ABSTRACT:
A fastener element is ejection molded from an engineering resin of a type that will bond to potting resin used for securing the fastener element within a cavity formed within a panel of composite material. The fastener element includes flow control disks spaced apart along a stem portion between end portions. Flats are formed on opposite sides of the flow control disks, below fill and vent openings. Resin introduced into the fill hole travels down to the bottom of the cavity and around the fastener element and fills the cavity from the bottom up, so that the presence of resin at the vent opening will indicate that the cavity has been filled with resin and does not include an airspace or void.
