Special Rivets
One of Chinese manufacturer of Special Rivets, offering excellent quality at a competitive price, is Notin. Feel free to get in touch.
In the field of mechanical manufacturing and assembly, rivets are a common fastener used to professionally connect two or more parts. According to the degree of standardization, rivets can be divided into two categories: standard rivets and non-standard rivets. The size, shape and material of standard rivets are uniformly specified, while non-standard rivets are customized according to specific needs. The following will introduce the characteristics and applications of non-standard rivets from multiple aspects.
What are non-standard rivets?
Non-standard rivets are also called special rivets. They refer to rivets that do not meet national standards or industry general standards. Their size, material, structure and other parameters are designed and manufactured according to the specific needs of customers. Due to the different connection requirements of different industries and equipment, standard rivets may not meet the requirements of certain special scenarios, so non-standard rivets came into being.
What are the characteristics of special rivets?
(1) Strong customization: Non-standard rivets can be personalized according to factors such as the use environment, stress conditions, and assembly methods to ensure that they perform well in actual applications.
(2) Diverse materials: In addition to common carbon steel and stainless steel, non-standard rivets can also be made of special materials such as aluminum alloy, copper alloy, titanium alloy, etc. to meet different corrosion resistance, strength and weight requirements.
(3) Flexible structure: The structure of non-standard rivets can be adjusted according to needs, such as head shape, stem diameter, length, etc., and can even be designed to be hollow, semi-hollow or other special shapes.

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.

Male Female Rivets
Nuote Metals is a specialzied manufacturer of male female rivets in China, The advantages of male female rivets are simple installation and low cost. Compared to other connection methods, such as welding or adhesives, male female rivets do not require specialized skills or long curing times. However, their disadvantages are also significant: the connection strength is limited, making it unsuitable for high-intensity or high-vibration environments. After long-term use, they may become loose, requiring regular inspection.

Knurled Rivets
Knurled rivets typically consist of a head, shank, and tail. The shank features a diagonal or straight knurled pattern, a machined, embossed texture that provides a better grip during installation and prevents tool slippage. The shank is cylindrical, with length and diameter varying depending on the application. Common sizes range from 3 mm to 8 mm in diameter and 5 mm to 20 mm in length. The tail may also have threads or grooves for mating with nuts or other fasteners.

Manufacturing process of special rivets
The manufacturing of non-standard rivets involves multiple links, mainly including:
1.Material selection: Select suitable metal or alloy materials according to the use environment. 2. 2.Cold heading or hot heading: Use pressure processing to form the basic shape of the rivet into the metal blank.
3.Turning or milling: Fine-process the details such as the head and stem of the rivet to ensure dimensional accuracy.
4.Surface treatment: Such as galvanizing, nickel plating, anodizing, etc. to improve corrosion resistance or aesthetics.
Advantages and limitations of special rivets
(1) Advantages: They can meet special needs, improve assembly efficiency and connection reliability, and are suitable for complex or high-demand application scenarios.
(2) Limitations: Since they are customized products, the production cost is high, the delivery cycle is relatively long, and customers are required to provide detailed technical parameters.
How to choose suitable special rivets?
(1) Clarify the needs: Determine the key parameters such as the rivet's operating environment, stress conditions, and corrosion resistance requirements.
(2) Material matching: Select the appropriate material based on actual needs to avoid over-design that leads to increased costs.
(3) Communicate with suppliers: Provide detailed technical drawings or samples to ensure that the non-standard rivets produced meet expectations.
What are the main applications of special rivets?
(1) Aerospace: Aircraft, rockets and other equipment have extremely high requirements for the weight, strength and high-temperature resistance of fasteners. Non-standard rivets can be optimized according to specific needs.
(2) Automobile manufacturing: Certain special models or high-performance vehicles may require non-standard rivets to meet the needs of lightweight or high-strength connections.
(3) Electronic equipment: Precision instruments or small electronic equipment may require micro non-standard rivets to ensure the stability and compactness of the connection.
(4) Construction industry: Some special-structured buildings or decoration projects may use non-standard rivets to meet specific installation requirements.
Market status of special rivets
With the advancement of industrial technology, more and more industries have begun to use non-standard rivets to optimize product design. At present, non-standard rivet manufacturers are mainly concentrated in the Yangtze River Delta and Pearl River Delta regions in China, and can provide a variety of customized services. Due to the high unit price of non-standard rivets, its market size is relatively small, but the demand in the high-end manufacturing field continues to grow.
Future development trends
(1) Lightweight design: With the improvement of energy-saving and environmental protection requirements, non-standard rivets made of lightweight materials will be more popular.
(2) Intelligent production: Automated equipment and digital management will further improve the production efficiency and quality stability of non-standard rivets.
(3) Wider application: Emerging industries such as new energy and robotics may drive the growth of demand for non-standard rivets.
In summary, special rivets are highly customized fasteners that can meet special needs that standard rivets cannot meet. Although its production cost is relatively high, it plays an irreplaceable role in industries such as aerospace, automobiles, and electronics. In the future, with the advancement of manufacturing technology, the application scope of non-standard rivets is expected to further expand.
