What are rivets for

A rivet is a nin-shaped object used to connect two parts (or members) with a cap at one end with a pass hole. In riveting, the parts being riveted are joined by self-deformation or interference. There are many kinds of rivets, and they are not limited to any form. Rivets are usually applied to the joint riveting between objects, which usually requires the use of specific special tools to operate. The types of rivets are divided into many kinds, such as half round head rivets, flat cone head rivets, countersunk head rivets, half countersunk head rivets, flat head rivets, hollow rivets, tubular rivets, label rivets, etc., in response to different operating needs.

Half round head rivet: mainly used for riveting with large lateral load, the most widely used.

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.

Countersunk head, 1200 countersunk head rivets: mainly used for riveting occasions where the surface must be smooth and the load is not large.

Semi-countersunk head, 1200 semi-countersunk head rivets: mainly used for riveting occasions where the surface must be smooth and the load is not large.

Flat head rivet: used for riveting with general load.

Flat head, oval head rivets: mainly used for metal sheet or leather, canvas, wood and other non-metallic materials riveting occasions.

Large flat head rivets: mainly used for riveting non-metallic materials.

Semi-hollow rivet: mainly used for riveting occasions with small load.

Headless rivets: mainly used for riveting non-metallic materials.

Hollow rivet: light weight, weak nail head, used for riveting non-metallic materials with small load.

Tubular rivet: Used for non-metallic materials without load riveting occasions.

Plate rivets: mainly used for riveting machines, equipment and other nameplates.

Rivet: The type can be roughly divided into open mouth, closed type, double drum type, single drum series, the following models for a simple description.

Countersunk core rivets: riveting of riveted parts that require smooth and beautiful surfaces after riveting.

Double drum core rivet: When riveting, the core will pull the end of the riveting body into a double drum shape, clamping the two structural parts to be riveted, and can reduce the pressure on the surface of the structural parts. Usage: Mainly used in various vehicles, ships, construction, machinery, electronics and other industries riveting various thin structural parts.

Large brim core-pulling rivet: the rivet and ordinary core-pulling rivet compared to its aluminum cap diameter is significantly larger, the rivet when riveted with the connector, has a larger contact area, has a stronger support surface to enhance the torque strength, can withstand higher radial tension. Applicable industry: Suitable for tight soft, fragile surface materials and extra-large holes, increasing the diameter of the hat rim has special protection applications for soft materials.

Closed core-pulling rivets: Designed to wrap the mandrel head after riveting, ideal for many applications that require waterproofing. With high shear force, anti-vibration, anti-high pressure.

Core-pulling rivet: It is a kind of rivet used for single-sided riveting, but it must be riveted using a special tool – a riveting gun (manual, electric, and moving). This kind of rivets is especially suitable for riveting occasions that are inconvenient to use ordinary rivets (riveted from both sides), so it is widely used in construction, automobiles, ships, aircraft, machinery, electrical appliances, furniture and other products. Among them, the open-mouth oval head core-pulling rivet is the most widely used, the countersunk head core-pulling rivet is suitable for the riveting occasion that needs to be smooth, and the closed type core-pulling rivet is suitable for the riveting occasion that requires a higher load and has a certain sealing performance.

Core rivet is another type of single riveted rivet, riveting, with a hand hammer to hit the head of the rivet to reveal the core, so that it is flush with the end face of the head, that is, to complete the riveting operation, which is very convenient, especially suitable for the inconvenience of using ordinary rivets (riveted from both sides) or core rivet: (lack of a riveting gun) riveting occasions. Usually used cylindrical head core riveting, countersunk head core riveting is suitable for the surface of the need for smooth riveting occasions.

R-type plastic rivets: also known as expansion rivets, which are composed of two parts: plastic nail and female buckle. It does not need to use installation tools during installation, the installation base is placed in a smooth hole, and then the head is pressed, and the specially designed foot expands and supports after being stressed, and is firmly locked on the installed surface. It is often used to connect plastic shells, lightweight plates, insulation materials, circuit boards, or any other thin, lightweight materials, beautiful and practical, easy to use.

Fan rivets: Designed for manual installation by pulling in through the holes in the paneling or underframe, made of elastomer material with good toughness and quick installation even in interference assembly. Smart design with elastic function with the corresponding aperture is not easy to slide out, fan rivets are mainly used in electronic computer chassis fan, heat sink and chip fixed between the use, with anti-vibration, reduce noise.

Core rivets: It is a new riveting fastener that is very convenient for riveting, and core rivets can show their unique advantages in a relatively small space or in an environment where there is no riveting gun or a riveting gun can not be used. Two or more connected pieces can be riveted successfully by hitting the nail core with a hammer and other objects on one side. Core rivets can be divided into oval head core rivets and countersunk head core rivets according to the shape of the brim of the nail hat. According to the different material combination, it can be divided into aluminum core rivets, aluminum steel core rivets, stainless steel core rivets, steel core rivets, aluminum stainless steel core rivets, plastic core rivets, etc. Core rivet does not have to use a manual rivet gun or a pneumatic rivet gun to rivet like a core rivet, and has better riveting and convenience, and can be widely used in the riveting of various connected parts.

Plastic tree rivet: Also known as the Christmas tree type plastic rivets, tooth sheet good elasticity can be directly installed in the circular hole of interference assembly manually, tooth sheet can be fixed according to the actual thickness and size adjustment, the design of the tooth type is that the rivets are firmly fixed on the installed surface after installation, not easy to be pulled out, suitable for foam, wood, rubber, Automotive interior and other soft materials for fixed use. Plastic tree rivets have excellent insulation, fire performance, non-magnetic, heat insulation, light weight, high temperature resistance, high strength, corrosion resistance, widely used in various industrial fields.

Aluminum core-pulling rivets: The riveting body is also made of high-quality aluminum wire, beautiful and durable after riveting will never appear rust phenomenon: compared with ordinary rivets, rivet riveting strength is low, suitable for the material is soft connection. Open stainless steel rivet: This rivet is a high tensile demand, corrosion resistant choice.
