Abstract
In a blind self-plugging rivet of resilient nylon-66 material the stem head has an annular projecting barb adjacent the breakneck, and the shell has a short counterbore at its head end into which the barb expands, when the stem head is fully pulled into the shell, to assist in locking the stem head in the shell. At its tail end the shell bore has a plurality of annular faces arranged step-wise, to engage behind the end face of the stem head over a range of possible positions of the latter depending on the thickness of the riveted members.
