Closed End vs Open End Rivet - Which Pop Rivets Are Better ?

By RIVMATE /March 12,2024 Tite: Closed end vs Open end rivet

Are you confused about open end rivet and closed end rivet? Do you understand the difference between them? In this article, we will guide you through their meanings, benefits, applications, and most importantly, the differences between open end rivet and closed end rivet. We will help you choose the best pop rivet for your project, so let’s dig deeper!

All About Open End Rivets

When the POP brand emerged, the Open end rivet was marketed as one of the first products. It is no exaggeration to say that open end rivets are the most popular pop rivets, and they have been used in construction, machinery, automotive, furniture and other fields. Because open end rivets can be used to make tight connections at the lowest possible economic cost, they guarantee the safety of the project. Since engineers discovered the advantages of open end rivets, more and more double-sided connections have been replaced by blind rivets. But what are they? Can you use them in your projects? Let’s find out.

What is An Open End Pop Rivet?

An open end rivet is a rivet with a hollow body. open end rivets are the most common type of rivet and the cheapest type of pop rivet. There are a variety of metals that can be used as raw materials for open end rivets, such as aluminum, carbon steel, stainless steel, and steel. open end rivets are ideal for use in joints that do not need to be subjected to excessive loads, such as decorative metal applications and other lightweight installations. there are also a variety of head styles available for open end rivets, including dome head, large head, and large end rivet. Open end rivet is available in a variety of head styles including dome head, large flange and csk head.

Advantages of Open End Rivets

Coming to the part you are most concerned about.Benefits of Open rivet.Open end rivets have a lot of benefits and that’s why they are widely used:

Open end blind rivets provide a reliable, high strength connection. They can withstand high tensile and shear forces.
The installation process is relatively simple and fast. Installation of rivets can be easily accomplished using specialized riveting tools.
Open end blind rivets can be installed on one side compared to other connection methods such as bolts.
It is suitable for joining between different types of materials, including metal-to-metal and metal-to-non-metal connections.

Disadvantages of Open End Rivets

Although open end rivets are the most widely used blind rivets, they also have some disadvantages. In some cases, open rivet is not suitable.

In terms of strength, open end rivets are not as strong. Therefore, open rivet is not suitable for connecting joints with high load bearing capacity.
Another disadvantage of open end rivet is that it does not have good sealing properties. This means that in applications where there is a need to prevent penetration of liquids, gases or contaminants, open end blind rivets may not provide the desired seal.
Open end blind rivets leave a visible open head after installation, which can affect the aesthetic appearance of the joint.

Application of Open End Rivets

Open rivet has the advantage of low price and easy installation compared to closed rivets and structural rivets. Therefore they are widely used in conventional joints.

In construction and building structures, open end blind rivets are commonly used to join metal components such as steel structures, steel beams and metal sheets. They can be used to join window and door frames, roof structures, steel frames and more.
Open rivet can provide a stable connection, which is why they are widely used to join circuit boards, radiators, chassis and other electronic equipment components.
Open end blind rivets are commonly used to join furniture frames, chair seats, handles and other components. Open end blind rivets provide a simple, effective connection that makes furniture assembly easier and faster.

All About Closed End Rivets

Now, if you read the last part, you might be aware of the pros and cons of open end rivet. Here we’ll take a look at another more common type of pop rivet, the closed end rivet.

Closed end rivets revolutionize the functionality of the project. Equipping the closed end rivet makes the overall project water and dust resistant. They have completely taken the place of open rivet for specific applications, especially where waterproofing is required. These closed end rivet are more environmentally friendly and efficient than any other connection. They can cost very little and will be more beneficial in the long run.

Before we explore why you should buy these particular waterproof rivets, let us first understand what they are.

Are Closed End Rivets Waterproof?

Closed end rivet provides some water resistance due to its closed head design. It is suitable for applications that require use in wet or humid environments. However, if you think that the closed end rivet is completely waterproof, you are wrong. Although closed end rivets provide good waterproof performance, leakage may still occur under extreme water pressure or prolonged immersion. Therefore, you need to take extra measures (with rubber gaskets) for special waterproofing requirements.

If you want to know more about waterproof rivets. You can read this article “are waterproof rivet watertight“.

What is A Closed End Rivet?

The Closed end rivet is a pop rivet with a cupped head construction. it has a mandrel that passes through the center. the unique cupped head of the Closed end rivet prevents water and dirt from seeping through the body of the rivet. Some people who use the closed end rivet think it is completely waterproof, but in fact, this is not entirely true. If you want to achieve full waterproofness, you need to use it with a rubber gasket.The closed end rivet comes in two head styles: dome head and csk head.

Advantages of Closed End Rivets

Sealed Blind Rivets provide a reliable, high strength connection.
The closed rivet head design provides excellent sealing performance. It can effectively prevent the penetration of liquids, gases or impurities.
The closed construction of the Sealed Blind Rivet helps provide good corrosion and rust resistance.
Closed end blind rivets leave virtually no raised heads or visible joint marks after installation, giving the joint a clean, attractive appearance.

Disadvantages of Closed End Rivets

There are not many disadvantages of closed end rivets as compared to open rivets. Yes, it is what you think.
Closed end rivet has higher manufacturing and material costs which makes it relatively expensive.
Often not removable after installation.Closed end rivets, once installed, cannot be unriveted from the attachment surface.

Application of Closed End Rivets

When we say that the closed end rivet and the bulb tite rivet are two of the most watertight blind rivets available, we mean it. the closed end rivet’s functionality supersedes many other attachment methods.
Let’s explore the exceptional features that make the closed end rivet perfect for waterproofing applications and ideal for commercial use.

Automotive manufacturing and aircraft manufacturing have pioneered the use of CLOSED END RIVETS for their superior performance. Initially, closed end rivets were limited to the joining of marine parts, but slowly their application has expanded. From chassis connections to door assemblies, they are everywhere.

Closed end rivets are very popular in automotive manufacturing. They replace traditional welding. Closed end rivets can be seen in body and chassis connections such as doors, hoods, body frames and other applications. Its high strength connection, sealing performance and corrosion resistance make it an important connecting element in automobile manufacturing.
The connection of aircraft structures such as wings, fuselages, tails and other components is another important use of closed end rivet. Their strength and sealing properties are essential to ensure the safety of aircraft structures and prevent the penetration of liquids or gases.

Due to closed end rivet’s excellent waterproof and dustproof characteristics. They are used in a variety of applications.

Pressure vessels and piping systems demonstrate the excellent sealing performance and corrosion resistance of closed end rivet.
Closed end rivet is used as an important part for connecting circuit boards, heat sinks, chassis and other components.
Closed end rivet has made a significant impact in furniture manufacturing. From frames, armrests and seats to the attachment of other components. One of the most common connections in furniture manufacturing is closed end rivet riveting.
