A plurality of indentationsare formed in an outer surfaceof the rivet bodyin each of three axially spaced transaxial planes. Each indentationis formed with a work hardened base surfacehaving a convex portion, which is formed with axially spaced first and second transaxial edgesandhaving nonlinear portions. Adjacent indentationsare separated by ribs. A flared intermediate surfaceextends between the base surfaceand the outer surface. The rivetis assembled within aligned holesandof workpiecesand, respectively, where, upon setting of the rivet, the indentationscollapse and the outer surfacebulges against walls of the holes to retain the workpieces together.
