A rivet is a nail-shaped object used to connect two parts (or components) with a through hole and a cap at one end. Is a kind of fastening hardware accessories, maybe a lot of people don't know, what is the material of the rivet? What is the type of rivet and what is the role? Don't worry, let's explain it for everyone, let's have a look.
rivet is what material?
There are copper, iron, aluminum, stainless steel, alloy and so on. Copper rivets are parts that use their own deformation or interference to connect riveted parts in riveting. Common ones are semi-round head rivets, flat head rivets, countersunk head rivets, semi-hollow rivets, solid rivets, female rivets, step rivets, etc. Lantern folding rivets are generally made of various grades of aluminum alloy, with good corrosion resistance, used in harsh weather environment. Lantern rivets form three folded feet during use to disperse the clamping force of the rivet on the product without damaging the riveted material. Lantern rivets can also be applied to riveting larger shapes.

The rivet top rod can be made of tungsten alloy material. Tungsten alloy rivet top bars provide maximum available density. The edges and corners of the rivet top bar are ground flat and the working surfaces are polished for ease of use. This helps to place the buck tail that appears deformed. Caution: Do not use a vice to clamp the rivet top bar unless the tip of the vice is fitted with a protective cover to prevent damage to the rivet top bar.

rivet type and what is the role?
Commonly used are R-type rivets, fan rivets, blind rivets (core rivets), tree rivets, semi-round heads, flat heads, semi-hollow rivets, solid rivets, countersunk head rivets, blind rivets, and hollow rivets, which usually use their own deformation to connect riveted parts. Generally less than 8mm with cold riveting, larger than this size with hot riveting. But there are exceptions, such as some locks on the nameplate, is the use of rivets and lock body hole interference riveting.

R-type plastic rivets are also called expansion rivets, which are composed of two parts: plastic sub-nails and female buckles. 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, the specially designed foot expands and expands after being stressed, and is firmly locked on the installed surface. It is often used to connect plastic shells, lightweight plates, insulating materials, circuit boards, or any other thin, light materials, beautiful and practical, easy to use.

The fan rivet is specially designed for manual installation. It can be pulled in through the hole of the panel or the chassis. It is made of elastomer material with good toughness and can be installed quickly even in interference assembly. The design is ingenious and has elastic function. It is not easy to slide out after being pulled in with the corresponding aperture. The fan rivet is mainly used to fix the fan, heat sink and chip of the electronic computer chassis, which has anti-vibration and noise reduction.
Core rivet is a new type of riveting fastener which is very convenient for riveting. Core rivet can show its unique advantages in a relatively narrow space or in an environment where there is no riveting gun or can not be used. Two or more connected parts can be riveted successfully by using a hammer and other utensils to strike the nail core on one side. Core striking rivets can be divided into flat round head core striking rivets and countersunk head core striking rivets according to the shape of the cap brim. According to the different material combinations, they can be divided into all aluminum core striking rivets, aluminum steel core striking rivets, all stainless steel core striking rivets, steel core striking rivets, aluminum stainless steel core striking rivets, plastic core striking rivets, etc. Core rivets do not need to use manual riveting guns or pneumatic riveting guns to rivet like core rivets. They have better riveting properties and convenience, and can be widely used in riveting of various connected parts.

Plastic tree rivets are also called inverted tooth-shaped plastic rivets and also called Christmas tree-shaped plastic rivets. The tooth-shaped sheet has good elasticity and can be directly and manually pressed and installed in the round hole of interference assembly. The tooth-shaped sheet can be adjusted and fixed according to the actual thickness and size. The design of inverted tooth-shaped rivet is that the rivet is firmly fixed on the installed surface after installation and is not easy to be pulled out. It is suitable for foam, wood and rubber, automotive interiors and other soft materials for fixed use. Plastic tree rivets have excellent insulation, fire resistance, non-magnetic, heat insulation, light weight, high temperature resistance, high strength, corrosion resistance, and are widely used in various industrial fields.

The types of pulling rivets can be roughly divided into open type, closed type, double drum type and single drum type series. The following is a brief description of their respective models. Countersunk type blind rivet: for the riveting of riveted parts with smooth and beautiful surface. Double drum type blind rivet: when riveting, the nail core pulls the end of the rivet body into a double drum shape, clamps the two structural parts to be riveted, and can reduce the pressure acting on the surface of the structural parts. Uses: Mainly used for riveting various thin structural parts in various vehicles, ships, construction, machinery, electronics and other industries. Large brim blind rivet: Compared with ordinary blind rivet, the diameter of the aluminum cap of the rivet is significantly larger. When the rivet is riveted with the connecting piece, it has a larger contact area and a stronger supporting surface, which can enhance the torque strength and can withstand higher radial tension. Applicable industry: suitable for fastening soft, fragile surface material and large hole, increase the brim diameter for soft material has special protection application. Closed core rivets: specially designed to wrap the mandrel head after riveting, it is very suitable for many applications with waterproof requirements. With high shear, anti-vibration, high pressure resistance.

All-aluminum blind rivets The rivet body of the rivet is also made of high-quality aluminum wire, which is beautiful and durable after riveting and will never rust: compared with ordinary blind rivets, the rivet riveting strength is lower, and it is suitable for connectors with softer materials. Open Stainless Steel Rivets: This rivet is the choice for high tensile, corrosion-resistant demands. Semi-round head rivets are mainly used for riveting occasions with large lateral loads, and are the most widely used. Flat cone head rivets due to the nail head hypertrophy, can resist corrosion, often used in the hull, boiler water tank and other strong corrosion riveting occasions.

Flat head rivet

Countersunk, semi-countersunk, 1200 countersunk and semi-countersunk rivets are mainly used for riveting occasions where the surface needs to be smooth and the load is not large. Flat head rivets are used for riveting applications subject to general loads. Flat head, flat round head rivets are mainly used for sheet metal or leather, canvas, wood and other non-metallic materials riveting occasions. Large flat head rivets are mainly used for riveting occasions of non-metallic materials. Semi-hollow rivets are mainly used for riveting occasions with little load. Headless rivets are mainly used for riveting occasions of non-metallic materials. Hollow rivets are light in weight and weak in nail head, and are used for riveting occasions of non-metallic materials with little load. Tubular rivets are used for load-free riveting of non-metallic materials. Sign rivets are mainly used for riveting nameplates on machines, equipment, etc.

Blind rivets are a kind of rivets for single-sided riveting, but special tools must be used-rivet gun (manual, electric, pneumatic) for riveting. This kind of rivets is especially suitable for riveting occasions where it is inconvenient to use ordinary rivets (riveting from both sides), so it is widely used in construction, automobiles, ships, aircraft, machines, electrical appliances, furniture and other products. Among them, the open type flat round head blind rivet is the most widely used, the countersunk head blind rivet is suitable for the performance of the need for smooth riveting occasions, closed type blind rivet is suitable for the requirements with higher load and has a certain sealing performance of the riveting occasions.
