Generic Grade 8 Bolts???

So... today I was doing some work on the Jeep and had a sway bar link disconnected. I buggered the threads while I was putting back on. So I could drive it right away, I went to the hardware store and bought a generic, anodized, grade 8 nut and bolt.

The bolt is a little longer than the original and the color doesn't match the rest of the bolts. It seems to be working fine, but the OCD in me knows its wrong and even though I can't see it, I want to change it. However, the bolt from the hardware store was $1 and the factory replacement from the dealer is $10.

Should I leave the generic bolt in there? Will it last for 50 years or is the weather going to rust it out in a few years? Should I buy the correct bolt because its "the correct bolt" or do I save my money?

When you said anodized, do you mean it was zinc plated (a bit of a gold-ish coloring?). Zinc is a rust resistant coating. Not rust proof, but not like a bare steel bolt either.

Should be totally fine. I wouldn't worry about it at all. Everybody is bothered by different things, and I'm extremely picky about certain things. This situation wouldn't bother me a bit.

Yes, anodizing is an oxidizing process on aluminum; your bolts probably were galvanized.

Sorry guys... I misspoke... I believe they are zinc (yellowish gold color). Its not labeled on the package, but I figured it was some type of coating.

I didn't realize anodize is specific to aluminum.

All steel will eventually corrode. The Zinc plating and the yellow chromate coating on it only slow that process down.

The bolt you bought will be just fine.

You are replacing a metric 10.9 bolt with a standard grade 8. They are not the same size. Close enough that it will be fine, but at a minimum I would replace both sides so they use the same size wrench.

Could be cadmium plating.

Thanks for the feedback guys. I think I am going to put some grease on it to help prevent the bolt from rusting into the sleeve. Chances are, I'll be the next guy working on it. Might as well stack the odds in my favor.

That is the kind of stuff that bothers me. Not the same color, length, head size, etc. That is what is pushing me to replace it more than anything else. I hyper-focus on stuff like that to the point that its drives me nuts. LOL

I'm hoping after a few weeks I forget about it. Knowing it will be ok helps me overcome that urge. The satisfaction of not giving the dealer $10 helps too.

Most shops don't do cadmium anymore, too many restrictions by the epa. We do a yellow chromate conversion coating on top of zinc if you want yellow parts.

Why don't you just buy a graded metric bolt from the hardware store? it won't be 10 bucks....

I went to 3 hardware stores in my area and couldn't find the right size. The standard is just a fraction of an inch smaller, but almost perfect, so I decided to buy the standard before I spent $10 in gas trying not to buy a $10 bolt.
