A cheap fix would be to buy round, plastic, adhesive backed tabs from Home Depot and slap them on.
The proper fix would be to back a screw out, counter sink the hole slightly, carefully
epoxy an oak plug on the screw head (lining up the grain) and the next day carefully shave the excessive off, low side to high side, with a very sharp chisel.
I''ve done that on old teak decks and it works fairly well, but it''s labor intensive.
