Abstract
Fastener, e.g., stud, installation in a composite panel, such as a graphite epoxy structure having a longitudinal electrical conductivity substantially greater than the transverse electrical conductivity, is achieved in a manner providing increased conductivity between fastener assembly and the panel to which it is attached. Through panel countersink and fastener configurations, e.g., by use of frustro conical countersink to spherical fastener surface configurations, increased electrical contact is made to conductive fibers in the composite material which run at right angles to the central axis of the fastener.
