BS ISO 3209:2016

Aerospace. Nuts, anchor, self-locking, floating, two lug, with counterbore, with MJ threads, classifications: 1 100 MPa (at ambient temperature)/235 °C, 1 100 MPa (at ambient temperature)/315 °C and 1 100 MPa (at ambient temperature)/ 425 °C. Dimensions

1 Scope

This International Standard specifies the dimensions of self-locking, floating, two lug anchor nuts, with counterbore, with MJ threads, of classifications: 1 100 MPa/235 °C, 1 100 MPa/315 °C and 1 100 MPa/425 °C.

NOTE 1 1 100 MPa 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.

NOTE 2 235 °C, 315 °C and 425 °C corresponds to 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 surface treatment.

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