Have used quite a few riv-nuts in my camper build. If planning to use a few getting the tool is worthwhile. The one I bought (like this) was fairly exy at $160, an air one to run off my compressor. Don't regret buying it for a moment. You do need to practice a bit with it before use though, if wrongly adjusted it can pull the threads out of the riv-nut, leaving the task of then removing the inserted riv-nut. Bugger of a job, especially in confined areas.

I bought one off Fleabay for $99 - then spent another hundy or so on the nuts in M4,6 & 8. Awesome tool, hardly anything on my truck uses self-tappers any more!

I had the hand tool before I bought the air one. M6 was hard, M8 just barely possible with much grunting & swearing. Air tool is effortless, although as cuppa said you need to drop the pressure with a reg as it will easily strip a insert or break a shaft on the smaller sizes
