Abstract
A blind rivet having a mandrel with a predetermined breakable stem (4) disposed within a body with a bored (18) shank (14). A radial flange (16) is formed on one end of the shank and the other end (20) of the shank is engaged with the enlarged head (2) up the stem the diameter of which is substantially equal to that of the shank. The mandrel below the enlarged head has a plurality of indentations (8) formed on the stem to define a square of reduced cross-sectional area. The shank has an enlarged internal cross-sectional area (22) to substantially engage the indentations of the stem below and adjacent to the enlarged head of the stem.
