OK, I have no experience in camera building, so take this for what it is worth. (Nothing!)
But I have experience with epoxy and fasteners.
If you put epoxy in a hole, the screw be much harder to pull out. Also, you could still unscrew it later. (Maybe you need to heat the screw a bit with a soldering gun but probably not...) This applies to both wood screws and machine screws. If you drill an oversize hole and fill it with epoxy/silica, it will be even stronger.
I suppose this isn't really needed. But might be a good idea, for example with the tripod attachment.
