The term rivet is used to describe a variety of fasteners with a couple of common traits. They are pre-shaped at one end and have their other end reshaped when they are put to use. All have a smooth shaft that passes through the materials being bonded.They are used to join two or more materials together and form a joint that is stronger and tighter than a screw of the same diameter could be.ecause the shaft of a rivet is smooth, it is better at resisting side-to-side motion (called shear) than a screw or bolt of the same diameter. Consider a screw and rivet passing through two pieces of metal; 100 percent of the rivet is in contact with the metal, while the screw touches half or less.
