HINA2024112802
Colored zinc hexagon bolt (DIN 933) is a full-threaded hexagonal bolt that meets the DIN 933 standard and has been treated with colored zinc on the surface. Colored zinc treatment adds a passivation layer on the galvanized layer to make the bolt surface present a colorful luster (such as gold, blue, green, etc.), which not only provides anti-corrosion protection, but also gives the bolt a beautiful appearance. It is widely used in occasions where corrosion protection is required and appearance is required.
Colored zinc hexagon bolt is a hexagonal head full-thread bolt produced in accordance with the DIN 933 standard. After electrogalvanizing, a colored protective film is formed through a passivation process. Its main function is to provide anti-corrosion protection, while the appearance is bright, suitable for places with high aesthetic requirements.
Colored zinc hexagon bolts are widely used in:
Construction industry: steel structures, bridges, fences, etc.
Mechanical equipment: equipment that requires anti-corrosion and has high appearance requirements.
Automobile manufacturing: connection of automotive parts.
Home appliances and furniture: beautiful and anti-corrosion fastening connections.
Advantages
Good corrosion resistance: The colored zinc coating provides moderate corrosion resistance and is suitable for outdoor and lightly corrosive environments.
Beautiful appearance: The colored glossy surface is suitable for occasions that require beauty.
Economical: Compared with hot-dip galvanized or stainless steel bolts, it has a lower cost and is suitable for large-scale applications.

1.What is color zinc treatment?
Color zinc treatment is an electroplating process that adds a passivation film to the galvanized layer to form a colorful protective zinc layer on the surface of the bolt. The specific process includes:
a. Electrogalvanizing: A layer of zinc (usually 5-20 microns thick) is plated on the surface of the bolt by electrolysis.
b. Passivation treatment: The galvanized layer is chemically passivated (mainly using chromate) to form a colorful oxide film.
c. Sealing treatment (optional): Further enhance the anti-corrosion performance.
2.What are the precautions for selecting and installing hexagonal bolts?
Environmental adaptability: Suitable for neutral or indoor environments, not recommended for long-term exposure to moisture or salt spray environments.
Prevent thread damage: Color zinc threads are thinner, avoid excessive torque during installation to cause coating damage or thread stripping.
"Matching nut selection" requires nuts with the same surface treatment to ensure anti-corrosion performance and smooth thread engagement.
Lubrication measures: To avoid coating damage during installation, anti-seizing lubricant can be applied to the threaded part.
3.What materials are blackened hexagonal bolts generally made of?
Common materials are carbon steel and alloy steel. For example, 8.8-grade blackened hexagonal bolts are generally made of 8.8-grade carbon steel; 12.9-grade high-strength blackened external hexagonal bolts are mostly made of SCM435 alloy steel or 35Crmo and other materials
