I've spent way too many hours struggling with traditional buckles when a simple magnetic snap rivet could have saved me a ton of hassle. If you've ever tried to close a heavy leather bag while holding a coffee and a phone, you know exactly what I'm talking about. There is something incredibly satisfying about that tactile "click" when the magnets find each other and pull your bag shut without you even looking.
It's one of those small hardware pieces that you don't really think about until you use a bag that doesn't have one. Suddenly, you're fumbling with straps or noisy Velcro, and you realize how much better a smooth, silent magnetic closure really is. But choosing the right one and actually getting it installed properly is where things can get a little tricky if you're new to the world of bag-making or leathercraft.
Why These Snaps Are Better Than the Rest
When you're looking at closures, you usually have a few options: buttons, zippers, buckles, or standard pronged snaps. The magnetic snap rivet stands out because it combines the strength of a permanent fastener with the ease of a magnet. Unlike the prong-style snaps that you often see on cheaper store-bought bags—which can sometimes bend or tear through thin fabric—the rivet version is much more heavy-duty.
The "rivet" part of the name is the key here. Instead of having those little metal legs that you fold over a washer, these use a post and a cap, just like a traditional leather rivet. This means they're much harder to pull out. If you're working with thick leather or heavy canvas, a rivet-style snap is almost always the way to go. It looks cleaner on the back, and it feels a lot more professional when you're handing a finished project to a friend or a customer.
Picking the Right Size and Strength
Not all magnets are created equal. If you pick a magnetic snap rivet that's too weak, your bag is going to pop open the second you put anything more than a wallet in it. If it's too strong, you'll feel like you're in a tug-of-war every time you want to get your keys out.
Most of the ones you'll find come in two standard sizes: 14mm and 18mm. The 14mm ones are perfect for smaller clutches, wallets, or even the inside pockets of a larger tote. They're subtle and don't add much weight. The 18mm versions are the workhorses. These are what you want for a main flap on a messenger bag or a backpack. They have enough "pull" to keep a heavy flap secure even if the bag is a bit overstuffed.
You also have to think about the finish. Most makers go for antique brass or nickel because they match almost everything, but don't sleep on gunmetal or rose gold if you want a more modern look. Just make sure the finish on your snap matches the rest of your hardware—nothing ruins the vibe of a handmade bag faster than mismatched metals.
The Installation Process (Don't Stress It)
I know, punching holes in a project you've spent ten hours on is terrifying. I still get a little nervous every time I pick up the hole punch. But installing a magnetic snap rivet is actually one of the easier parts of the build once you get the hang of it.
First, you've got to mark your spots. I usually suggest marking the "male" side (the part with the little bump) on your flap first. Once that's in place, you can fold the flap down, press it against the body of the bag, and see exactly where the "female" side (the part with the hole) needs to sit.
Punching the Holes
You'll need a hole punch that matches the diameter of the rivet post. Usually, a 2mm or 3mm punch does the trick. Make sure your leather is resting on a sturdy scrap piece of wood or a poly cutting board so you get a clean cut. If the hole is too small, you'll struggle to get the post through and might distort the metal. If it's too big, the snap might shift around over time.
Setting the Rivet
Once your holes are punched, you just slide the post through the material and pop the cap on the other side. Now, here's the important part: you really need a proper setter. You can technically use a flat hammer, but you risk scuffing the finish or, worse, flattening the "bump" on the magnet so it doesn't click into place anymore. A concave rivet setter or a hand press makes this foolproof. It cups the snap and applies even pressure so everything stays pretty and functional.
Common Mistakes to Watch Out For
We've all been there—you finish a bag, go to snap it shut, and realize something is off. The most common issue I see is people forgetting to use a "reinforcement" layer. If you're installing a magnetic snap rivet on a thin leather or a light fabric, the magnet might actually be stronger than the material itself. Over time, as you pull the snap open, the metal will eventually tear right through the fabric.
To fix this, I always glue a small scrap of stiff leather or heavy interfacing behind the hole before I set the rivet. It spreads the tension across a larger area and keeps your bag from falling apart after a few months of use.
Another thing to keep in mind is the "thickness" of your material. Rivet posts come in different lengths. If your leather is too thick, the post won't reach the cap. If it's too thin, the snap will be loose and jingle around. If you find your leather is too thin for the rivet you bought, just add another leather washer on the inside to take up that extra space.
Where to Use Them (Get Creative!)
While bags are the obvious choice, a magnetic snap rivet can be used for all sorts of stuff. I've seen them used on: * Journal Covers: Keeps your notes from flopping around in your bag. * Tool Rolls: Much faster than tying a leather cord. * Phone Cases: Provides a secure closure that doesn't mess with the screen. * Coat Closures: A cool, modern alternative to traditional buttons.
I even used a couple of these for a custom camera strap once. I wanted a way to quickly tuck away a lens cap, so I put a small magnet on the strap and a thin metal washer on the cap. It worked like a charm. Once you have a few of these in your toolbox, you start seeing places for them everywhere.
Final Thoughts on Magnetic Hardware
At the end of the day, using a magnetic snap rivet is about making things easier for the person who's going to use the item. It's that little bit of extra "polish" that separates a hobbyist project from something that looks like it came out of a high-end boutique.
They're affordable, they're tough as nails, and they give your work a functional edge that people really appreciate. Just remember to measure twice, punch once, and maybe use a little bit of loctite or glue on the threads if you're using the screw-in type of rivet snaps. There's nothing quite like the confidence of a solid "snap" to tell you your project is officially finished. Now, go grab a pack and start upgrading your gear—you'll wonder why you ever bothered with those old-school buckles in the first place.
