Hey there! As a supplier of closed blind rivets, I've seen firsthand the growing interest in these little fasteners and how they stack up against traditional rivets. So, let's dive right in and take a closer look at how closed blind rivets compare to their traditional counterparts.
What Are Closed Blind Rivets and Traditional Rivets?
First off, let's clarify what we're talking about. Traditional rivets are the old - school fasteners you've probably seen in various metalwork and construction projects for ages. They usually consist of a smooth, cylindrical shaft with a head on one end. To install a traditional rivet, you need access to both sides of the material you're joining. You place the rivet in a pre - drilled hole, and then use a rivet gun or hammer to deform the end opposite the head, creating a second head that holds the materials together.
On the other hand, closed blind rivets, like the Closed Core - pulling Rivet and Closed Core Rivet, are designed for situations where you only have access to one side of the material. They have a tubular body with a mandrel running through the center. When you pull on the mandrel using a special rivet gun, the body of the rivet expands and forms a bulge on the blind side, creating a strong connection. There's also the Lantern Type Blind Rivet, which has a unique shape that offers different installation and performance characteristics.
Installation
One of the biggest differences between closed blind rivets and traditional rivets is the installation process. With traditional rivets, as I mentioned earlier, you need access to both sides of the joint. This can be a real pain in many applications, especially when working on large structures or in tight spaces. For example, if you're trying to join two metal panels on the inside of a machine, getting to the backside of the panels might be nearly impossible.
Closed blind rivets, however, are a game - changer in terms of installation. You can install them from one side only, which saves a ton of time and effort. All you need is a rivet gun and the rivet itself. You insert the rivet into the pre - drilled hole, pull the trigger on the rivet gun, and the rivet sets in seconds. This makes them ideal for applications where double - sided access is limited, such as in automotive bodywork, aerospace components, and even some types of furniture assembly.
Strength and Durability
When it comes to strength, both closed blind rivets and traditional rivets can provide a solid connection. Traditional rivets have been around for so long because they're reliable and can withstand a good amount of stress. They form a very tight bond between the materials, and if installed correctly, can last for a long time.
Closed blind rivets, on the other hand, have come a long way in terms of strength. Modern closed blind rivets are designed to offer high shear and tensile strength. The closed design of these rivets also helps to prevent corrosion and leakage. For example, in applications where you need to seal a joint to keep out water or other fluids, closed blind rivets are a great choice. They can create a watertight and airtight seal, which is something traditional rivets might struggle with.
Cost
Cost is always a factor when choosing between different fasteners. Traditional rivets are generally less expensive than closed blind rivets. This is because they're simpler in design and have been mass - produced for a long time. The tools required to install traditional rivets are also often more basic and less expensive.
However, when you factor in the cost of labor and the time saved with closed blind rivets, the equation can change. Since closed blind rivets are quicker and easier to install, you can save on labor costs in the long run. Also, in some applications where the performance benefits of closed blind rivets are crucial, the extra cost might be well worth it.
Aesthetics
Aesthetics can also play a role in the choice between closed blind rivets and traditional rivets. Traditional rivets often have a more visible head on both sides of the joint. While this might be acceptable or even desirable in some industrial or rustic applications, in others, it can be a drawback. For example, in high - end furniture or architectural applications, the exposed rivet heads might not look very appealing.
Closed blind rivets, on the other hand, offer a cleaner look. Once installed, the only visible part is the smooth end of the rivet on the accessible side. This makes them a better choice for applications where appearance matters, such as in consumer electronics or automotive interiors.
Versatility
Closed blind rivets are incredibly versatile. They can be used with a wide range of materials, including metals, plastics, and composites. They come in different sizes and materials, such as aluminum, steel, and stainless steel, to suit various applications. The Lantern Type Blind Rivet, for example, is great for applications where you need a larger bearing surface or a more flexible connection.
Traditional rivets are also versatile, but they're more limited in terms of where they can be used due to the double - sided access requirement. They're commonly used in heavy - duty applications like bridge construction and shipbuilding, but their use in more complex or hard - to - reach areas is restricted.
Conclusion
So, to sum it up, closed blind rivets and traditional rivets each have their own strengths and weaknesses. Traditional rivets are reliable, cost - effective, and have a long - standing reputation in heavy - duty applications. But they can be a hassle to install in some situations.
Closed blind rivets, on the other hand, offer the advantages of one - sided installation, high strength, good corrosion resistance, better aesthetics, and greater versatility. While they might be a bit more expensive upfront, the time and labor savings, as well as the performance benefits, can make them a smart choice for many projects.
