Just thought I'd update for anyone who may be looking or searching in the future. I had previously called Harbor Freight to see if they had rivnuts or rivet nuts. They said they didn't carry them. I poked around on the site today and found "threaded rivet inserts"(says rivnuts on the instructions/back of the package) and installation tool. The package with ~8 of four different size rivnuts and the tool was under $20.
