China round head machine screws

Machine screws during transportation, zinc coating, often appear white, black, black and other phenomena, mainly caused by galvanized layer and corrosive media and atmospheric moisture, oxygen, carbon dioxide exposure.

China round head machine screws

In order to prevent this phenomenon, the surface state of the good material that can be tried is before the screw processing. Due to the galvanizing process, the surface of the defective screw is easily permeated by corrosive medium such as acid, alkali, salt, etc., and it is difficult to clean and cause corrosion.


Reasonable choice of packaging materials, avoiding the use of plastic products not with zinc, packaging materials, such as galvanized iron sheet metal is the best, in the box can be placed in the humidity of the amount of desiccant to reduce the relative humidity compatible to reduce and prevent harmful gases The erosion of the warehouse.



We also accept customization order according to your samples and drawings. If you have other questions or concerns, please feel free to contact us.
