Will stand by: Be SURE to use the correct size drill bit for the rivnut you use, from the same manufacturer.

I agree it depends on the brand/type of rivnut/nutsert... never questioned verifying the hole size, always confirm that.
Some sources say 3/8 rivnuts use a 9/16 hole, some say 17/32 yet some say its a range of size depending on how tight you want the nutsert in the hole and that its best to measure the OD of the rivnut to determine size as they can vary.
When I asked the guy behind the counter at fastenal what size drill bit for the rivnut I bought, he blurted out 9/16 without hesitation, but the fastenal link does say 17/32. If it does require a 17/32 drill bit, general purpose ones are like $5-6 and easy to find at common home stores or hardware stores so thats not really a big deal.
