Fasteners for bronze hardware?
 
When repainting my deck I removed all of my deck hardware and some of the bolts, in particular those for the mainsheet traveller track, were rusted and broke off. I obviously have to replace those that broke and am considering replacing all of them, but am not sure what sort of metal would be best to use so as to avoid both corrosion due to dissimilar metals and to be adequately strong. The bolts that I removed looked to be something like bronze or brass, but I have only found the latter in hardware stores so far and am somewhat concerned about its softness/strength, plus I'm not sure how brass works when in contact with bronze for long periods of time in a wet enviornment.

I was thinking maybe a layer of sealant would retard any corrosion process between the metals...

So any thoughts on what would be best to use? Stainless, brass? Something else?

BTW this is for a 1968 Kittiwake 23 that is being sailed on a fresh water lake.

Thanks,

Bronze hardware needs bronze fasteners.

Not sure if Hardware is Stainless or not If it is. Stainless steel won't rest. Bed all hardware with polysulfide sealant. Polyurethane sealant's are permanant fot the most part. So think carefully about that. If you need to bed any Lexan or Plexiglass use a silicon product not a polysulfide. Boat Maintance by William M. Burr Jr. International Marine will get you through most any project. Peace happy sailing. If Bronze use Bronze.

Thanks for the link. I had been having trouble finding bronze bolts locally and on the marine supply sites.

Whatever you use, dose the fasteners with Tefjel or similar to prevent galvanic corrosion and siezing. That applies to all fasteners on board.

A good preparation to use on threaded (into metal) fasteners is Marine Never-Seize. If you can't get the marine flavor, substitute the automotive store variety that says on the label that it can be used on boat equipment.

That Tefgel is good stuff, had to use it all over an aluminum boat being refit, definitely helps getting hardware off. And dabbing a bit extra on your finger, washers and nuts helps for those times when you can't see what you're doing.
Guy from tech support there even recommended using it to dip stripped wires before crimping on a terminal...

Dura-Loc is another kind, probably a lot cheaper, but you'll be getting the yellow everywhere.

TefGel, LanoCote or anhydrous lanolin are all good choices to help prevent corrosion. If you've got bronze hardware, your best bet for fasteners is silicon bronze fasteners from Jamestown Distributors.

Don't use brass on the exterior of a boat... it will dezincify and then you're screwed.
