Galvanised washers where to get?

Anyone got suggestions where I could get some value 22mm washers for my trailer.

That's what was on the trailer before and they've only lasted 3 years. Might just get Stainless steel ones and be done with it.

It could have a negative influence with the rest of the stuf no stainless!!!!
the other stuf will saccrifice.

That's just what I'm doing...did some a while ago, doing the rest now :-) Not seen any negative effects

That's what I thought, was talking to someone I bumped in to down a local Boat Jumble this morning and he didn't think there would be much of a problem with Stainless.

This has been debated before...there's the theory of a problem but the reality from those who have done it is there's no problem. You pays your money...

Be careful with stainless on galvanised.

The galvanising in contact with the stainless will corrode quite quickly, leaving the underlying steel open to the elements - causing rust staining.

We see it all the time with galvanised chain shackled to a galvanised anchor with a stainless shackle.

The OP was asking about galvanised washers v stainless washers on a trailer. I've replaced all the rusty galvanised washers on my trailer with stainless ones. No rust anywhere after several years.

My experience of galvanised washers from the day job is that the galvanising process on such relatively small, low value, high volume parts is that it's variable at best and p$ss poor at worst

I think the other thing to consider is that a trailer will only be in the water for a short amount of time, doesn't electrolisis have something to do with disimilar metals corroding?

Yes, but there will inevitably be salty moisture lingering between close fitting parts (ooer

) so it won't just be when the trailer is being dunked. The moisture may dry out, probably leaving salt deposits, which will rehydrate (think that's the word!) if it gets fresh water on again. What happens to brakes when you dunk the back of a vehicle in salt water when launching is a good example.

That's good feedback.

If you haven't done it yet, think about nylon ones too. If they're not load bearing, it could be a cheaper alternative for you.

I would have liked Nylon Washers, but I don't have the clearance on the shaft to fit them as they'd be too wide. Thanks for the suggestion though.

I have a galvanised trailer with stainless nuts and bolts all over it. I have had it for at least Ten years, I give it, and the boat a swill with fresh water every time I use it. And so far I have not seen any rust, or had any problems with it.
