Rivnuts question
I am replacing lower rad support/front impact skid plate, and requires 3 rivnuts to attach the air dam, my question is, how does one get the rivnuts to expand in the hole ? Obviously it is a blind hex hole and no way to hold it, unless, the rivnut is a snug fit in the hole and screw a bolt into it and hopefully it expands from there ? I have never used them before and they ain't cheap, so i don't wanna mess it up.

The make a tool that looks like a rivet gun or you can take a bolt and nut along with a washer. Put the nut on the bolt, the the washer, screw it into the rivnut and then turn the but and hold the bolt and it will pull it up and seat it.
This shows with or without a tool.

so what you are saying on the 2 nd one, just screw the screw in to the bottom and it will expand itself and the hex hole will hold it from turning ?
if that is the case, thank you very much.

You need a bolt that fits the rivnut and a regular nut and washer that fits the bolt. Screw the nut on the bolt and install the washer. leave enough thread to screw the bolt into the rivnut. Then hold the bolt so it can't turn and turn the nut so the nut and washer presses against the front of the rivnut. Keep turning the nut until the rivnut collapses enough to be tight in the hole. Harbor freight also has a tool for about $20 that works well.

from the 1st video, looks like the bolt has to be long enough to thread all the way through, instead of just a few threads ?
thank you.

It doesn't have to but the farther the better because it's the center that crushes so you need the threads to grab pretty deep.

The exchange rate is killing you up there. Don't know if you do business with Performance Improvement or Johnson Research, but the price of our oil is selling for 50% more than in the US.

I was poor with two kids, so I didn't buy the tool either!

I had to use them to install my front tow hook also and from that experience I can say, "I hate rivnuts!" LOL! Yeah took some time, especially while lying on my back, but finally got them seated. I watched all the videos that I could on YouTube, and I thought it was a simple process, but still took forever and even had me saying "How'd I get them to seat?" By the time I was done. Just glad I finally did it. LOL!

[QUOTE=05 Wreck;1591292522]Not sure if I will ever need to use the rivnuts again, but if I do, I think it may be good to have the install tool. Doing it without, kind of just seemed hit and miss. I had to try it several times before it finally took. For such a small job, it seemed kind of frustrating.
