I've got an Aria guitar similar to an es-175. Closest to the neck, the mount screw goes direct into the maple laminated body. A humbucker screw was holding it. After some recent work where I took the pickguard off, the screw wouldn't hold. Should I just get a bigger screw? Current screw was a #3, but the #4 screw like a strat pickup screw that I tried is too big. Maybe something like a #3 wood screw? Can I use glue in some way to fill in the hole?
