Abstract
A removable blind fastener includes an anti-rotation body having an external face with an aperture, the external face being suitable for engaging with a surface of a work-piece to be clamped. The fastener further includes a hollow leg member with a plurality of slots defining outwardly biasable resilient legs at one end and an externally threaded portion at the other end, the leg member having a bore tapering towards the legs, the leg member being translatable through the aperture, the leg member and the aperture further having inter-engaging anti-rotation features to prevent the leg member from rotating about its central axis relative to the anti-rotation body. The fastener may further include a thread tube with an internal thread cooperable with the external thread of the leg member and located co-axially with the leg member and a rod member having a shaft with a head end and a free end.
