There are many kinds of rivets, and there can be a variety of classification methods according to different standards such as shape, use, and material. Here are some common types of rivets:
First, classification by shape
Half round head rivet: mainly used for riveting under large lateral load, the most widely used.
Flat head rivet: used for riveting under general load.
Countersunk head rivets: mainly used for riveting occasions where the surface needs to be smooth and the load is not large.
Oval head rivets: mainly used for metal sheet or leather, canvas, wood and other non-metallic materials riveting occasions.
Flat cone head rivets: due to the fat of the nail head, corrosion resistance, often used in ship hull, boiler water tank and other strong corrosion riveting occasions.
Tubular rivet: Used for non-metallic materials without load riveting occasions.
Second, classification by use
Boiler rivets: specially used for riveting high temperature and high pressure equipment such as boilers.
Steel structure rivets: Used for riveting steel structures, with high strength and corrosion resistance.
Plate rivets: mainly used for riveting machines, equipment and other nameplates.
Third, by material classification
Steel rivets: made of steel, with high strength and hardness.
Aluminum rivets: made of aluminum alloy, with light weight, corrosion resistance and other characteristics.
Copper rivets: made of copper, with good electrical conductivity and corrosion resistance.
Fourth, other special types of rivets
Core-pulling rivet: A type of rivet used for single-sided riveting, which must be riveted using a special tool – a riveting gun. It is especially suitable for riveting occasions that are inconvenient to use ordinary rivets (riveted from both sides), and is widely used in buildings, automobiles, ships, aircraft, machines, electrical appliances, furniture and other products.
Core rivet: another type of single-sided riveting rivet, riveting with a hand hammer to hit the head of the rivet to expose the core, so that it is flush with the end face of the nail head, that is, to complete the riveting operation. Suitable for riveting occasions where it is inconvenient to use ordinary rivets or core-pulling rivets.
R-type plastic rivets: also known as expansion rivets, which are composed of two parts: plastic nail and female buckle. Installation without the use of installation tools, through the special design of the foot force after expansion, firmly locked in the installation surface. It is often used to connect thin materials such as plastic shells and lightweight plates.
Fan rivets: Designed for manual installation, pull in through the holes in the paneling or underframe. Made of elastomer material, it has good toughness, anti-vibration and noise reduction functions. It is mainly used to fix the fan, heat sink and chip in electronic computer case.
Plastic tree rivets: also known as tooth shaped plastic rivets or Christmas tree plastic rivets. The tooth shape sheet can be fixed according to the actual thickness and size, and is firmly fixed on the installed surface after installation, which is not easy to be pulled out. Suitable for fixing between foam, wood, rubber and other soft materials.
To sum up, there are a wide variety of rivets, each of which has its own specific application scenarios and advantages. When selecting rivets, it is necessary to comprehensively consider the specific riveting needs, material type and working environment.
