Bolts with a locking feature, such as a normal lock washer, properly torqued, will NOT loosen because of twisting or the whole world is in trouble! I don't think anyone would install a bolt without a couple flat washers, a lock washer and a nut. America has been bolting stuff for a 100 years. A grade 5 is plenty, plenty strong for AD/TF frame components. I don't care if a person uses bolts or rivets, just clarifying some info. Grigg: This is a family show. (PG13), whoa! there horsey! We know what crooked and offset means.
Bolting on something like an engine part is different than thin sections of frame. Again the bolts in the same hole as a rivet can not be as strong cross section!
