The bolt head is not spring loaded, the wave washer is very weak and is only there so they can get away with tolerances. If they throw in a wave washer they don't need to carefully machine that end of the bolt body which would be much more expensive and time consuming than a cheap washer. I switch the position of the wave washer and place it between the bolt head and the baffle to help keep grease on the lugs.Gas baffle in case of a ruptured case. What forces the bolt open is the spring-loaded bolthead.
