixed object to ensure tight holding.

★PV Solar Adjustable Roof Hook
☆Adaptability: You need to match the PV module frame thickness and bracket model.
☆Load capacity: PV Solar Adjustable Roof Hook choosing should meet local environmental requirements, such as wind pressure and snow pressure.
☆Environmental adaptability: High anti-corrosion materials should be selected in coastal areas, and low temperature resistant materials in cold areas.
☆Convenience of installation: Preferably hole-free or modular type of PV Solar Adjustable Roof Hook to reduce difficulty of construction.

★Steel Threaded Rod
☆Environmental adaptability: Select the material and thickness according to the climate of the installation site (such as wind pressure grade and snow thickness).
☆Compatibility: Steel Threaded Rod should match the type of photovoltaic module frame (such as frameless, aluminum frame) and bracket system (such as guide rail type, pressure block type).

★Spring Channel Nuts
☆Different structures: Spring channel nut is more complicated than the ordinary nut structure, and a spring groove is arranged on the nut body, and a spring is set to achieve the effect of elastic buffering. The structure of ordinary nuts is relatively simple, usually with a hexagonal or hexagonal structure.
☆Different performance: Spring channel nut provides an elastic cushioning effect that prevents thread loosening caused by vibration and impact loads. Ordinary nuts cannot provide this cushioning effect. Therefore, in the need for loose, cushioning, shock absorption and other aspects of fastener applications, spring nuts are a better choice.
☆Different application scenarios: Due to the different performance, the application of spring nuts and ordinary nuts are also different. The spring nut is usually suitable for occasions where the vibration and impact load is relatively large, such as automobiles, aviation aircraft, high-speed trains, large ships and so on. Ordinary nuts are suitable for more stringent connection requirements and less vibration and shock load.
