Welcome back to Albany County Fasteners - Fasteners 101
I'm Bob and today I'm going to show you how to remove a rivet and install a rivet in an over-sized hole.
Alright, I have a couple of rivets here that are installed in this piece of steel.
I'm gonna remove one right now with an oversize bit.
We're getting questions from customers asking us "how do I replace that rivet and I drilled the hole too big"?
Okay, so I'm gonna show you how to do this. There are only a couple of, well, one type of rivet that you can use
for this application which would be a exploding or trifold rivet.
With that rivet you're gonna have to use a backup washer in the oversize hole.
So let me show you how to do this. First I'm going to remove the rivet.
So now, I've removed the rivet. I have a hole that's larger by 1/16" then what this
should be it should be a quarter-inch hole, so the hole is larger.
I have a backup washer here and I have an exploding tri-fold rivet
and I'm going to slide the rivet in and I'm going to take the washer
and I'm going to put this washer on the back. I'm gonna swing this around so you can see it.
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. In a lot of situations you don't. You may be able to also use it but
if you want to be firm and structurally sound when you install the rivet you're
gonna need this backup washer. I'll also demonstrate removing the rivet and
reinstalling the rivet in an over-sized hole - without the backup washer.
I think with these rivets it should work pretty good I have a very large tool here for
this type rivet. Let me tighten this down.
I'm gonna make sure this rivet is right up against the back of the steel and we're gonna 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 over-sized hole it does not move around.
It's solid. Now I'm going to demonstrate removing a rivet and just reinstalling it.
So I removed the rivet. I over-sized the hole to 9/16".
I have another rivet and again it's over-sized.
I'm going to move this around for you to see. I'm gonna start crimping it.
Well there is a substantial difference
So you can see here that this is the rivet with the backup washer.
You can see how much better that is fastened. The one that I did in the over-sized hole,
without the backup washer you can see how it got sucked into the hole.
I would question that over time. If you're using this on a trailer where you drilled an over-sized hole to
get the other one out; the old rivet. That could tend to become
an issue. So in this situation: we have an over-sized hole, use a backup washer in a collapsing type rivet.
Thanks for watching.
