Fastener surface treatment is the process of forming a covering layer on the surface of a workpiece using a specific method, with the goal of endowing the product's surface with beautiful anti-corrosion effects.
Surface treatment is the process of forming a covering layer on the workpiece's surface using a specific method. The goal is to give the product a beautiful surface and an anti-corrosion effect. The following methods are responsible for all surface treatment methods:

1. Electroplating: Immerse the parts to be electroplated in an aqueous solution containing the metal compound to be deposited, then pass a current through the plating solution to precipitate and deposit the electroplated metal on the parts. In general, electroplating includes galvanized, copper, nickel, chromium, copper-nickel alloy, and other metals, as well as boiled black (blue), phosphating, and other processes.
2. Hot-dip galvanizing: This is completed by immersing carbon steel parts in a molten zinc plating tank at 510 °C. As a result, the iron-zinc alloy on the surface of the steel gradually transforms into passive zinc on the product's outer surface. A similar process is hot-dip aluminum plating.
3. Mechanical plating: Impact the product's surface with plated metal particles and cold weld the coating to the product's surface.

Generally, screws are electroplated, but hexagonal wood screws used in electric power, highways, and other outdoor applications are hot-dip galvanized; the cost of electroplating is generally 0.6-0.8/kg, while the cost of hot-dip galvanization is generally 1.5-2/kg, so the cost is higher.
