Not to get too off-topic, but as someone who had never even heard of Rivnuts before seeing this thread, I'm curious... What are the actual benefits of using a Rivnut? Most of the application examples I've seen so far look like it would have been far simpler and faster to just use a regular bolt+locknut.
Lots of applications where you cannot get to the back side to use a nut and the material is too thin to thread.
