When I first started working on my DIY projects, I remember being utterly confused by the array of fasteners available at the hardware store. Among the bewildering options were pop rivets and tubular rivets. To the uninitiated, they might seem similar, but they serve distinct purposes in construction and manufacturing. Understanding the key differences between them can save time, frustration, and even money.
Pop rivets, often known as blind rivets, gained fame during World War II when they revolutionized aircraft manufacturing. They allowed workers to fasten parts from one side, which was a game-changer in terms of efficiency. Imagine trying to assemble two aluminum sheets when access to the other side is obstructed by another component or wall. This is where pop rivets shine. Their unique design includes a mandrel that, when pulled, bulges the rivet body, locking it in place. The speed at which they can be installed—over 30 rivets per minute by a skilled worker—makes them incredibly efficient for assembly lines.
On the other hand, tubular rivets require access to both sides of the workpiece. Commonly found in items like leather belts, book bindings, and sometimes in decorative items, they have a hollow body that is flared using a specialty tool. Unlike pop rivets, tubular rivets offer more of a permanent fastening solution in applications where aesthetics matter, thanks to their clean finish. Pop rivets may leave a mandrel tip protruding, which isn’t always ideal if a smooth surface is required.
Digging deeper, tubular rivets tend to be more versatile in terms of the materials they can handle. They’re excellent for fastenings on softer materials, which might get damaged by the force of installing a pop rivet. Tubular rivets are available in sizes ranging from tiny 1/16-inch diameter options for delicate projects, to larger 3/16-inch ones for sturdier applications. Conversely, pop rivets are typically more limited, usually ranging from 1/8-inch to 1/4-inch diameters, but they can be crafted from stronger materials like stainless steel and aluminum when shear strength is crucial.
Many professionals prefer pop rivets for projects involving metals or applications requiring some structural integrity, like trailers and outdoor furniture, which face constant stress and pressure. Considering the material, tubular rivets are more forgiving because they deform under less pressure, making them suitable for leather and plastics.
One notable advantage of pop rivets is their relatively simple installation process. A user only needs a rivet gun, which comes in both manual and automatic varieties. The manual ones cost around $20 to $40. Meanwhile, the automatic versions can cost more than $100, but they offer superior ease, especially when installing hundreds of rivets. Conversely, installing tubular rivets generally needs a rivet setter or a machine, depending on the scale of the project. These tools may range from $30 for a basic hand tool to over $500 for more advanced machinery.
Reflecting on industry standards, certain manufacturers specialize in one type of rivet over another. For example, aerospace companies might lean toward using pop rivets due to their history of reliability and ease in assembly lines. Think of Boeing, whose airplanes are meticulously assembled using fasteners designed for quick installation and high strength. In contrast, a high-end leather goods company might invest more in tubular rivets that emphasize appearance and functionality over speed.
Sometimes, the choice boils down to aesthetics and practicality. Pop rivets, because of the mandrel break-off, might not provide a smooth surface finish—an important consideration if visibility matters. Tubular rivets provide a more uniform look, making them ideal for products like handbags, where style matters almost as much as function. That said, it’s also worth noting that tubular rivets can be awkward to use in confined spaces or when the back of the workpiece is inaccessible, which could rule them out for some applications.
Both pop rivets and tubular rivets have their niche in the toolkit of any dedicated DIY enthusiast or professional fabricator. Knowing when and where to use each type can make all the difference. In the pallet of construction and DIY projects, selecting the right rivet is essential to achieving both resilience and aesthetics in your finished piece. If you’re uncertain which type of rivet to choose for your project, consider the accessibility of the workpiece, the materials in use, and whether the appearance of the fastening needs to be concealed or can remain visible.

Remember, the goal in any fastening scenario is stability without compromising on the style or integrity of your project. Each type has its merits and drawbacks, so awareness and understanding of these differences enable more informed decisions, ultimately leading to seamless and successful project completion.
