Moisture-Proof Measures For Screws

Screws are prone to rust and corrosion in a humid environment, affecting their service life and performance. The following are several common moisture-proof measures for screws:

1. Galvanizing treatment
Galvanizing: A layer of zinc is plated on the surface of the screw to provide moisture-proof and rust-proof protection. Common ones are white zinc plating, blue zinc plating, colored zinc plating, and black zinc plating.
2. Nickel plating and chromium plating
Nickel plating and chromium plating: A layer of nickel or chromium is plated on the surface of the screw to enhance corrosion resistance and moisture resistance while improving the appearance brightness.
3. Dacromet plating
Dacromet plating technology: A new type of anti-corrosion coating using zinc powder, aluminum powder, chromic acid, and other ingredients has excellent moisture-proof and anti-corrosion properties.

4. Stainless steel material
Stainless steel screws: Screws made of stainless steel have natural rust and moisture-proof properties and are suitable for high-humidity environments.
5. Blackening treatment
High-temperature blackening and normal-temperature blackening: The surface of the screw is blackened by high-temperature or normal-temperature treatment to form an oxide film to increase moisture resistance.
6. Anti-rust oil
Apply anti-rust oil: Apply a layer of anti-rust oil on the surface of the screw to form a protective film to prevent moisture from invading.
7. Moisture-proof packaging
Moisture-proof packaging: Use moisture-proof materials to package the screws, such as sealed bags, vacuum packaging, etc., to prevent the screws from getting damp during storage and transportation.
