Response to Check for the o-ring
Loctite is an option, but use the low strength (purple) variety. It's a little harder to find than blue or red. If you have a watchmaker's supply near you it doesn't hurt to pick up a movement oiler. This is a small applicator that will help you to get a small amount of loctite onto the screw or screw hole.
