Abstract
A blind fastener having a body, a core bolt, a nut and a sleeve. The core bolt passes through an axial bore of the body and includes an externally threaded portion at an inner end thereof. The nut has an enlarged head, a reduced diameter stem and a threaded bore for engaging the threaded portion of the core bolt. The sleeve is located between the enlarged head of the core bolt and a conically shaped inner portion of the body. An inner end portion of the sleeve is fixed to the stem of the nut. In a preferred embodiment, the inner end portion of the sleeve is crimped to the nut and has a thickness sufficient to engage the nut across the full width of an annular shoulder of the nut during setting of the fastener.
