Rivets
As one of professional manufacturer in China, Notin would like to provide you Rivets. And we will offer you the best after-sale service and timely delivery.
What is a rivet?
A rivet is a permanent mechanical fastener used to join two or more materials. Rivets work by inserting a metal pin into an aligned hole and deforming the end, creating a strong, secure, and durable connection. Unlike temporary fasteners like screws, rivets do not rely on threads, but instead form a permanent connection, making them ideal for applications requiring high strength, durability, and vibration resistance.
Classification of Rivets
Rivets are typically categorized by head shape, degree of hollowness, or material.
Based on head shape, rivets can be classified as flat head rivets, round head rivets, countersunk head rivets, mushroom head rivets, universal head rivets, truss head rivets, etc.
Based on degree of hollowness, rivets can be classified as solid rivets, semi-tubular rivets, or full tubular rivets.
Based on material, rivets can be classified as brass rivets, stainless steel rivets, steel rivets, aluminum rivets, copper rivets, etc.
What surface finishes are available for rivets?
Rivet surfaces are typically treated with rust-proofing treatments, primarily electroplating, including zinc plating, nickel plating, chrome plating, tin plating, gold plating, and silver plating. Electroplating is a common rust-proofing method for rivets. It applies a layer of plating to the rivet surface through physical or chemical methods. The plating effectively prevents corrosion and rust, while also providing a certain aesthetic effect.
Another special surface treatment method is head coating. Head coating is performed after the rivet is electroplated. This allows for a variety of colors on the rivet head, achieving an aesthetically pleasing finish.
Aluminum rivets cannot be electroplated, but they can be anodized. Anodizing also allows for a variety of color options, but the unit price is higher than electroplating.
Rust-proofing the rivet surface is crucial, effectively extending the rivet's service life and ensuring a secure connection. Different rust-proofing methods are suitable for different environments and applications, so the choice should be tailored to the specific situation.

Semi Hollow Rivets
Nuote Metals is a professional rivet manufacturer located in Dongguan, China, an industrially developed city with convenient transportation and a comprehensive range of surface treatments. Semi hollow rivets are a commonly used fastener characterized by a hollow section at the shank. This design allows them to better adapt to deformation of the joined materials during the riveting process, thereby improving joint strength and reliability. Semi hollow rivets are widely used in the automotive, aviation, and shipbuilding manufacturing industries, as well as in the assembly of electronics and home appliances.

Round Head Rivets
Round head rivets feature a unique head design with a semicircular protrusion. This structure effectively distributes stress when the rivet is subjected to force, enhancing the stability of the connection. The raised head also facilitates positioning and alignment during installation. Furthermore, round head rivets offer excellent corrosion and fatigue resistance, maintaining stable performance over time in harsh environments. Looking for rivets made from China? Just feel free to contact Nuote Metals, we have more than 10 years working experience on rivets.

Powder Coated Rivets
Colored rivets, also known as powder coated rivets, are coated with powder coating on the rivet head through a high-temperature spray-painting process. The paint is evenly dried to ensure a non-fading finish. This type of rivet requires a high level of skill in baking varnish and precise color matching. After riveting, it creates a consistent and beautiful color, fully realizing its decorative effect.

Pan Head Rivets
Pan head rivets are mechanical components used to fasten or connect metal materials. They are widely used in industrial production, machinery manufacturing, auto repair, and other fields. The function of a rivet is to insert the rivet tube into the two pieces of metal being joined. The shape of the rivet head and the pipe section compress the rivet, creating a tight connection. Nuote Metals specializes in the production of Pan Head rivets. We have over 40 cold heading machines and thousands of dies, with a daily production capacity of up to 10 million rivets. We welcome custom orders based on your drawings and samples.

Painted Rivets
Painted rivets with a painted head are highly corrosion-resistant. The paint layer, typically 15-25 microns thick, effectively isolates them from moisture and chemicals. Salt spray tests show that painted rivets can resist rust for over 500 hours, three times longer than uncoated rivets. Nuote Metals are specializing these kinds of rivets, we are loated in Dongguan, China.

Mushroom Head Rivets
The name of mushroom head rivet comes from its appearance and structural characteristics. One end of the rivet is mushroom-shaped and relatively wide, providing a better compression surface and aesthetic effect. Semi-tubular mushroom head rivets have a semi-hollow design at the other end. During installation, a special tool is used to expand the hollow portion to form a secure connection. This design allows the rivet to adapt to different material thicknesses after installation, while maintaining a neat and aesthetically pleasing joint. Solid mushroom head rivets are also available, which are screw-riveted to form a mushroom-shaped head at the tail end, creating a connection that is both aesthetically pleasing and secure.

1. Ease of Installation
Rivets are fast to install, and even fully automated for high-volume applications, resulting in a simple and efficient operation process.
2. Connection Reliability
The riveting process is standardized, with strict quality control, resulting in highly stable connections. Visual inspection allows for quick verification of connection quality.
3. Vibration and Impact Resistance
Rivets connect through deformation or interference fit, providing strong clamping force and excellent vibration resistance, capable of withstanding vibration and shock.
4. Low Cost
Rivets are easy to install and can be fully automated, saving significant labor costs.
What are the advantages and disadvantages of rivets made of different materials?
Aluminum Rivets
Advantages: Lightweight, reduces overall product weight, low cost, suitable for general civilian applications.
Disadvantages: Low tensile and shear strength, unsuitable for high-strength workpieces, prone to electrochemical corrosion when in contact with metals such as stainless steel.
Stainless Steel Rivets
Advantages: Strong corrosion resistance, high hardness, suitable for high-strength workpieces (such as marine equipment)
Disadvantages: Higher cost, typically more expensive than aluminum rivets of the same specification.
Brass and Copper Rivets
Advantages: Excellent conductivity (such as connecting electronic components), good corrosion resistance.
Disadvantages: Higher cost, more difficult to process.
Steel Rivets
Advantages: High hardness, high connection reliability, and wide applicability.
Disadvantages: Compared to other materials, iron rivets are more prone to rusting.
What are the main applications of rivets?
Rivets have a wide range of uses, from small items like a pair of scissors to large items like airplanes and ships, as well as in high-precision medical applications.
Industrial Manufacturing
Rivets are used in a wide variety of industrial fields, wherever there is a need to connect two or more materials.
Electronics
Rivets secure heat sinks and chips, providing both vibration damping and noise reduction, and are widely used in the cooling systems of electronic products such as computers and mobile phones.
Automotive
Rivets are widely used to connect components of automobile bodies and chassis, such as doors and hoods. Their lightweight and corrosion-resistant properties make them an indispensable joining method in automotive manufacturing.
Aerospace
In aircraft manufacturing, rivets are used to connect different fuselage components, such as wings and tailplanes. Millions of rivets create high-strength, corrosion-resistant joints. Aluminum and titanium alloy rivets are often used to connect components of corresponding materials, ensuring stability in extreme environments.
