So I replaced my loose ones with pop-rivets. Maybe not appropriate for your problem though. Liquid nails sounds fine too me.

Usually it is the other way around: In unstable and flimsy material one uses coarse thread screws for better hold. Look at the so called "dry wall" screws. They are all coarse thread.
