I came across this when the control plate of my jazz bass was loose because of stripped screw holes. I didn't want to use any glue so I was looking for something less permanent. I know theres probably several solutions out there but I thought I'd just give you guys another option thats less destructive. I found that coffee stirrers, those little thin plastic straws, fit perfectly in the screw holes. After finding the depth of the holes I simply cut the straw, insert it back in, positioned the control plate and then tightened the screws down. Hope this is useful info for you.
