<p>A fastener element (70, 104, 120) is injection molded from an engineering resin of a type that will bond to potting resin (68) used for securing the fastener element (70, 104, 120) within the cavity (24) formed within a panel (12) of composite material. The fastener element (70, 104, 120) is constructed to include disks (80, 82, 106, 122, 124) spaced apart along a stem portion (76, 108, 128), between end portions (72, 74, 130, 136). Flats (90, 92, 93, 95, 114, 116, 118, 138, 140, 142, 144, 146, 148) are formed on opposite sides of the fastener element (70, 104, 120), below fill and vent openings (94, 96, 110, 112, 132, 134). This construction results in resin travel down to the bottom of the cavity (24) and around the fastener element (70, 104, 120) and a filling of the cavity (124) from the bottom up, so that the presence of resin at the bent opening (96, 112, 134) will indicate that the cavity (24) has been filled with resin and does not include an airspace or void.</p> |
