摘要: A blind rivet for fastening apertured sheets comprises a tubular shell having a head at one end, and a mandrel having an enlarged head which when pulled into the bore of the shell deforms the shell to produce a blind head. The mandrel has a breaker groove at which it breaks when the rivet is fully placed, leaving the mandrel head plugging the shell. The mandrel head has an integral peripheral skirt which can be deformed outwardly by a tool used for placing the rivet, so that the skirt engages the shell and prevents the mandrel head from being pushed out of the bore of the shell. The mandrel head is adapted to wiredraw after the blind head has been formed so that the mandrel will break substantially flush with the head of the shell when fastening either thick or thin sheets.
