A rivet setting tool for use with double headed blind rivets comprises a collet assembly adapted to engage a pulling head of the rivet, and abutment members movable between an open position, in which the pulling head of the mandrel of the rivet may be passed through the abutment assembly to be engaged by the collet assembly, and a closed position in which the abutment members provide an abutment to engage the rivet head. The abutment members are mounted for generally axial movement and when a double headed blind rivet is presented axially to the tool, the head of the rivet engages the abutment members, and on the rivet being pushed into the tool so that the pulling head is engaged by the collet assembly, the abutment members are moved axially and are caused to close firmly about the mandrel.
