Recovery hook hardware requirements?

Hey guys. Looking to add recovery hooks to my front bumper, and plan to purchase the CURT branded ones that are available on amazon for about ten bucks per.

I'm wondering - can I use my factory TORX bolts or will I want to upgrade to grade 8 hardware? Or maybe the factory bolts are too short for the added .75" or so from the hook? Hell, for all I know the factory bolts ARE grade 8 rated. But I don't know.

P.S. I assume it's an easy install? Just take a peek under there, find the nuts, take everything apart and put it back together with the hooks and new hardware? Do I need to support to bumper or can I just do one side then the other?

Thanks in advance.

If the factory bolts are long enough they are strong enough. Just measure and be sure you have enough length. Grade 5 will work too.

Edit: I think a single grade 5 bolt is almost twice the strength of the curt hook

Wow, love to hear that. Why then, I wonder, is it so common to see grade 8 recommended? I guess overkill can't hurt if you're already buying?

Your answer is in the sentence that follows your question. Some people automatically assume that Grade 8 must be "better" than grade 5 without understanding why that might or might not be the case for a particular application.

These links will fuel the debate:
