Zinc Plated or Galvanized

[Mulv80]

I bought some U-Bolts off of Ebay for my trailer. They were advertised as galvanized but when I received them they are clearly zinc plated. Will these U-Bolts hold up to harsh saltwater use?

yes that's what Yamaha ships with their new Saltwater motors to mount them with, Zinc will be better than Galv.

Thanks Skools, I was just about ready to fire off an email to the seller.

Skools, i love you but ZINC over Galvanize???

WTH are you talking about? "Zinc plated" are regular grade bolts. They will rust in ONE trip!! NO??

[phester]

I thought two dissimilar metals in any application is a no no...?

Ok, new wrinkle to this post. I emailed the seller and he said the bolts are ElectroGalvanized ??? I googled the term electrogalvanized and it does exist, as far as its resistantance to saltwater corrosion I dont know?

ok Stink's i looked at the ones i have from Yamaha. They are Zinc coated stainless bolts. but avail. in Zinc grade 5 bolts too. But the Zinc on their bolts is super thick. I have them in my trailer and not spec of rust yet n there grade 5 zinc's. Nice shinny new looking bolts lol. Depends on the amount of coating of Zinc.

Hi Mulv,

See this web page:

According to studies, zinc plating has much less corrosion resistance than other zinc coatings. Check it out!!
