Dieses Dokument legt die Eigenschaften einer Sechskantkopfschraube mit Flansch, mit Innensechsrund, aus Verbundwerkstoff für Kabinen- und nichttragende Anwendungen in der Luft- und Raumfahrt fest. Aufgrund des Polymerwerkstoffs können die Schrauben auch verwendet werden, um Beschädigungen von Lack und Beschichtungen unter der Unterlegscheibe beim Anziehen der Schraube zu vermeiden.
