Abstract: A blind rivet (10) comprising an elongate hollow rivet body (11) having a head end (12) and a tail end (15) and an elongate mandrel (13) having a head end (14) located adjacent the tail end (15) of the body (11). The mandrel (13) has a stem (16) extending through the hollow body (11) and the stem (16) has a tapered portion (17) adjacent the head (14) of the mandrel (13) that tapers towards the head (14). The stem (16) has a distal end that projects beyond the head end (12) of the body (11). The tapered portion (17) of the stem (16) is provided with a plurality of axially spaced grooves (18 to 20) that define between them ribs (21 to 23) that have a profile comprising two axially spaced ridges (25, 26) subtending a concave circumferential surface (24) between the ridges (25, 26). The body (11) is of substantially uniform outer diameter and has a thicker wall thickness over the region (17) corresponding to the tapered section (17) of the mandrel (13).
