ABSTRACT:
A fastener bushing for use in a panel structure consisting of a pair of spaced outer skins and a low density core therebetween is formed with an elongated shank adapted to be inserted through an opening in the panel. The shank has a longitudinal bore extending therethrough in which a fastener element can be inserted and includes an integral enlarged head formed at one end thereof which will overlie the skin along one side of the panel when the bushing is inserted in the openings. The bushing has a peripheral groove formed on the shank immediately below the head so that when the shank is fully inserted in the panel, the groove receives the edge of the opening through which the shank was inserted, thereby to positively retain the fastener bushing in the panel.
