Hey there! As a supplier of open core rivets, I often get asked about the available sizes of these handy fasteners. So, I thought I'd put together a blog post to give you the lowdown on all the different sizes we've got on offer.
Open core rivets are super versatile. They're used in a whole bunch of industries, from automotive to aerospace, and even in DIY projects at home. They're great because they can be installed from one side of the material, which is really useful when you don't have access to the back.


Let's start with the basics. The size of an open core rivet is usually described by two main measurements: the diameter of the rivet body and the length of the rivet.
Diameter Sizes
The diameter of open core rivets can vary quite a bit. We typically offer diameters ranging from 1/16 inch all the way up to 3/8 inch. The smaller diameters, like 1/16 inch and 1/8 inch, are perfect for lightweight applications. For example, if you're working on a small electronic device or a piece of jewelry, these tiny rivets will do the job just fine. They're not too strong, but they're great for holding together thin materials without causing any damage.
Moving up a bit, 3/16 inch and 1/4 inch diameter rivets are more commonly used in general manufacturing. They can handle a bit more stress and are suitable for joining medium - thickness materials. You might find them in furniture construction, where they're used to attach metal brackets to wooden frames.
The larger diameters, such as 5/16 inch and 3/8 inch, are for heavy - duty applications. These rivets are incredibly strong and can withstand a lot of force. They're often used in the construction of bridges, large machinery, and even in some military equipment.
Length Sizes
The length of an open core rivet is equally important. It needs to be long enough to go through the materials you're joining and form a proper head on the other side. We offer lengths starting from 1/8 inch and going up to 1 - 1/2 inches.
Shorter lengths, like 1/8 inch and 3/16 inch, are used for very thin materials. If you're only joining two thin sheets of metal or plastic, these short rivets will work well. They're quick and easy to install, and they don't add much bulk to the joint.
Medium lengths, from 1/4 inch to 3/4 inch, are the most commonly used. They're suitable for a wide range of applications, from automotive bodywork to household appliances. You can use them to join multiple layers of different materials, as long as the combined thickness doesn't exceed the recommended capacity of the rivet.
Longer lengths, 1 inch and above, are for thick materials or when you need to create a very strong joint. For example, in shipbuilding, long rivets are used to join thick steel plates together.
Special Sizes and Custom Orders
In addition to the standard sizes, we also offer some special sizes. For instance, we have metric - sized open core rivets for customers who prefer the metric system. These come in diameters like 2mm, 3mm, 4mm, and 5mm, with corresponding lengths.
And if you can't find the size you need in our standard catalog, don't worry! We're more than happy to take custom orders. Just tell us the diameter and length you require, and we'll do our best to manufacture the rivets for you.
Now, let's talk a bit about the different types of open core rivets. You might also be interested in Open Type Blind Rivet. These are similar to open core rivets but have a slightly different design. They're often used in applications where you need a more secure and tight joint.
Another type is the Lantern Blind Rivet. These rivets have a unique shape that allows them to expand in a lantern - like fashion when installed. They're great for applications where you need to fill a larger hole or join materials with uneven surfaces.
And if you're looking for something even more robust, check out Closed Core Rivet. These rivets are sealed at the end, which makes them resistant to water, dust, and other contaminants. They're commonly used in outdoor and marine applications.
If you're in the market for open core rivets, we've got you covered. With our wide range of sizes and the ability to take custom orders, we can meet all your riveting needs. Whether you're a small DIY enthusiast or a large - scale manufacturer, we're here to provide you with high - quality rivets at competitive prices.
So, if you're interested in purchasing open core rivets, or if you have any questions about the sizes or types we offer, don't hesitate to get in touch. We're always ready to have a chat and help you find the perfect rivets for your project.
