ABSTRACT:
An expanding bush and captive bolt assembly (1), comprising a bolt (2), a generally cylindrical bush (4), and a ring clip (6) that retains the bush on the bolt. The bush (2) has an inner surface with a portion (22) that has a frustoconical taper, a channel (12) that extends circumferentially inside the bush, and an expansion split or slot (7) so that the bush may be expanded radially. The bolt (2) has a threaded portion (10) for engaging with a socket that has a matching thread, a head (8) by which the bolt may be rotated to tighten the bolt (2) to the socket and to squeeze axially the bush (4), a shaft (18,20,23) between the head (8) and the threaded portion (10), said shaft having a portion (20) with a taper that engages with the tapering portion (22) of the bush to expand the bush (4) as it is squeezed axially between the taper (20) and the socket, and a channel (16) that extends circumferentially around the shaft and which opposes the channel (12) of the bush. The ring clip (6) is seated between the bolt (2) and the bush (4) and is engaged with both channels (12,16) to retain the bush (4) on the bolt (2).
