I personally am not a big fan of locktite. My experience getting screws out of links with it have been lets say very challenging. One good trick is to place the link or bracelet in hot water for a minute or two you will be surprised how much easier it will be to remove the screw. Next invest in some good screw drivers I like the Bergeon 6899-A10 great set. You need the right tool to do the job. Good luck
