Actually, if you drill a 3/16" hole in a tang and try to insert a piece of 3/16" pin stock into it you will find that the pin is too large and you'll need to ream out the hole-at least most of the time. With the rivets that I've used if they are listed as 1/4" shank then the shanks just a little undersized and will fit in a hole drilled with a 1/4" bit.

When using pin stock, first of all measure to make sure that it's not undersized, a case that I ran into once with come copper rod. You can then get a number or metric bit that is just a couple of thousandths of an inch large than the nominally sized bit of the same diameter to get a closer fit than a fractional bit 1/64" larger. I actually get the tightest fit by drilling the holes with the same size fractional bit and very carefully reaming it with a bur in my Dremel tool. Just a couple of passes around the hole and check for the fit.
