摘要

A self-drilling and blind setting rivet assembly for power tool application to workpiece means including a hollow rivet sleeve with an enlarged head at one end. A mandrel with a drill point at one end positioned through the bore of the sleeve so that the drill point on the mandrel is positioned adjacent the end of the sleeve opposite the head portion. The mandrel shank will have a weakened portion of reduced cross- sectional area with the inner periphery of the sleeve and outer periphery of the shank including cooperating torque transmitting surfaces on either side of the weakened portion of the shank to allow torque to be applied directly to the shank with the torque transmitting means serving to bridge the weakened portion of the shank to enable the drill point to drill a hole and yet allow the shank to fracture upon appropriate tensile force during the setting operation.
