Festeelementer til luft- og romfartøy konstruksjoner

ISO 12261:2016 specifies the dimensions of pan head screws with internal offset cruciform ribbed or unribbed drive, pitch diameter shank and long length MJ threads, in metallic material, coated or uncoated, with strength classes less than or equal to 1 100 MPa.

ISO 12261:2016 is applicable to the compilation of aerospace product standards.

This International Standard specifies test methods for metric self-locking nuts with MJ threads intended for use in

aerospace construction at maximum operating temperatures less than or equal to 425 °C. It describes the test

device and the method for each test.

It applies to self-locking nuts as defined above, provided that the relevant documents (dimensional standard,

drawing, procurement specification, etc.) refer to this International Standard.

This International Standard shall be used in conjunction with ISO 5858.

NOTE This International Standard only specifies tests for ambient and elevated temperature applications. Tests for

applications at less than ambient temperatures, for example cryogenic, shall be as agreed upon between seller and purchaser.
