There is provided a blind rivet including an axially extending hollow tubular body having a tail end face at one end and a pre-formed radially enlarged flange at the other end, together with a mandrel having a stem which extends co-axially though the body and having enlarged head adjacent the tail end of the body, the stem having a weakened region immediately adjacent the head. There is also provided a method of fastening at least two workpieces using such a blind rivet, including providing the blind side of the workpieces with a countersunk region to accommodate the conically deformed tail end of the body after setting, substantially flush therewith.
