I got mine at Lowe's in Carson City, NV. HD did not have them when I was there. Same city.
My understanding is they are shear bolts. Someone said the stainless are not quite as strong as the grade 8. I'm not an expert. I'm just repeating what has been said in MOC on this in the past.
There are several posts from the Lippert expert, MIMF, about this and those are the bolts he says to get. So I think we already have the expert opinion.
See another Montana or Mountaineer on the road? Flash lights twice, it might be one of us!
