A blind rivet includes a hollow rivet body having a longitudinally extending indented groove. The groove may be shaped to impart rivet setting characteristics that may be varied to provide desirable fastening characteristics for joints in a number of industries. The shape of the indentation on the rivet body may be varied to cause a portion of the rivet body to collapse and form a secondary head at a predetermined longitudinal location.

Blind rivet and method

A multi-grip blind rivetincludes a rivet body, adapted to receive a portion of a mandrel. 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.

Multi-grip blind rivet

A fastener includes an axial shank and a clamping face extending radially from the shank. A plurality of serrations are formed on the clamping face and extend radially from a shank periphery to an outer periphery of the clamping face. The shank periphery is axially displaced away from the clamping face relative to the outer periphery of the clamping face to define a ramped surface.
