Aerospace series - Nuts, anchor, self locking, two lug, floating with counterbore - Classification: 1100 MPa/235 °C
This standard specifies the characteristics of two lug, counterbored, floating anchor nuts, with a self-locking feature achieved by forming the upper portion out-of-round, the dimensions of which are in conformity with ISO 3209. These nuts are intended for use in aircraft assemblies, in which the fasteners are mainly subjected to shear loads. The counterbore of nuts with thread diameter equal to or greater than 4 mm is deep enough to accommodate a bolt shank in excess of assembly thickness, as well as the incomplete threads. The 3 mm diameter nut has no counterbore. They are intended to be used with threaded parts of 1 100 MPa 1) tensile strength classification. The cadmium plating restricts the application to temperatures not exceeding 235 °C.
Luft- und Raumfahrt - Gehäuse-Annietmuttern, selbstsichernd, beweglich, beiderseitiger Flansch mit zylindrischer Aussenkung - Klasse: 1100 MPa/235 °C
Diese Norm legt die Eigenschaften für Gehäuse-Annietmuttern mit beiderseitigem Flansch, zylindrischer Aussenkung, beweglich, selbstsichernd durch den unrund geformten oberen Abschnitt mit den Maßen nach ISO 3209, fest.
Diese Muttern sind für die Anwendung bei der Montage von Luftfahrzeugen vorgesehen, wo die Verbindungs¬elemente hauptsächlich den Scherbeanspruchungen ausgesetzt sind. Die Aussenkung von Muttern mit Gewindedurchmesser gleich oder größer 4 mm ist tief genug, um einen Bolzenschaft, der länger als die Dicke der zu montierenden Teile ist, sowie unvollständige Gewinde aufzunehmen.
Die Mutter mit einem Durchmesser von 3 mm hat keine Aussenkung.
Die Muttern sind für die Anwendung mit den Gewindeteilen der Zugfestigkeitsklasse von 1 100 MPa ) vorge¬sehen.
Das Verkadmen begrenzt die Anwendung auf Temperaturen nicht höher als 235 °C.
