There is provided a blind fastener (1). The blind fastener (1) comprises a bolt part (11), a sleeve part (12), and a tubular insulating sheath (13). The bolt part (11) is at least partially received within the sleeve part (12). A first end (131) of the sheath (13) is retained on the bolt part (11) such that relative axial movement between the first end (131) of the sheath (13) and the bolt part (11) is substantially prevented. The blind fastener (1) is movable between: a pre-installation configuration in which the sleeve part (12) has a first axial position relative to the bolt part (11) and a predetermined section of the sheath (13) is adjacent an outer surface of the sleeve part (12); and a post-installation configuration in which the sleeve part (12) has a second, different axial position relative to the bolt part (11) and the predetermined section of the sheath (13) is adjacent an inner surface of the sleeve part (12).
