Abstract: A fastener and an attachment assembly. The fastener includes a bolt having a first bolt portion, a second bolt portion and an intermediate bolt portion arranged between the first bolt portion and the second bolt portion. The first bolt portion is conical and the second bolt portion is threaded. A first bushing has a conical inner surface arranged in circumferential abutment to the first bolt portion and a nut to be threadedly engaged to the second bolt portion. The attachment assembly secures objects to each other and includes at least two bores, arranged through the objects, including a first bore portion, a second bore portion and an intermediate bore portion, respectively. The intermediate bore portion is arranged between the first bore portion and the second bore portion. The attachment assembly also comprises at least two fasteners, each fastener is arranged inside the bores, respectively.
