I need 2 new torque arm bolts, but GM wants $13 each for them. I'm probably going to just order something locally. What is stronger, a grade 8 bolt or stainless. I know it depends on what grade of stainless, but I just want a good idea. Thanks.

 

I don't know for sure, but I would think stainless bolts would be graded the same way.

If your buy your parts from Jason or Dal, you will pay about half of what you posted.

 

grade 8 bolt

stainless are typically grade 5 or cheaper-









worked in smalltown hardware store for 6 years now

 

What he said. Stainless is a very soft metal. They're not nearly as strong as some of the hardened moly and silicon steels available. (Grade 5 vs grade 8... 7.9 vs 12.9 metrics)

 

That could get ugly if the cheap bolts decided to break

 

Been there, done that. Well they didn't break, they fell out. Guess I didn't tighten them enough. It had to happen on a curve when I decide to pass someone. It bent the bracket on my new BMR TA, I was able to bend it back by bolting it up. Right now I just have some regular bolts from lowes. I don't want to chance them too long.

 

Stainless is usually a grade 2 i believe
