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.
