Published By:British Standards Institution (BSI)
This standard specifies the characteristics of self-locking bihexagonal nuts in FE-PA92HT, silver plated, for aerospace applications.
Classification: 1 100 MPa1)/650 °C2)
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 test temperature of the parts
