Aerospace series - Bolts, double hexagon head, close tolerance, medium thread length, in heat resisting steel FE-PM38 (FV535), uncoated - Classification: 1 000 MPa/550 °C

This standard specifies the dimensions of the uncoated double hexagon head bolts, close tolerance, with MJ-thread, medium thread length, in heat resisting steel FE-PM38 for aerospace applications.
Maximum test temperature of the parts is 550 °C.
These bolts are to be used in aerospace fastening systems mainly stressed in shearing force.

Luft-und Raumfahrt - Zwölftkant-Passschrauben, mittlere Gewindelänge, aus hochwarmfestem Stahl FE-PM38 (FV535), blank - Klasse: 1 000 MPa/550 °C

Diese Norm legt die Maße von blanken Zwölfkant-Passschrauben mit MJ Gewinde, mittlerer Gewindelänge, aus hochwarmfesten Stahl FE PM38 für die Verwendung in der Luft- und Raumfahrt fest.
Die maximale Prüftemperatur der Teile beträgt 550 °C.
Diese Schrauben sind in Verbindungssystemen der Luft- und Raumfahrt zu verwenden, die hauptsächlich auf Scherkraft beansprucht werden.
