Aerospace -- Gang channel, self-locking, floating, standard series, with counterbore, classifications: 1 100 MPa (at ambient temperature) / 120 degrees C, 1 100 MPa (at ambient temperature) / 235 degrees C and 1 100 MPa (at ambient temperature) / 425 degrees C -- Dimensions
This International Standard specifies the dimensions of standard series gang channels with self-locking, floating nuts, with counterbore, with MJ threads, of classifications: 1 100 MPa1)/120 °C 2), 1 100 MPa1)/235 °C 2), 1 100 MPa1)/425 °C 2).
This International Standard is only applicable to the compilation of aerospace product standards.
1) Corresponds to the minimum tensile stress which the nut is able to withstand at ambient temperature without breaking or cracking when tested with a bolt of a higher strength class.
2) 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 either by the material or by the surface treatment.
