This standard specifies the characteristics; qualification and acceptance requirements for self-locking nuts with MJ threads in NI-PH2601, silver plated, for aerospace applications.
Classification: 1 550 MPa / 600 ℃
It is applicable whenever referenced.
note: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
