I have a kit of stainless metric nuts bolts and washers....they have been invaluable in Rocket maintenance. Except for the decorative bolts like holds the instrument panel on the tank. I will eventually have all exposed fasteners replaced with stainless. The fuel tank bolts were the first for they original ones indeed vanished the first time I raised the tank!
I Use a painted steel hex bolt now...ive lost 2 stainless bolts on 2 seperate ocasions in this location never to be found again. I took Mr Charles Darwin's advice and evolved by using a magnetized long reach hex on a 3/8 socket head and keeping the bolt magnetic steel
