Extra securing methods for rivetnuts?


Recommended Posts

When installing rivet nuts into the doors sheetmetal with a rivet gun/tool, is there some extra things ya'll do to make sure the rivet doesnt start spinning in place when torquing down a bolt/screw. For example some kind of loc-tite or JBweld type of thing? Some of my rivets end up coming loose and spinning in place when i try to torque down on it. 

What have you guys used that works well for "overkill" on a rivetnut. 

Clue to whats coming to the Chargers build log tonight.

Shit was expensive for just one sheet. Couldve got 3 sheets of different thicknesses for the same price, but shipping on those three was more then the three sheets lol smh. 400 for plastic, 500 for shipping. Instead i opted to pay 400 locally for one sheet and pick it up myself. Not sure whats the better deal just know i was fkd either way lol. Went for the quicker one.

I would think if the proper sized hole is drilled and the nut is installed correctly there should be no need for to add anything to keep the fastener in place.

Maybe a poor quality nut and or installation tool or even user error (no offense) might be the cause.

As for a solution to keep them from spinning, maybe some of that thick CA glue you can get from mobile solutions used on the backside of the metal panel and outside of the nut might work?

Is that plastic UHMW? Why not just go with some PVC or something like that?

Aluminum, steel, or stainless steel rivnuts?

I would personally use stainless steel rivnuts exposed to places where water will be present.

You might not be compressing the nut enough to get a good seal to the metal.

Did you try putting the press tool back on the rivnut and re-pressing it?  Ive done that before.

Do your rivnuts have serrations on the side that touches the metal?

Not sure whats causing the spinning, maybe it was just slightly too big of a drilled hole. The tool i got should be legit, its not a "harbor freight". 

Would CA glue work on metal to metal??? I have a set of different mobile solutions CA glues, the thin, thick and gel with activator. 

Is HDPE high-density polyethelene its made for marine purposes mostly. I go with this or abs to avoid the extra toxicity of using other cheap plastic like pvc and stuff. All the butly smells bad enough lol and its very rigid. And cuts well.

I didnt try that, thanks for the idea, ill try it out. Yah it has those ridges that are supposed to help bite into the metal.

Have you tried it out already? How did it go?

I drilled the lose ones out and reinstalled a new one into the same hole with some CA glue between the sheet metal and rivetnut. It held fine now. I was able to tighten it enough to be secure. But i didnt try to really torgue it down, just tight enough to secure it.

I would almost use an epoxy over CA glue. CA can be strong, but it can also be very brittle depending on what type your using, and how much accelerator is used.
I would possibly try getting epoxy between the rivet and panel that your installing the rivet to before compressing it.
