This standard 21/30445592 DC BS EN 2882. Aerospace series. Nuts, hexagonal, self-locking, with counterbore and captive washer, in steel, cadmium plated, MoS2 lubricated. Classification: 1 100 MPa (at ambient temperature) / 235 °C is classified in these ICS categories:
- 49.030.30 Nuts
This document specifies the characteristics for hexagon nuts, with counterbore and captive washer, with a self-locking feature achieved by forming the upper portion out-of-round, in steel, cadmium plated, MoS2 lubricated, classification 1 100 MPa 1
1
Corresponds to strength class of the associated bolt, the 100 % load of which it is able to withstand, when tested at ambient temperature, without breaking or cracking.
2
Maximum temperature that the nut is able to withstand, without permanent alteration of its original characteristics, after ambient temperature has been restored. The maximum temperature is conditioned by the cadmium plating.
