摘要：
A breakstem blind rivet comprises a deformable tubular shell (11) of aluminium alloy having a bore (12) inside it. A stem (13) of low-carbon steel is a close fit within the bore, extending along the bore and having a head (14) adjacent the tail end (15) of the shell. The outside of the shell is formed with at least three zones (27, 28, 29) of modified strength spaced apart along its length, these zones being in the form of shallow grooves rolled into the surface. The spacing between each zone (27, 28, 29) and the next progressively decreases as the distance along the shell from the tail end (15) increases. Alternatively the grooves may be formed by a turning process.
