Defines the dimensions of floating, self-aligning, two lug anchor nuts, with MJ threads and a self-locking feature achieved by forming the upper portion out-of-round, of the following classifications: - 900 MPa/235 degrees C; - 900 MPa/315 degrees C; - 900 MPa/425 degrees C.

This International Standard specifies the dimensions of floating, self-aligning, two lug anchor nuts, with MJ threads and a self-locking feature achieved by forming the upper portion out-of-round, of the following classifications:

  • 900MPa/235°C;

  • 900MPa/315°C;

  • 900MPa/425°C.

NOTE1 The first element in the classifications (900MPa) corresponds to the minimum tensile stress that the nut is able to withstand at ambient temperature without breaking or cracking when tested with a bolt of a higher strength class.

NOTE2 The second element in the classifications is the maximum temperature that the nut is able to withstand, without permanent alteration to its original characteristics, after ambient temperature has been restored. The maximum temperature is conditioned by the material or by the surface treatment.

This International Standard is only applicable for the compilation of aerospace product standards.
