Description

Technical Field

[0001] The present disclosure relates generally to fastener systems for joining multiple substrates of a workpiece, and in particular to fastener systems that provide an interference fit with a workpiece including one or more composite substrates. The conductive properties of various fastener systems provide protection from electromagnetic effects.
