ABSTRACT:
A method for mounting an insert fastener to accommodate a bolt in lightweight panels is described. A hole is bored in a panel to penetrate the core and upper facial sheet and then is filled with a quick setting resin. A fastener having a flat circular head and central threaded bore is inserted into the hole. 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. Two holes, one on each side of the central bore, are present in the head to allow excess resin potting material to leave the hole in the lightweight panel. A bolt for holding auxiliary structures to the panel is screwed into the central bore.
