Weld nuts are by far the best because they are welded in place. Pems are great if you have a press to install them. Rivnuts are good depending on where you are going to use them, but I have experienced them pulling loose.

The general problem with all of the above solutions is their inability to be fixed on the fly. A bolt and nut, bolting all the way through a tube is by far the best solution. Just make sure that you provide something to avoid crushing the tube. I prefer wooden blocks inserted into the ends, but there are also bushing that can help to support this.
