let me SKL first, I am assuming you want to use Loctite to secure your bracelet link screw and most probably a Rolex bracelet.
truth is, you can use UHU glue, cheap and reliable.
just use a very little tiny bit on the screw and it is good enough to secure the screw and easy enough to loosen up with the soaking of warm water.
yes, i know the name UHU sounds cheap but you can get it everywhere.
Loctite 222 you need to order thru eBay
