Buy a tube of "LIQUID NAILS" (with a screw-on top).
Unscrew your screws, dip screw ends in Liquid Nails, screw back
together.
Tidy up with nasal tissue or a bit of toilet paper.
When dry, reload shelves.
It is the easiest way to turn pressed fiberboard into tolerable solidity
on a budget.
Normal pressed fiberboard, with a bit of jostling after assembly, will
loosen up the screw holes and begin to fall apart. Ideally you will want to
soak the cheap pressed fiberboard bookshelves with polyurethane sealant or
polyurethane varnish (this will cause the cheap printed laminate to peel
off, but you should chemically improve any cheap pressed fiberboard
furniture and let air dry as the cost is and extra $10, but the payoff is
long-term durability versus the costs of higher quality hardwood furnature.
