Vibration and movement are always present on a boat at sea and can easily loosen screws. To avert the substantial problems that even a single backed-out screw can cause, we use Loctite thread lock fluid. Use Blue if you want to undo it easily, Red if you want to work at it and Green if you want to have to use explosives.
Phyllis has sailed over 40,000 offshore miles with John on their McCurdy & Rhodes 56, Morgan's Cloud, most of it in the high latitudes, and has crossed the Atlantic three times. As a woman who came to sailing as an adult, she brings a fresh perspective to cruising, which has helped her communicate what they do in an approachable way, first in yachting magazines and, for the last 18 years, as co-editor/publisher of AAC.
I guess you use the Loctite in conjunction with TefGel? If so before or after?
No we use Loctite or TefGel, depending on the application. They are not compatible.
Can you give me a maker’s number for the red Loctite you recommend?
Have you found the Loctite has the same anti corrosion properties of TefGel?
We use red Loctite #222 for things we do not ever want to remove and blue #243 for things we might want to undo. And no, the anti-corrosion is not on a par with TefGel. But if you want to be sure that a screw that is subject to vibration won’t come out, Loctite is the solution.
