What kind of bolts and nuts are recommended in solar plants?

DIN912 hex bolt and nut: DIN912 refers to a German industrial standard, which is widely used internationally, especially in solar power stations. This kind of bolt has a socket head cap, which allows tools like screwdrivers to be inserted better, facilitating tightening and removal and is less likely to cause damage to the bolt head.

The hex bolt and nut have a very wide range of applications. In particular, specifications like M6×10, M10×50, M10×60, M12×60, and M12×80 are used in almost every project of solar brackets

To meet the requirements of different solar power stations,  carbon steel, stainless steel, and aluminum alloy are usually available. Different materials have different characteristics and application scenarios. For example, carbon steel has relatively high strength and low cost; stainless steel has good corrosion resistance and is suitable for environments with high requirements for rust prevention; aluminum alloy is lighter in weight and is often used in occasions where weight is a concern.

Surface treatments include galvanizing, nickel plating, and blackening. Galvanizing can enhance the rust prevention ability of screws and prolong their life; nickel plating can not only provide certain anti-rust performance but also make the appearance of screws more beautiful; blackening is mainly to improve the hardness and wear resistance of the screw surface.
