I have a box of them as well, and they are a hell of a lot better than the crap that WARN supplies with their hubs. They're something like Grade12 bolts if we're talking about the same ones. The box came with the Xterra I bought, and only had about 10 left in it...but they're damn good quality. Thanks for the info, as I'm sure I'll be looking to order more for spares.
