Aerospace series Shank nuts, serrated, self-locking, in heat resisting steel FE-PA2601 (A286), silver plated on thread Classification: 1 100 MPa (at ambient temperature) / 650 °C
|Publication Date:||31 March 2012|
This standard specifies the characteristics of self-locking serrated shank nuts in FE-PA2601, silver plated on thread, for aerospace applications.
Classification: 1 100 MPa 1) / 650 °C 2).
1) Correspond 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.
