Abstract

A blind fastener comprises a tubular member slotted so as to be radially expandible by a core member (10; 37; 38) extending through it. In one embodiment, the tubular member is externally threaded, and a first nut (14) is threaded on the core member (10) and engages the tubular member (11) so as to cause expansion of the latter as the head (16) is drawn into the tubular member (11). A second nut (19) on the tubular member (11) is tightened in order to complete a fastening operation, but the inner size of the second nut (19) is greater than the outer size of the first nut (14) so that the second nut (19) can be withdrawn over the first nut (14) for dis-assembly purposes. In a further embodiment, the tubular member (30) has a head (33) and a threaded core member (38) extends through the tubular member (30) and engages an internally threaded core head (37). <IMAGE>
