What Is Fastener Coating And Plating?

Fastener coating and plating are surface treatments applied to fasteners, such as screws, bolts, nuts, and other types of hardware, to enhance their performance, durability, and resistance to corrosion. These processes help protect the fasteners from environmental factors and improve their appearance. Here are some common types of fastener coatings and platings:

Zinc Plating: Zinc is commonly used as a coating because it provides corrosion resistance to the underlying metal. Zinc-plated fasteners are often used in indoor applications or in environments with minimal exposure to harsh conditions.

Galvanizing: Galvanizing involves coating fasteners with a layer of zinc by either hot-dip galvanizing or electroplating. Hot-dip galvanizing involves immersing the fasteners in molten zinc, while electroplating involves applying a zinc coating through an electrolytic process. Galvanized fasteners are known for their excellent corrosion resistance, making them suitable for outdoor and marine applications.

Nickel Plating: Nickel plating is used to provide a decorative and corrosion-resistant finish to fasteners. It offers good durability and a bright, attractive appearance. Nickel plating can also provide some level of abrasion resistance.

Chrome Plating: Chrome plating is a process where a layer of chromium is applied to the fastener’s surface. Chrome-plated fasteners have a shiny, reflective finish and offer corrosion resistance. They are often used in applications where appearance is important, such as in the automotive industry.

Phosphate Coating: Phosphate coatings, such as zinc phosphate or manganese phosphate, are often applied to fasteners for corrosion resistance and improved lubricity. These coatings can provide a base layer for additional finishes or coatings.

Black Oxide Coating: Black oxide is a conversion coating that forms a thin layer of black iron oxide on the fastener’s surface. It provides mild corrosion resistance and an attractive black finish. Black oxide is commonly used in applications where a decorative appearance is desired.

Dacromet Coating: Dacromet is a type of coating that provides corrosion resistance and protection against harsh environmental conditions. It is often used in automotive and industrial applications.

Choosing the appropriate coating or plating for fasteners depends on factors such as the application, environmental conditions, and desired performance characteristics. Each type of coating or plating has its advantages and limitations, and selecting the right one is crucial to ensure the longevity and effectiveness of the fasteners in a given application.
