Are you sure the front bumper bolts aren't any bigger than a 10mm?? The ones holding mine on are HUUUGE, but mine is an aftermarket bumper as well. Does the JCR bumper come with unibody tie ins on it? I would use the biggest, and highest grade bolts you can fit in there. Especially if you intend to use the front bumper as a recovery point. It wouldn't hurt to give JCR a call, and see what they recommend.
dont use grade 8 bolts in a bumper theres no bend they just sheer off if you put the right force to them the grade 5 bolts will bend before they brake. 10 mmis the size if the bolts not the head lol mine were 10mm in both frt and rear bumpers. i think x2elite is right about calling JRC and asking them!

Did you even read the articles? That exact myth is explained in both of them. Under the same loading conditions BOTH grade 5 and grade 8 bolts will bend before they break.
What were you doing that you broke the bolts in your bumper once and then almost broke them again?
Don't get me wrong, I don't know anything about your application and I'm not saying grade 5 won't work. Just saying that the theory you are basing your selection on is not correct.

Hardware stores will have grade 5 and grade 8 bolts as well. I prefer Lowes...they seem to have a better selection of bolts/fasteners than Home Depot or McCoys. Last time I was at Lowes they had grade 5 3/8" bolts up to 4" long.

I've never really looked close at TSC's bolt inventory...though from what I remember it seemed pretty decent. Just make sure you're not getting grade 2 or "hardware grade" fasteners.

TSC by far has the best bolt selection out of the mentioned stores. They have what you are looking for as thats where I got mine but I dont remember the size.
