Abstract
A split-setting pull-type blind-riveting assembly comprising a hollow rivet and a mandrel. The underside of the mandrel head is frusto-conical and terminates at flat surfaces normal to the mandrel stem. A portion of the mandrel stem adjoining said plane is squared off so that its corners deform the rivet shank before the underside of the mandrel head splits it into petals. Reliable splitting of the rivet shank into uniform petals is thereby reliably achieved.
