ABSTRACT:
A fastener and an associated fastening method are provided to securely join at least two structural elements to form a structural assembly. Although the fastener can join a variety of different types of structural elements, the fastener is particularly well adapted to join composite panels, superplastically-formed/diffusion-bonded panels, honeycomb panels and hollow core panels since the fastener can securely join these structural elements without crushing or otherwise damaging the structural assembly. The fastener can also be mounted in blind installations, while providing a relatively smooth head following installation. In addition, the fastener can securely join structural elements while tolerating variations in the thicknesses of the structural elements.
