I've only used rivet nuts a few times (I find myself using them more now) and have always got mixed information about what drill bit to use with what rivet nut. Even doing a simple google search gives a lot of different info. For example, a chart I found shows to use a 1/2" drill bit for a 5/16" riv nut. So I did as practice run on some scrap and it felt super sloppy, almost like it was going to pull through. I did another with a 29/64" drill bit and it worked just about perfect. Does anyone have a trusted chart that you use for reference?
