Black Stainless Steel Rivets
Weight Range ： 0.5g–500kg
Dimensional tolerance ： ±0.1mm
Black stainless steel rivets meet international A2-70 and A4-70 strength standards. Its tensile strength exceeds 700 MPa. Take a 4 mm diameter rivet as an example. It can withstand a continuous pulling force of about 1.3 tons. This strength ensures that it can withstand strong vibrations. Can also withstand impact loads. The product has a high quality black oxidation finish. Passes standard salt spray test for more than 72 hours. It is particularly suitable for heavy machinery manufacturing. Also suitable for outdoor building structures. These areas require high connection strength. At the same time, the requirements for service life are very strict.
The installation is very efficient. Skilled workers use specialized tools. It only takes 3 seconds to install a single rivet. This greatly improves assembly efficiency. The product adapts to a wide temperature range. It can remain stable from minus 40 degrees Celsius to 300 degrees Celsius. Its electrochemical compatibility is very good. It can reduce the risk of galvanic corrosion by more than 50% when connecting dissimilar metals. Products comply with environmental standards. The content of hazardous substances is always below the 0.1% limit.

Advantages
Sturdy and durable structure
This rivet meets A2-70 or A4-70 strength standards. Its tensile strength exceeds 700 MPa. A 4 mm rivet can withstand about 1.3 tons of pulling force. It effectively resists vibration and shock.
This ensures that the connection points are permanently secure. Therefore, it is widely used in heavy machinery and load-bearing structures. Provides a solid guarantee for equipment safety.
Strong environmental adaptability
It can withstand extreme temperatures. It will not be brittle at minus 40°C. It will not soften even under short-term high temperatures of 300℃. The blackened surface layer has excellent UV resistance.
Not easy to chalk or fade. This makes it ideal for outdoor installations and automotive parts. It can calmly cope with most climate challenges around the world.
Excellent electrochemical compatibility
It is very safe when connected to light metals such as aluminum and magnesium alloys. Can greatly reduce the risk of galvanic corrosion. Test data shows that its corrosion impact on 6061 aluminum alloy can be reduced by more than 50% in a salt spray environment.
This feature protects the main structural materials. It is therefore an ideal connector for modern automotive and aerospace applications. Effective when used to join dissimilar materials.
Environmental protection and biosafety
Its surface treatment adopts environmentally friendly technology. The production process strictly follows the RoHS directive. The content of harmful substances in the product is less than 0.1%. Completely free of toxic hexavalent chromium.
Both substrate and coating are non-toxic and odorless. This enables use in food equipment and medical devices. Also ideal for drinking water systems. The hygiene and safety of the final product are ensured.
