Advice please - fitting an extra bracelet link

[Gurmot]

Good afternoon on a beautiful sunny day here in Somerset, UK.

I have a question which I suspect is fairly straightforward. My 16520 SS Daytona is a little tight on hot days when my wrist expands but there is no adjustment left on the clasp so I need another link fitted.

Question - do I need to use Loctite or similar when fitting screw pins on a bracelet? I'm afraid that the screws may come undone at some future point if I disturb them.

If so, what type of Loctite should I get?

Thanks - Simon
