Re: Rivet Nuts
Having a small relationship with these guys back in 2010 & 2011 on my old team, I can try and give some insight.
I clearly remember that we had used hex for mounting our brackets to our frame for our arm supports. During season, they weren't really a big problem at all when it came down to failing. I never had the chance to see the chassis after the season to inspect the nuts but I can say they held up well within the 1/8" plate that they were secured in.
However, I do believe that because of the justification that the experience on my end and your end is rather low that the single best option would be to either make separate plates and tap where necessary or just tap directly into the tubing. Also, in some cases, thru bolting might not be a bad choice either.
