Abstract
A blind rivet includes a mandrel shaft having a head disposed at one axial end. A hollow rivet shell has a cylindrical shape including an inner cylindrical surface and an outer cylindrical surface. The rivet shell surrounds the mandrel shaft. The outer cylindrical surface has at least one attenuation groove, which includes at least two recesses. Each recess has a bottom surface that substantially forms a secant with respect to the outer cylindrical surface. A method of manufacturing a blind rivet comprises the steps of placing a mandrel shaft having a head within a hollow rivet shell, producing at least one attenuation groove in an outer cylindrical surface of the rivet shell after the placing step so that at least two recesses are formed. Each of the recesses has a bottom surface that substantially forms a secant with respect to the outer cylindrical surface.
