I am not a gunsmith & I do not play one on TV, but you are going to need a little tap, tap with a small mallet & correct, fitted turnscrew, possibly with a piece of leather with a small hole in it to protect the plate. Sears used to sell a hammer/screwdriver that when you hit it on top with a hammer, the screw-driver would turn. Anyway, you just need a little force to break the friction.
