If the head of that philips screw is interfering with something,perhaps
file the head of the screw down and hacksaw a slot in the head of the
screw so a flat blade screwdriver can be used to tighten the screw back
down.I have worked on screws a lot of times before with hacksaws and
files.And hammers and chisels and cussin them damn screws and bolts out
