Do Heli-Coils Perform Well In Saltwater Atmosphere? I'm thinking about heli-coiling some damaged bolt holes that will be exposed, but I'm wondering if corrosion will start there. Any ideas?

I have used a lot of Heli-Coils in my times, but honestly I don’t know or remember what material they are made from. If they are made from stainless steel then that would help. But corrosion can and will pop up at any opportune place, especially with salt water. And dissimilar metals are prone to that also... I’d say install them as you need them and coat them with some type paint or corrosion preventing application and watch them along the way during general maintenance...

thats what I was thinking, and since the threads will not be visible after assembly, the only way I'll be able to tell will be to dissassemble, and I hope to never dissassemble it again! Thats how the bolts got screwed up to begin with! But Thanks for the reply. Any other thoughts about this floating around out there?
