I used a bolt and some fender washers, and my torque wrench. I pulled a couple of them on a scrap of aluminum to determine the right amount of torque. They look and didn't come lose, so it works. Your results may vary, of course.

The advantage to the more expensive tool is that you can put in the rivnuts faster, not a consideration unless you are putting in 100 at a time. Do stay away from the cheap combination rivnut/pop rivet tool that Harbor freight sells. It might be O.K. for the larger sizes, but I broke two of the 6-32 mandrels because they are not very good steel. The mandrel you can buy from Spruce and Wicks to go in a standard pop rivet tool is better steel and works O.K. A regular pop rivet gun has enough pull, but it is not as easy to control the exact pull like the economy tool that uses a wrench. I do recommend using the keyed rivnuts.

Rivnuts are handy where you are working something with a blind side, such as if you need a threaded attachment to a tube and you can't access the other side to install a nutplate or nut. The "real" rivnut tool isn't cheap and neither is the "simplified" model, but there is a mandrel available such that you can install them using your regular pop rivet puller. My question is, does a regular pop rivet puller have enough backbone to pull a rivnut? If so, who would buy the $100+ tool in the first place? And it seems like it would be easy to strip out the threads if you put too much squeeze on it, but again- I've never installed one so I guess you just squeeze a little at a time. I don't have a lot of them to install, so I don't need a heavy-duty tool for the job.

They take expensive special tools to insert correctly, but they do work great when done right. Regular aircraft Rivnuts are a lot more tollerant.

My question is, does a regular pop rivet puller > have enough backbone to pull a rivnut? Sound like Serge's tool will work fine, given his experience, but you do need to be careful. The project I just finished up (at work) required several hundred knurled rivnuts (which are less likely to spin), so we learned a lot about them in the fabrication process. Maybe Serge and I are talking two completely different kinds, so I can only speak to the ones we used, which came from McMaster Carr. We cheaped out and bought the "simplified model" ($170 or so), but I don't see a lot of difference between that and the $250 model. The problem with that is if you don't get it tight enough, the rivnut just spins, and you can't tighten up the bolt. If you squeeze it too tight, the threads get scrunched up and distort, and the bolt binds and the rivnut spins. You'd think after several hundred, you could get the feel of it, or get it adjusted correctly, but it never happened. Keep in mind that these guys are not just "Bubbas", they're well-trained experts who commonly fabricate space, defense, and nuclear hardware day-to-day. We eventually drilled every one of them out and welded custom made aluminum inserts into those holes, and have had no problems since. These were relatively large rivnuts (3/16", 1/4" and 3/8"), so it may be that the smaller stuff that we'd use on airplanes isn't as touchy, but I personally have deleted them from my fastening options list, next time I have something in a blind hole that needs threads. Some of these rivnuts were $4-5 each, but the bosses we welded in were made overnight for about thirty cents each on our CNC lathe, and were welded in place about as fast as you could use the rivnut installation tool, but that's not an option for most homebuilders...

It depends on the size of rivnut and the thickness of the aluminum. Fiberglass or non-countersunk rivets would definitely need the notch filed. On one of my KRs I had rivnuts in the fiberglass cowling. They were epoxied in and were not the keyed rivnuts. I had a couple spin on me and it was nearly impossible to get the cowl off and replace the rivnut. Be extra sure if you put them in fiberglass that you rough them up good and put some flox on them after they are installed, especially if they are somewhere that you can't get to them if they spin.
