Tool for screw link and Loctite

[Longhorn02]

What kind of tool does one use to tighten the screw when you add/remove the link and which kind of Loctite is used?

The AD adjusted a link on my bracelet, but now the link joint is stiff and doesn't bend freely. When I do move the links, I can see the screw flathead area move with the movement of the joint (not by much but I can imagine over time the screw getting looser to the point of coming out).



I'm thinking I need to adjust it myself to make it more free moving but also want to make sure it doesn't come undone so I'd like to ensure it has a fresh amount of Loctite.

Anyone had a similar issue?
