Hey there! As a supplier of closed core rivets, I often get asked about the available sizes. So, I thought I'd put together this blog post to give you the lowdown on all the different sizes we've got in stock.
First off, let's talk about what closed core rivets are. They're a type of blind rivet that's great for applications where you need a strong, watertight joint. Unlike Open Core-pulling Rivet, which have an open end, closed core rivets are sealed at the end, preventing moisture and debris from getting in. And compared to Lantern Core-pulling Rivets, they offer better resistance to corrosion and leakage.
Now, onto the sizes. We offer closed core rivets in a wide range of diameters and lengths to suit different needs. The most common diameters we carry are 3mm, 4mm, 4.8mm, 5mm, and 6.4mm. These diameters are suitable for a variety of materials, from thin sheets of aluminum to thicker steel plates.
Let's start with the 3mm closed core rivets. These are the smallest size we offer and are perfect for applications where you need a lightweight, low-profile fastener. They're commonly used in electronics, jewelry making, and small-scale metalworking projects. The 3mm rivets typically come in lengths ranging from 6mm to 12mm, giving you some flexibility depending on the thickness of the materials you're joining.
Next up, the 4mm closed core rivets. These are a bit more versatile and can handle slightly thicker materials. They're often used in automotive, aerospace, and general manufacturing applications. We have 4mm rivets available in lengths from 8mm to 16mm, so you can choose the right one for your project.
The 4.8mm closed core rivets are another popular choice. They offer a good balance between strength and size and are suitable for a wide range of applications. You'll often find them in construction, furniture making, and marine industries. We stock 4.8mm rivets in lengths from 10mm to 20mm.
The 5mm closed core rivets are a bit beefier and can handle even thicker materials. They're commonly used in heavy-duty applications such as machinery, transportation, and structural steelwork. We have 5mm rivets available in lengths from 12mm to 25mm.


Finally, the 6.4mm closed core rivets are the largest size we offer. These are designed for the most demanding applications where you need maximum strength and durability. They're often used in bridge construction, large-scale machinery, and industrial equipment. We stock 6.4mm rivets in lengths from 16mm to 30mm.
In addition to these standard sizes, we can also produce custom-sized closed core rivets if you have specific requirements. Just let us know the diameter and length you need, and we'll do our best to accommodate you.
When choosing the right size of closed core rivet for your project, there are a few things to keep in mind. First, consider the thickness of the materials you're joining. You'll want to choose a rivet length that's long enough to penetrate both materials and form a secure joint, but not so long that it protrudes too much on the other side.
Second, think about the strength requirements of your application. If you need a very strong joint, you may want to choose a larger diameter rivet. However, keep in mind that larger rivets may also require more force to install.
Finally, consider the installation method. Different sizes of closed core rivets may require different types of rivet guns or installation tools. Make sure you have the right equipment on hand before you start your project.
So, there you have it! That's a breakdown of the different sizes of closed core rivets we offer. Whether you're working on a small DIY project or a large industrial application, we've got the right size of rivet for you.
