Zinc Plated or Galvanized

God
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?
 
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??
 
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.

Hey Mulv,

I have been overhauling my tandom EZ Loader trailer and have been buying my parts from Eastern Marine in Newark DE. So far I have replaced all four drum brake assemblies, jack, winch cable, lights, surge brake coupler, both equalizers and replaced all brake lines with stainless steel lines. Yeah, I know, I should have replaced the drum brakes with disc brakes, but right now, money is an issue. As you know, I have a leaky 60 gallon fuel tank to fix or replace and some regular engine maintenance issues to perform before striper season. I know you live in the Philly area and the reason I mentioned Eastern Marine is the quality of the parts they have supplied me so far, price, and the quick delivery. If I order on-line, and select UPS Ground, (cheapest) I receive the parts next day in Doylestown PA. I haven't ordered parts such as u-bolts yet but EM also has hot dipped and stainless steel fasteners.

Hey Ed, Glad to see you here on the site. I'm familar with Eastern Marine, their prices are the best around in my opinion. I ordered these bolts hastily over Ebay because they were cheap and it looks like I may have gotten what I paid for.
 
What about Boaters World ??? Herad that there was one in Newark I guess, or Wilmington. Across from the airport on rt.13. I was gonna check it out on Wednesday.
 
Zinc plated stainless is one thing, but "zinc" as far as I know are the standard grade bolts that any hardware store (lowes, Hdepot) would carry.

I could be wrong, its happened before...hey once I met this guy Skools and I thought he was a fairly "normal" guy. ::) ;)
