map guy, skinnyme said his 16k has 10.8 bolts, what standard thread bolt would that compare to?
google says 10.9 about equal to grade 8

So grade 5 equivalent?
B&W uses Grade 8 bolts with locking washers, NO flat washers. They have 4 bolts each side compared to 2 each side on the CURT. I do believe the bolt diameter is a bit larger with the CURT???
