Also the oldie-but-goodie, NASA Fastener Design Manual [1]. Rivnuts are on page 32, but not a lot of space is spent on them - they aren't strong enough for your rockets and satellites, although the military is willing to consider other types of blind rivets (page 94). Rivnuts look great to me, though!
