One-sided fastener assembly and methods and systems for installing the same

Abstract:

A one-sided fastener assembly for use in coupling an assembly stack-up includes a sleeve comprising an outer cylindrical surface and an inner tapered surface oriented at a first angle with respect to the outer surface. The inner tapered defines an opening extending through the sleeve. The fastener assembly also includes a core extending along an axis and configured for insertion into the opening. The core includes an outer tapered surface oriented at a second angle with respect to the axis configured for engagement with the sleeve inner tapered surface such that insertion of the core into the sleeve causes radial expansion of the sleeve creating an interference fit with the assembly stack-up to complete installation of the one-sided fastener assembly.
