A novel fastener is provided which includes an expanding sleeve for receiving a pin where the pin has shank terminating at a first end in a pin head and terminating at a second end in an externally threaded portion of the pin. The expanding sleeve may include a hollow tubular shank terminating at a first end in a sleeve head and having an opening at a second sleeve end for receiving the pin. The sleeve head include an internal sleeve head surface for engagement with an external pin head side surface when in an assembled position. When the pin and expanding sleeve in the assembled position are inserted into an aperture in a structure, a gap is formed between the aperture and an outer surface of the expanding sleeve. The outer surface of the expanding sleeve radially expands outward into the aperture filling the gap upon engagement of the internal face of the sleeve head and the external pin head surface.
