Why are special fasteners used over solid shank rivets?
Although the shear loads of riveted joints are very good, the tension, or clamp-up, loads are less than ideal. Special purpose fasteners are sometimes lighter than solid shank rivets, yet strong enough for their intended use. Typically, the locking characteristics of a blind rivet are not as good as a driven rivet.
