[中文适用范围]： 范围 本国际标准 specifications the dimensions of hexagon slotted (caselated) nuts, reduced height, 600 normal across M Pa/425°C, flats, with MJ 900 M Pa/235 thread sizes, °C, 900 of classifications: M Pa/315°C, 900 450 M Pa/120 M Pa/650°C, °C, 1450 100 M Pa/235 M Pa/235°C, °C, 1100 M Pa/730 ° C, and 1250 M Pa/600 ° C. NOTE 1: 450 M Pa, 600 M Pa, 900 M Pa, 1100 M Pa and 1250 M Pa correspond to the minimum tensile strength NOTE 2: 120 °C, 235 °C, 425 °C, 315 °C, 650 °C, 730 ° C and 600 ° C correspond to the maximum temperature which the nut is able to withstand at ambient temperature without breaking or cracking when tested with a bolt of a higher strength class. 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. 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.
