Keep in mind that for a bolted joint you are designing its preload such that it is higher by some safety factor than the combination of forces on the joint's bolt pattern. As long as the bolts in the joint have preload in the joint, and there is no shear sliding in the joint, any single one of the bolts cannot have a moment on it (other than torsion caused by tightening). Instead, the applied moment is spread accross the bolt pattern as compressive and tensile forces (or shear as the case may be).
