I've heard people talk about a rule of thumb that bolt heads are to be on the forward or upper side of a bolted connection, but I cannot find anything in AC43.13 about that. Also, I'm having trouble with the logic of such a rule if the builder ensures a proper torque on the joint, but I don't need to come up short on this in a tech inspection.

And if there is such a rule, would it apply to riveted joints (mfg head fwd/up), or is it simply better to form the shop head against the thicker material of the joint?
