Installing winches. Which metal to use?

Hi everyone. A quick question. I have a pair of bronze barients I'm installing in my ericson 32. Should I bother to match with bronze screws and nuts or just wing it with stainless steel? I already found the stainless. But the bronze I only found the screws and nuts --- could not find oversized washers etc.

The concern is dissimilar metals.

Many thanks.

Re: Installing winches. Which metal to use?

Most bronze and stainless alloys are reasonably compatible so I wouldn't be too concerned about mixing these two. Al and SS or Al and alloys containing copper (brass, bronze) on the other hand are not so good.

Re: Installing winches. Which metal to use?

If it is where you could see it, even if it is compatible, it would look tacky to have SS washers with bronze bolts/screws IMO. Jamestown Marine has a good selection of hardware in a variety of metals, e.g.

Silicon Bronze Flat Washers

Our local hardware store also has a variety but we are in a very marine friendly town.

Imho SS is OK on bronze. Do use lanocote or similar passive grease (duralac, boeing, etc.) in between.

Ok so ss sounds like a good idea. Thanks for the feedback. It's not cosmetic. The screw heads are hidden by the winch itself and the nuts are on the underside.

I also found Jamestown to be a good source for bronze bolts, washers, screws and such. Not cheap but they carry a good selection.

Re: Installing winches. Which metal to use?

A question. You don't mention a backing plate for the winch. Do you have one, & if so, is it Bronze?
Obviously, they're not mandatory for every winch & application. Though they rarely (if ever) hurt. But if you do have one, then having all of your fasteners matching it adds an air of class to the boat. Ditto on simply having your washers match up with your bolts & nuts.

IMO, a shiny, well polished Bronze backing plate for winches, definitely adds to almost any boats belowdecks looks. And some Bronze backers (plates), can even be clear coated, in order to cut down on maintenance.
Plus, if you like, with a backer of any thickness, you can simply tap it for the bolt threads. And then add acorn nuts, in order to remove the sharp(ish) points on the bolt ends. Thus negating the need for some of the fasteners which you're inquiring about.

How to make a simple job into a production.

Fender washers are all the backing you need for a winch. SS fasteners work just fine unless you plan on storing your boat inverted in the water so the winches will be totally immersed all the time. Even then it wouldn't be much of a problem. If you use an aluminum backing plate, sand it thoroughly and coat with zinc chromate primer before installing. That will insulate the aluminum from the SS fasteners and stop the aluminum from developing that rough oxidized appearance and corrosion pitting from the salt air.

If you are using backing plates then just use G10. But I really wouldn't use an aluminum backing plate with stainless fasteners. Sure it will work, but G10 is easy to work with and eliminates galvanic corrosion completely.

Re: Installing winches. Which metal to use?

Thanks everyone. I went with ss. I got oversized washers so we should be ok. Tempting to get a thick backing plate out of bronze and tap it but I'm not that good with drilling straight into the boat without a drill press so washers it will be.....
