We will also cover their wide range of applications, compare riveting to welding, and help you choose the right rivet for your job. You will understand why rivets are a tenacious and essential part of modern engineering and craftsmanship by the end of it.
What Is A Rivet And How Does It Work?
Rivets are mechanical fasteners that join two or more materials together in a permanent, vibration-resistant manner. The standard rivet consists of a cylindrical body with a pre-formed head on one end. During installation, the rivet is inserted into pre-aligned holes in the materials, and the other end—the tail—is deformed by hammering, pressing, or pulling. This deformation creates a second head, which is sometimes referred to as the “shop head” or “buck-tail,” that positively locks the materials together.
Rivets are effective at transferring both shear and tensile loads through a joint and are suitable to high-strength and long-life applications. They are particularly appropriate for vibrational environments, where conventional threaded fasteners might work loose over time. Captivating methods vary: solid rivets are secured by physically deforming the tail, typically with a hammer or hydraulic press, while blind rivets use a mandrel to expand the rivet from one available side—ideal for uses with limited rear access.
Used for centuries to build ships and armor, rivets saw a revolutionary change during the Industrial Revolution and remain a key element in manufacturing processes today. From aircraft to construction and automotive industries, rivets are still a budget-friendly, tested-and-proven fastening solution.
Materials Used For Rivets
The choice of rivet material is a critical factor in determining its strength, corrosion resistance, and overall suitability for a given application. From lightweight aluminum to corrosion-resistant stainless steel, each material offers distinct advantages tailored to specific performance requirements.
Aluminum
Aluminum rivets are corrosion-resistant, lightweight, and simple to use, making them well suited for use in weight-sensitive industries such as the automotive and aerospace industries. While not as strong as steel, aluminum rivets do have a very high strength-to-weight ratio and will perform admirably under stressed conditions that are open to the elements because they resist rust well. However, they might be less suitable for applications with heavy stresses where maximum life is desired.
Stainless Steel
Stainless steel rivets offer excellent strength and corrosion resistivity and can be used in high-performance applications such as marine, aerospace, construction, industrial machinery, and medical devices. They come in various grades, and they perform well in harsh conditions such as exposure to seawater and high/low temperatures. The hardness makes them long-lasting but also causes installation problems compared to rivets constructed from less hard materials.
Copper
Copper rivets provide superior electrical conductivity and resistance to corrosion, making them the preferred option for electrical applications, roofing, and decorative purposes such as leatherwork and jewelry.Although not the best choice for high-strength uses as they are soft, their malleability allows them to be easily installed, and they naturally age to develop a gorgeous patina—enhancing functional and artistic value.
Steel
Steel rivets are extremely durable and robust and can be used under heavy-duty conditions in construction, automobile, railway, and machinery industries. Low-carbon steel is especially suitable for rivets due to their malleability and ability to clinch well and hence are easily accessible for use. High-carbon steel rivets are less ductile and require more material and hence turn out to be less suitable for normal riveting needs. Steel rivets are used in most load-bearing structural joints.
Brass
Brass rivets have excellent corrosion resistance and an attractive finish, making them popular where decorative details are needed. They are conductive, flexible, and easy to use, and find frequent applications in electrical equipment, musical instruments, and leather products. Because they have very good resistance to tarnishing and low friction, brass rivets are spark-free, making them extremely well-suited for use in gas appliances.
What Are The Different Types Of Rivets?
Rivets are available in a variety of types, each tailored to particular uses and installation techniques. Knowing the distinctions between them allows you to choose the most suitable option for your specific requirements.
Blind Rivets
Blind rivets or pop rivets are used where the access is single-sided for the material. Blind rivets consist of a hollow mandrel and rivet body; when installed, the mandrel is pulled through the rivet body, and the body expands to hold the materials in position. The mandrel is snapped off at one point after the securement, with a smooth, finished appearance. Usually made of aluminum, stainless steel, or steel, blind rivets are driven using handheld or pneumatic rivet guns without backside access. They are therefore particularly ideal for small areas and ideally appropriate for high-volume, high-speed manufacturing.
They are applied in wide usage within sheet metal assembly, auto panel joining, HVAC duct, and electronic housing assembly applications.
Solid Rivets
The most robust rivet is the solid rivet, which is made from a single solid piece of material with a pre-established head. During installation, the tail end of the shaft is deformed to form a second head, which firmly clamps the materials together.Solid rivets are typically constructed of steel, aluminum, or copper and offer outstanding tensile and shear strength. This deformation process compresses the materials being joined, forming a joint that is highly resistant to vibration and fatigue and is therefore acceptable for long-term structural integrity.
The installation of solid rivets requires access to both sides of the assembly. The rivet is placed into a pre-drilled hole, and the tail is shaped by hammering, using a rivet gun, or applying a hydraulic press.This process generally needs skilled labor for proper alignment and a tight fit. Due to their unmatched durability, solid rivets are employed intensively in heavy-duty and structural applications such as railway construction, bridges, aircraft fuselages, high-rise buildings, and industrial machinery. They are also favored for their reliability, corrosion resistance (depending on material), and economy in large permanent installations.
Tubular Rivets
Tubular rivets have a partially hollow shaft, which distinguishes them from solid rivets. The hollow portion facilitates easier deformation as they are driven in, so they are most suitable for light-duty application where only moderate strength is required. The structure has a solid section near the head, and the hollow end is flared or rolled to create a second head when driven in. Brass, aluminum, and steel are common materials, providing good strength with workability.
Tubular rivets are set using a rivet setter or press with less force applied than that of solid rivets and therefore are suited to softer or thinner materials like plastic or leather. They are regularly used in furniture production, electronics, and leather products.
Drive Rivets
Drive rivets are a type of blind rivet that is made for simple and quick installation through driving a central pin into the body of the rivet. In doing this, the rivet is forced outward and seizes tightly on the surrounding material with a snug, strong joint. There is a hollow body and a drive pin that makes up all drive rivets. When the pin is driven, it forces the rivet body outward to firmly lock the materials in place.Typically made of aluminum or steel, drive rivets find a balance between usability, performance, and strength. Their easy installation and dependability make them an easy answer to fast single-sided access needs without jeopardizing the strength of the joint.
Installation is accomplished from only a pre-drilled hole and a plain hammer, with no need for any special tools or working from the reverse side of the workpiece. These render drive rivets highly appealing for do-it-yourself application and quick on-site repair. They are typically applied on building sites by fixing nameplates, signs, or light panels. They are also applied in automotive repair work and temporary assembly.
Split Rivets
Split rivets or bifurcated rivets possess a shaft that is bifurcated into two prongs at the end. Upon being installed, the prongs diverge and curl over to bite into the material in order to form a strong joint. The configuration allows for the rivet to drill through weak materials—wood, leather, or soft plastics—without pre-drilled holes. Brass or steel is generally employed to produce split rivets. Split rivets are best suited for applications that require low to moderate strength.
The installation is simple: the rivet is driven into the material, and prongs are spread using a hammer or rivet setter, compressing the rivet against the material. It is especially useful in soft or porous material and is commonly used in leatherworking (e.g., saddlery, belts), bookbinding, and domestic repair, such as attaching handles to wooden boxes or furniture.
Self-Piercing Rivets
Self-piercing rivets (SPRs) are advanced fasteners that penetrate the material at installation, doing away with pre-drilled holes. Semi-tubular in shape and traditionally made of high-strength steel, SPRs penetrate the top surface of the material and flare into the bottom surface without breaking through it. This creates a strong, interlocked joint without compromising the structural integrity of the materials being formed into the joint. The design is especially suitable for thin, lightweight materials like aluminum and thin steel.
Installation of SPRs is done through the application of specialist hydraulic or pneumatic machines to generate the force to pierce and form the joint. It is a highly automated process, so SPRs are ideally suited to high-speed precision assembly lines. They are therefore widely used in the automotive industry for joining sheet metal in body cars, appliances, and electronics.
Flush Rivets
Flush rivets, also known as countersunk rivets, are designed particularly to sit flush against the surface of the material, providing a flat and aerodynamic finish. With a tapered head, they neatly fit into a countersunk hole so that the rivet surface lies perfectly flush with the surrounding material. Flush rivets are generally made of aluminum or stainless steel and make tight, smooth joints that are crucial for applications where appearance and performance are both essential.
Flush rivets require extremely precise countersunk holes and two-sided access to the workpiece. The tail end is bent, with or without the aid of a press or a rivet gun, to securely fasten the joint without compromising the flush profile. It requires high accuracy in developing the smooth finish needed. Flush rivets have widespread application within the aerospace sector in aircraft wings and skin, where drag aerodynamics must be minimized, and for high-quality furniture and architectural panels because of their aesthetic beauty.
Friction Lock Rivets
Friction lock rivets keep material in place by a close interference fit within the hole and are particularly adapted to vibration-resistant, light connections. They consist of a grooved or knurled shaft which compresses surrounding material by friction on driving. Made of aluminum or titanium, they offer lightness without too large a compromise in strength for light application of loads.
Installation is accomplished by punching the rivet through a pre-drilled hole and holding it in place with a pull-through or push-in mechanism. The high-speed operation is generally possible with a rivet gun only and is not accessed on the workpiece back side. Friction lock rivets are used extensively in aerospace on non-structural parts like interior panels, and electronic equipment to assemble lightweight assemblies.

What Are Rivets Used For?
Rivets serve a very utilitarian role and are extensively employed in a number of areas. Their fundamental function is to secure two or more pieces of metal or wood tightly and firmly in position. They offer superior strength and stability compared to screws of equivalent size.
Aerospace Industry
In aerospace construction, rivets are employed to join aircraft structures like the frame, wings, and fuselage. Due to their aerodynamic form and light strength, flush rivets and friction-lock rivets are widely used. Their reliability withstanding high-vibration conditions renders them essential to guaranteeing structural integrity.
Aircraft manufacturing requires hard, strong, and uniform materials. But if these materials are not reliably brought together—especially in hard-to-reach areas—the entire structure could be compromised. That is why riveting is as important as welding, brazing, and bolting. Rivets are particularly valuable to use in connecting aluminum alloys, which cannot be welded easily. They produce neat, appealing, durable joints that also help to reduce the overall weight of an aircraft. In aircraft construction or repair, where space within the back side of a structure is limited or zero, riveting is generally the optimum—or even only—solution.
Automotive Industry
In automotive manufacturing, rivets are an integral part in assembling such parts as chassis frames, body panels, and other structural parts. They are suited best to fasten materials like steel and aluminum. Owing to their high vibration and fatigue resistance, rivets create high-strength, durable joints, which help the industry focus on lightweight construction and long-term strength.
Jewelry Industry
Professional jewelry craftsmen and beginners alike tend to employ riveting as a main technique of cold joining in jewelry crafting. With some metal working skills, instructional instructions, and equipment that are within reach of most, artists can successfully couple metals without heat. Riveting is gaining popularity because it offers a simple yet reliable way of coupling multiple metal parts without welding, thereby widening artistic freedom and enhancing the quality of artworks.
Home Building
You may have noticed rivets around your home, both inside and out, that previously went unnoticed. These rivets are often used to fasten fiberglass roofing panels, so if your roof uses this material, they help hold it securely in place. Rivets also provide a more dependable fastening method than nails when installing gutters by firmly securing metal sheets. Further, rivets are applied heavily in building shutters, windbreaks, door frames, and straps and have a crucial role to play in maintaining the structures together.
Sports
Rivets are utilized in sporting equipment like bicycles, skateboards, and climbing gear to provide high tensile strength. They are ideally suited for high-performance equipment that must be safe and light in weight owing to their ability to create strong light joints.
Riveting Vs. Welding
Riveting and welding both create permanent, strong joints, but they serve different purposes. Which method is better depends on the specific application and requirements.
| Aspect | Riveting | Welding |
| Materials | Suitable for joining dissimilar and heat-sensitive materials without altering metal properties | Suitable for similar or compatible materials; high heat may affect material properties |
| Cost | Simple equipment, lower labor costs, ideal for small to medium projects | Expensive equipment, requires skilled operators, high initial investment |
| Applications | Ideal for flexible, corrosion-resistant, and easily maintainable joints | Suitable for heavy-duty, high-strength, and permanent connections |
| Speed | Quick installation with minimal preparation, suitable for high-volume production | Faster for large-scale projects but requires extensive preparation and finishing |
| Safety | Relatively safe to operate, suitable for non-professionals | Involves high heat and pressure; requires strict safety measures and professional training |
How To Choose The Right Rivet For Your Application?
Choosing the correct rivet involves several considerations:
- Identify Material Compatibility: Choose a rivet material compatible with or augmenting the materials to be assembled to prevent corrosion or galvanic reaction.
- Determine Load Requirements: Identify the shear and tensile loads the joint will see. Solid rivets are best where there are high loads, while blind or tubular rivets would be best for light applications.
- Bear Accessibility in Mind: Use blind rivets when there is only access on one side. Structural applications with two methods of access use solid or flush rivets.
- Evaluate Environmental Conditions: Apply resistant materials to corrosion like stainless steel or brass for use outdoors or in marine applications.
- Check Aesthetic Requirements: For aesthetically exposed joints like furniture or jewelry, use flush or decorative rivets for a finished look.
- Select Proper Size: Ensure that the rivet diameter and length are suitable for the material thickness to avoid loose joints or damage.
- Trial Installation Procedure: Check you have the tools and techniques required for the rivet being used.

FAQs
What Is Stronger Rivets Or Screws?
Rivets offer superior strength and stability, especially in shear-heavy or high-vibration environments. They form permanent, secure joints, making them ideal for aerospace, construction, and heavy machinery. Unlike screws, rivets won’t loosen over time, though they aren’t reusable. TEK screws, with a single-headed design, may loosen under prolonged vibration—such as during transportation—making rivets the preferred choice for long-term structural integrity.
What Is The Strongest Type Of Rivet?
The strongest type of rivet is the solid rivet, known for its exceptional shear and tensile strength. Stainless steel rivets paired with stainless steel or steel mandrels offer extremely high strength, while steel rivets with steel mandrels are equally robust.
Should I Use Aluminum Or Steel Rivets?
Steel rivets are stronger than aluminum rivets, but aluminum and stainless steel solid rivets offer better corrosion resistance. Aluminum rivets are lightweight and corrosion-resistant, suitable for softer materials, and easy to install but have lower strength. Steel rivets are ideal for heavy-duty structures, though they are heavier and more prone to corrosion.
Why Does Rivet Have A Tail?
The tail of a rivet exists because during installation, it is deformed to form a second head, called the “shop head” or “buck-tail,” which tightly clamps the materials together to ensure a strong and permanent connection. This deformation provides additional fastening force, preventing loosening from long-term use or vibration. It is especially effective in high-vibration environments such as automotive and aerospace applications, significantly enhancing the durability of the joint.
Why Do Rivets Fail?
Rivets bear shear, tensile, and combined loads. Excessive shear can cause breakage, while tensile loads may lead to various failure modes. Major causes of failure include overload, corrosion, fatigue, and improper installation. Incorrect sizing or incomplete deformation reduces firmness, and incompatible materials can cause electrochemical corrosion, compromising joint reliability.
