Short version: Is there such thing as a grade 8 pinch/top/crimp lock nut? Not a nylock, the steel lock nuts. Long version: I'm putting my beadlocks together this weekend and nobody has enough of the specific hardware I need except for two fastenal's. One says they have 50 of the grade 8 pinch locks on hand, the other says there's no such thing as a grade 8 pinch lock but they have plenty of the "normal" (I assume they mean grade 5) ones. These nuts and bolts are holding my tires to my rims so it's not a place to skimp. Anybody know the story?
