ABSTRACT:
An improved insert fastener for use in lightweight panels is described. The fastener has a flat circular head overlapping a hole in the panel. Integral with and depending from the head is a cylindrical body with a pair of radial flanges parallel to each other and to the head. The flanges are spaced apart from each other and the head. The edges of the flanges are serrated. A central threaded bore through the head and cylindrical body receives a bolt for holding auxiliary structures to the panel. Two holes, one on each side of the central bore, are present in the head to allow excess epoxy resin potting material to leave the hole in the lightweight panel.
