Using Loctite in deep sea environment with 316 fasteners? 1

[adamgnt]

Hi all,

I am having some trouble with 316SS 10-24 FH screws backing out of their 316SS housing during system deployment. Looking to implement some sort of thread locking, but unsure of Loctite's performance in an open marine environment, and also if it arises any corrosion concerns (he housing are zinced). I know there are many types offered, I'm spending the morning looking through Loctite's site, all feedback of appropriate #'d product lines is welcome.

Thanks,
--Adam

Well, any Loctie product is going to beat the hell out of nothing, but you can get a real expert recommendation just by calling them.

Thanks for the reply Mike, I did put an e-mail out to there customer service but no answer as of yet. I'm take your wording as saying any Loctite product won't make a difference beyond what the general conditions would dictate? I threw my question up on here on the chance that someone may say "Yeah, I use 242 all the time on my underwater fasteners and no problems."

Thanks again,

With a stainless fastener into a stainless housing I would expect the galling to do a good job of preventing the screw from backing out.

At any rate, once cured most grades of Loctite relatively impervious to sea water. There are differences amongst the grades, so check the TDS or talk to one of their application advisers, then check the TDS.

Use one of the primers on stainless.

I heard back from the Loctite representative and he confirmed that there were no extraneous issues involved with corrosion. I'm going to use the medium strength (blue) primer-less 243 for this application. Thanks to Mike and Mint for your replies and hopefully the thread will help someone else with the same question in the future.

Cheers!
