适用范围

This International Standard specifies the dimensions of hexagon slotted (castellated) nuts, reduced height, normal across flats, with MJ threads, of classifications: 450MPa/120℃, 450 MPa/235℃, 600 MPa/425 ℃, 900 MPa/235 ℃, 900 MPa/315℃, 900 MPa/650℃, 1 100 MPa/235 ℃, 1 100 MPa/730 ℃, and 1 250MPa/600℃. These nuts are intended to be used with split pins in conformity with ISO 1234. This International Standard is applicable for the compilation of aerospace product standards. note: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 by the material or by the surface treatment. 3) To be published. (Revision of ISO 1234:1976)
