Most of the pressure of the door should be supported by the stop pads, rather than the bolts. The force on the bolts should generally be from vibrations, not from pressure differential pushing the door out.

other than pressure differential...what about the weight of the plug door itself ... do the bolts support that weight?

or if some other mechanism like the springs on hinges below grew weaker over time .. would that in turn put too much weight on the bolts?
