yes, I have used riv nuts .. one case a brazed in boss came loose, so rather than repaint i drilled out for the riv-nut
my Koga, in heat treated 7005, has them for all the threaded bosses..
NB if loose they can be tightened by further expanding them in place..
also , since its a water bottle you want
Twofish Unlimited has strap ons ..
