Aerospace series - Nuts, anchor, self-locking, fixed, closed corner, reduced series, with counterbore - Classification: 1 100 MPa/235 °C

This standard specifies requirements for closed corner, counterbored, fixed, reduced series anchor nuts, with a self-locking feature achieved by forming the upper portion out-of-round.
These nuts are intended for use in aircraft assemblies, in which the fasteners are mainly objected to shear loads. The counterbore is deep enough to accommodate a bolt shank in excess of assembly thickness, as well as the incomplete threads.
They are intended to be used with threaded parts of 1 100 MPa  ) tensile strength classification.
The cadmium plating restricts the application to temperature not exceeding 235 °C.

Luft- und Raumfahrt - Annietmuttern, selbstsichernd, einseitiger verküzter Eck-Flansch mit zylindrischer Aussenkung - Klasse: 1 100 MPa/235 °C

Diese Norm legt die Anforderungen fest, für unbewegliche Annietmuttern mit einseitigem verkürzten Eck-Flansch, zylindrischer Aussenkung und einer durch Verformung des oberen Teiles erzeugten Selbstsicherung.
Diese Annietmuttern sind in der Luftfahrt für Verbindungen bestimmt, bei denen die Verbindungselemente hauptsächlich Scherbeanspruchungen ausgesetzt sind. Die Aussenkung ist tief genug, um eine über die Dicke der Verbindung hinausgehende Schraubenschaftlänge sowie den Gewindeauslauf aufzunehmen.
Sie sind für die Verwendung mit Gewindeteilen der Zugfestigkeitsklasse 1 100 MPa ) vorgesehen.
Durch die Verkadmung ist der Einsatz auf eine Temperatur von max. 235 °C begrenzt.
