I have a couple of shaved rivets. These are trifold exploding rivets.
I'm going to insert the rivet. I have my rivet tool. You don't install these like a
normal rivet, you don't keep cranking the rivet tool until it snaps, but you do
want to snug it up to the backside. I'm going to show you...
As you can see here: that's the correctly installed, that's correctly installed, and that is
incorrectly installed. You can see that it's not totally up against the backside.
So you want to make sure that you install the rivet properly so you have a
nice tight fit. And then I'm going to take my snips...
I'm gonna leave about half an inch. I'm gonna snip these off- that's a little bit more than a half an inch...
Now I'm going to take my shaver. With these shavers you have to select the correct
bit along with the correct crown to shave off this mandrel properly.
It's a little tricky, so you have to learn as you go.
You just gotta go a little bit at a time. You can't just push down on it hard.
That's it right there.
Look at that. Very nicely finished. Nice looking product.
That's your backside and that's your trifold.
I have a hole that's larger by 1/16" then what this should be. It should be a 1/4" hole.
So the hole is larger. I have a backup washer here...
...and I have an exploding tri-fold rivet. I'm going to slide the rivet in,
and then take the washer and I'm gonna put this washer on the back. I'm gonna swing this around so you can see it.
So there you go. You can see that it's larger than the hole.
I put a backup washer on the back of the material.
You have to have access to the back and in a lot of situations you don't.
If you want to be firm and structurally sound when you install the rivet,
you're gonna need this backup washer.
I think with these rivets it should work pretty good.
I have a very large tool here for this type of rivet.
Let me tighten this down...
Again, make sure this rivet washer is right up against the back of the steel.
We're going to start to crimp.
It's beautiful. So let me just turn this around so you can get a better look.
You can see how nice that fastened in an oversized hole. It does not move around, it's solid.
You need to include the thickness of the rivet washer in your calculations.
So you can see the circumference of the washer, how much
more you get. You get about an eighth of an inch I would say, approximately,
depending on the washer.
This is a #6 washer along with a #6 pop rivet.
So this will show you exactly how it's installed and where it goes.
So you don't take a rivet washer and put it on the front here; it just doesn't work.
The other thing I wanted to show you was that a wide flange has a wider circumference.
So now I'm going to install the rivet with the rivet washer attached.
...into the tool. Now I have my rivet washer on here...
I'm also gonna install right now a wide flange, and that would be without a rivet washer attached.
So this is the large flange with no rivet washer and this one is the standard rivet with the washer attached.
This is the back.
That's basically the demonstration of a rivet washer being installed.
So I have here a well nut. They fall under the category of rivet nuts.
This is an EPDM neoprene nut and inside it has a brass threaded insert.
So this works well in many different applications, and we'll go through those applications.
So I'll use this as my material that I'm attaching.
Now you can attach multiple materials together with this nut.
I have here a 1/4"-20 pan head machine screw with a washer on top.
If you're going through, let's say a motorcycle windshield, and you want to fasten it to a bracket to hold it on,
which is a great application for this,
you would push it through and then you would put the screw in and then you would start to tighten the screw.
You don't have to use this for your application, it depends on your application, but I'm using this impact just for demonstration.
As you can see, it's tightening up there.
That's the back of the well nut.
You wouldn't necessarily have to use this long of a screw, you can use a shorter screw.
This is just a demonstration to give you an idea what this looks like. that was the back and
That was the back and this is the front.
So if you were installing glass or plexiglass, this is perfect.
If you wanted to install something on your boat, fish-finders or something of that nature,
you can use this type of application.
So well nuts can be used in many different applications. They're great for shock and vibration.
Pull-through is an issue. It's not the best for that.
If you use this in a saltwater environment you're gonna have to change them every-
I don't know how many-years, depends on how it holds up, but the EPDM will also deteriorate over time
in a saltwater environment. I just want to bring that to your attention.
But, you know, they're great for vibration applications: motorcycles, windshields, many, many, things.
