What are the characteristics of hot galvanized screws?

What are the characteristics of hot-dip galvanized screws? Screws are tools that use the physical and mathematical principles of the bevel rotation and friction of the object to gradually tighten the objects and parts. Screws are a generic term for fasteners, spoken daily.
1. Hot-dip galvanized screws are obtained by dipping and pickling the pickled screws into zinc solution, and attaching a layer of zinc to the surface of the screws to obtain hot-dip galvanized screws.
2. The performance of hot-dip galvanizing is anti-corrosion, and the performance of screws is tightening. Coating is a surface treatment process with better corrosion resistance than hot-dip galvanizing.
3.Using electrolytic equipment, the pipe fittings are degreased, pickled, and then put into a solution containing a zinc salt, and connected to a negative electrode.
