Back in the day, rivets were the go-to fastener for many engineering applications. From constructing bridges to assembling airplanes, these little metal pins were a mainstay in the building industry for over a century. However, as technology progressed and engineering became more complex, the use of rivets started to dwindle. So, when did they stop using rivets, and what alternatives have been developed instead?
Over the years, rivets provided a secure and reliable solution for connecting metal plates and beams. However, as machines evolved and materials became stronger, the need for a more sophisticated means of joining parts started to emerge. So, engineers began looking for new methods that could provide the required strength without compromising the integrity of the materials. This led to the development of welding, adhesives, and bolted joints, all of which have surpassed the capabilities of the traditional rivet.
Today, rivets are still used in some areas, but they are no longer considered the most efficient solution for engineering problems. As more advanced technologies are developed, it’s only a matter of time before these once ubiquitous fasteners become obsolete altogether. So, if you’re interested in the history of engineering and want to know when did they stop using rivets, read on to find out more about the alternatives that have replaced them.
History of Rivet Usage
Riveting has been used for centuries to join separate pieces of materials by means of a mechanical fastener. The earliest known rivets were used by the Egyptians, who used them to fasten together delicate pieces of jewelry. However, the metalworking techniques required to create large rivets capable of bonding larger materials together were not available until the Bronze Age.
The use of rivets became more prevalent during the Industrial Revolution, when demand for ships, railway engines and construction materials grew rapidly. Prior to welding and other modern joining techniques, rivets were considered the primary fastening method. They were used to join steel plates and iron steels and hold together structures like bridges and buildings, which were used extensively until the mid-twentieth century.
Advantages of Riveting
- Riveting is a fast and reliable method of bonding materials together.
- Riveted joints provide better load distribution and increased resistance to fatigue.
- Riveting is a permanent fastening solution and does not require maintenance or retightening.
Rivets in Modern Times
The use of rivets began diminishing as welding, adhesive bonding, and other joining methods became more common. Stainless steel bolts and screws eventually replaced the use of rivets in many applications, especially in aircraft construction, where weight savings and streamlined designs are crucial.
Today, rivets are still used in certain applications, such as road signs, pressure vessels, and the construction of some aircraft. However, they are no longer commonly used in large-scale applications and are mainly reserved for niche areas where their advantages outweigh the disadvantages.
Riveted Joints: A Strength Comparison
One commonly asked question regarding rivet usage is their strength compared to other joining methods. The following table outlines the shear strength of rivets compared to other joining methods:
| Joining Method | Metal-to-Metal Shear Strength (pounds per square inch) |
|---|---|
| Rivet Joint | 10,000 – 60,000 |
| Welded Joint | 20,000 – 40,000 |
| Mechanical Joint (Bolt) | 10,000 – 100,000 |
| Adhesive Bond Joint | 1,000 – 4,000 |
As the table shows, rivets provide a comparable level of strength to welding, with mechanical joints (bolts) providing even higher levels of strength. Adhesive bond joints provide significantly less strength than any of the other three options.
Different types of rivets used in construction
Rivets have been used in construction for centuries, dating back to Ancient Rome. They were originally made from wood or bone but have evolved to be made of metal such as iron, steel, and aluminum. Different types of rivets are used for different purposes, and below are some of the most common types of rivets used in construction:
- Solid Rivets: These are the most traditional and widely used type of rivets. The shank of a solid rivet is passed through a pre-drilled hole and then hammered on the opposite end to create a head that holds two materials together. Solid rivets are popular because they offer high strength and durability.
- Blind Rivets: These are also known as pop rivets or pull rivets. Blind rivets are used where only one side of the workpiece is accessible. They are installed from one side using a special tool that pulls the mandrel through the material, expanding the rivet on the other side to hold two materials together.
- Tubular Rivets: These are used in joints that require more flexibility. The shank of this rivet can be bent without breaking or compromising its strength. Tubular rivets are commonly used to attach straps to clothing or bags.
The shift away from rivets in construction
In the 20th century, the construction industry shifted away from using rivets in favor of welding, bolting, and adhesive bonding. Compared to riveting, these later techniques offered several advantages such as enhanced structural integrity, improved productivity, and a quicker assembly process. Welding and bolting, for example, allowed for larger steel girders to be used in buildings and bridges. Additionally, advanced technology allowed for high strength adhesives to be developed that could be used in place of rivets.
A brief comparison: Riveting vs. Welding vs. Bolting
While rivets are less common in modern construction, it’s worth noting some of the differences between riveting, welding, and bolting:
| Riveting | Welding | Bolting | |
|---|---|---|---|
| Strength | High strength, suitable for heavy-duty applications | Even higher strength than riveting, suitable for heavy-duty applications | Less strength compared to riveting and welding but still suitable for some applications |
| Difficulty | Requires skilled labor | Requires skilled labor | Requires less skilled labor |
| Productivity | Slower assembly process due to the need for precise, manual work | Fast assembly process but requires more complex machinery and safety equipment | Fast assembly process but requires torque tools and specialized bolts |
Despite the decline in popularity, rivets still remain a solid option for some applications. Their use is still prominent in the aircraft and automobile industry where they are used in sheet metal, panels, and other components that require high strength and durability.
Advancements in Fastening Technology
The evolution of fastening technology has come a long way since the time primitive humans used bone fragments, sinew or plant fibers as cords to hold objects together. The industrial revolution paved the way for new methods of attaching things together permanently. The introduction of screws, nuts and bolts proved to be a game-changer in the manufacturing industry. However, the use of rivets remained robust for a long time, especially in structures like bridges, aircraft and ships where stability was paramount. However, innovations and advancements in fastening technology have led to the phasing out of rivets.
- Aero Rivetless Nutplate Technology (ARNT)
- Adhesive bonding
- Friction Stir Welding (FSW)
Let us look at these three notable advancements in fastening technology that have replaced rivets in many applications today.
Aero Rivetless Nutplate Technology (ARNT)
Aero Rivetless Nutplate Technology (ARNT) is a method of fastening used in the aerospace industry to replace rivets. It is much lighter than typical riveting, saving considerable fuel and weight. It uses a nut plate with self-contained captive nuts that are bonded to the structure with an adhesive. This technology eliminates the need for drilling holes and riveting, thereby avoiding the associated quality issues such as mismatched holes, rivets that fail during installation, or missed installation altogether. The use of ARNT reduces manufacturing time, lowers the potential for errors, and ultimately increases the structural efficiency of the aircraft.
Adhesive bonding
The use of adhesive bonding technology has revolutionized the way manufacturers fasten materials together. Adhesive bonding is a process that joins two surfaces without using any mechanical fasteners, such as bolts, screws, or rivets. Instead, it uses an adhesive to bond the surfaces together. The adhesive creates a chemical and mechanical bond between the two surfaces. This method of fastening has several benefits, including weight reduction, vibration reduction, and improved product performance. Adhesive bonding is used extensively in automotive manufacturing, aerospace, and shipbuilding, among others.
Friction Stir Welding (FSW)
Friction Stir Welding (FSW) is a solid-state joining process that uses frictional heat and pressure to create a weld between two metals. It is an alternative to traditional welding methods, such as MIG and TIG welding. FSW does not require any filler materials, nor does it produce any fumes or emissions. It produces a strong, consistent, and high-quality weld. FSW has become a popular choice for manufacturing industries where the joining of metals is essential, including aerospace, automotive, and shipbuilding industries.
| Advancement | Benefits |
|---|---|
| Aero Rivetless Nutplate Technology (ARNT) | – Reduced fuel consumption – Lowered weight – Improved structural efficiency – Reduced manufacturing time – Eliminating quality concerns |
| Adhesive bonding | – Improved product performance – Reduced weight – Vibration reduction |
| Friction Stir Welding (FSW) | – Produces consistent and high-quality welds – No filler materials – No fumes or emissions |
These are just a few of the advancements in fastening technology that have revolutionized how manufacturers create products. The introduction of these new technologies has enabled manufacturers to produce lighter, faster, and more efficient products, making our lives safer and easier.
The switch from rivets to welding
Rivets have been the preferred method of joining metal plates since the Industrial Revolution. Riveting is a process that involves heating and hammering a metal pin (the rivet) to create a permanent bond between multiple metal plates. However, as technology progressed, new methods of joining pieces of metal emerged. One process that has become increasingly popular is welding.
- Welding is faster and more efficient – Welding involves heating two or more pieces of metal and fusing them together with a filler material. This process can be performed much faster than riveting and is more efficient in terms of material use.
- Welding creates a stronger bond – Welding produces a stronger bond between metal plates than riveting. This is because the welding process creates a continuous joint, as opposed to the intermittent bonds created by rivets.
- Welding is more versatile – Welding can be performed on a wider range of metal types and thicknesses than riveting, making it a more versatile joining method.
With all of these advantages, it’s no surprise that welding has become the preferred method of joining metal plates. While there is still a time and place for riveting, welding is now used in a wide range of industries, from construction to aerospace and beyond.
Below is a table that compares the two joining methods:
| Joining method | Advantages | Disadvantages |
|---|---|---|
| Riveting |
|
|
| Welding |

As you can see, the advantages of welding far outweigh the disadvantages, making it the preferred method of joining metal plates.
Impact of the use of rivets in industrialization
The Industrial Revolution was a period of significant technological advancement, which brought about major changes in the manufacturing process. One of the most significant developments during this period was the use of rivets. Rivets are small metal objects used to join two pieces of material together. The use of rivets made production processes quicker and easier, and it became a popular method of joining metals in many different industries.
Rivets played an important role in the building of ships, aircraft, bridges, and buildings. These industries saw immense benefits with the advent of riveting tools, which allowed them to fabricate materials quickly and efficiently. Before this innovation, construction and manufacturing were tedious and time-consuming tasks without the use of rivets. With the advent of rivets, workers could assemble materials faster, and better methods of structural design were developed.
- Rivets have influenced the transportation industry by making stronger and more efficient constructions. For example, in the railroad industry, riveting played a fundamental role in the construction of the first steam locomotives and railways. This technology helped in making the transportation of goods reliable and much faster.
- Another industry that benefited from the use of rivets was shipbuilding. Riveting allowed for the mass production of ships, which helped the industry keep up with the demand for new watercraft. Additionally, the use of rivets helped ships withstand tough weather conditions and prevent leakage problems.
- Riveting also played an important role in the construction of high rise buildings, such as skyscrapers. The use of rivets made the construction process easier, quicker, and safer, allowing buildings to be taller and more extravagant.
However, as technological advancement continues to progress, new joining techniques have been developed, rendering riveting tools less efficient. One of the significant challenges of using rivets is that they require highly skilled personnel to operate, making skilled labour more expensive. With the introduction of glue and bolt fastening, rivets’ value started to decline in the 1960s and 70s.
| Riveting method | Advantages | Disadvantages |
|---|---|---|
| Bolt fastening | Inexpensive Process | Low shear and tensile load capacity |
| Welding | Results in a permanent joint and can be used with thicknesses up to several inches. | The process can be dangerous, requires skilled labour, and is not reversible. |
| Glue joint | Can join dissimilar materials | The bond strength is lower than other methods, and temperature changes can weaken the glue. |
Despite new technologies, riveting tools remain in use today. Especially in cases where precision and strength are vital, and shock or vibration can weaken other forms of joining.

Safety concerns with the use of rivets in construction
For years, rivets were the go-to option for fastening materials in construction projects. However, as technology and innovation progressed, it became apparent that riveting had some safety concerns that needed to be addressed. Here are some of the key safety concerns associated with the use of rivets in construction:
- Structural issues: With the use of rivets, the entire structure is held together through friction. This poses a problem if the rivets are installed improperly, as this may lead to a structural instability of the building.
- Fatigue: Fatigue is common in riveted structures because of the constant vibration and wear and tear. This can weaken the metal and reduce the efficiency of the rivets, gradually leading to failure.
- Corrosion: Riveted structures are highly susceptible to corrosion, especially in areas where moisture and humidity are present. This can significantly reduce the strength of the rivets, leading to failure.
As a result of the safety concerns listed above, alternative methods such as welding and bolting have overtaken riveting as the preferred option for construction fastening. These methods have lower susceptibility to fatigue and corrosion, which reduces their chances of failure.
