This standard specifies the characteristics of self-locking serrated shank nuts in FE-PA2601, for aerospace applications.
Classification: 1 100 MPa *) / 650 °C **)
NOTE FE-PA2601 is the new designation for FE-PA92HT, see TR 3900.
*) 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
**) Maximum test temperature of the parts
