surface treatment for custom fasteners

Surface treatment for custom fasteners in China is an important part of the manufacturing process. The surface finish of a fastener provides protection against corrosion, wear and tear, and also impacts the overall aesthetic appearance.

Commonly used methods include zinc plating, blackening, hot dip galvanizing, or plating.

the surface treatment we can do

hot galvanizing

Hot galvanizing is a surface treatment for fasteners that is used to protect against corrosion and rust.

It involves submerging the fastener in molten zinc, which forms a protective coating on the surface. This process also increases the strength of the material and improves its durability. The hot galvanizing process can be used on almost any type of metal or alloy as well as on some plastic parts. It is an effective way to ensure long-term protection against corrosion, rust, and wear and tear. The cost of hot galvanizing depends largely on the size and shape of the fastener being treated but is typically relatively inexpensive compared to other surface treatments.

Hot galvanizing is considered one of the most reliable methods for protecting fasteners from corrosion, enabling them to withstand harsh environments and last much longer than those without a protective coating.


Electrogalvanizing is a surface treatment for fasteners that is often used in construction and industrial applications.

It involves the application of zinc to metal surfaces using an electric current, creating a layer of protection against rust and corrosion. This type of surface treatment is especially useful when fasteners are exposed to damp and humid environments, as it provides excellent protection against the elements. Additionally, electrogalvanized fasteners are highly resistant to chemical damage and wear, making them well-suited for use in harsh conditions. The process also results in a smooth finish with a bright, attractive appearance that does not require painting or other additional treatments.

Electrogalvanizing offers many benefits over traditional galvanization methods, including increased durability, cost savings, and reduced environmental impact.


PTFE surface treatment for fasteners is a great way to improve the durability and performance of any fastener.

This type of treatment creates a thin layer of PTFE that helps prevent corrosion, improve lubricity, and reduce friction. It also helps reduce the risk of galling, seizing, and thread stripping. This makes it an ideal choice for use in extreme temperatures, high humidity or wet environments, or areas where frequent vibration is present. The PTFE surface treatment can also increase the life expectancy of your fasteners by up to five times over untreated fasteners.

Additionally, it can help protect your fasteners from seizure due to dirt or other contaminates, making them easier to install and remove when needed.


Dacromet surface treatment for fasteners is a great solution for improved corrosion resistance and wear resistance.

This system consists of applying a zinc-rich base coat, followed by an organic top coat. The organic top coat provides superior adhesion and corrosion protection, while the zinc-rich base coat ensures maximum galvanic protection against rust and oxidation. The Dacromet process also results in a smooth, uniform finish that can significantly extend the life of fasteners.

Additionally, this surface treatment is cost-effective and easy to apply, eliminating costly delays associated with traditional rust protection methods.


Blackening Surface Treatment is a process used to protect metal fasteners such as bolts, nuts, and screws from corrosion.

This treatment usually involves the application of a black oxide compound to the surface of the fastener. The black oxide acts as a barrier that prevents rust and other forms of corrosion from forming on the metal. Blackening treatments offer superior protection against environmental factors such as moisture, salt, and chemicals. Additionally, blackening treatments can improve the appearance of the fastener by providing it with a uniform black color.

This treatment is relatively inexpensive compared to other surface coatings like galvanizing or plating, making it an attractive option for many applications.

Sliver and nickel planting on the surface

Silver and nickel plating on the surface of fasteners is a popular surface treatment used for industrial applications.

This type of plating provides superior corrosion resistance and lubricity, as well as improved wear resistance. Silver and nickel plating also improve the appearance of the fastener, making it more aesthetically pleasing. As with other types of metal plating, silver and nickel plating can be applied to all types of fasteners, including bolts, nuts, screws, and washers. The process involves electrolytic deposition, which deposits a thin layer of silver or nickel onto the surface of the fastener. This thin layer protects against wear, moisture, abrasion, and oxidation. Silver and nickel are also highly conductive materials making them ideal for use in electrical applications such as circuit boards and automotive components.

In addition to providing superior corrosion protection, silver and nickel plating also enhances the aesthetic appearance of the fastener.
