摘要： A self plugging blind rivet (i.e. one in which at least a portion of the stem remains in the shell after installation so that the shell bore is thereby plugged) has a stem having a shank (26) which is provided with an annular shoulder (38) which, when the stem is drawn into the shell, engages with an annular shoulder in the shell bore to deform material of the shell into the space between the stem shoulder (38) and a radially projecting locking ring on the stem shank, so as to look the stem into the shell. The locking ring of this rivet is formed of two part-circular portions (34, 34′) separated by gaps (36). These gaps allow deformed material of the shell to flow through them if necessary, thereby enabling the stem to be drawn further into the shell. This extends, at its lower end, the range of total thicknesses of workpiece which the rivet can satisfactorily join together.
