scope:

General

This annex contains additional information concerning the manufacture of countersunk head screws outside Germany.

Owing to varying approving procedures, production methods, materials, etc., the details given in this Standard on countersunk head screws are not always sufficient for manufacture abroad. for instance, materials are used there which may well ensure the required characteristics for a standard part in its final state, but which are not listed as equivalent materials in the relevant data sheet in the German aviation Materials Manual, Part I.

The foreign materials listed in DIN 29+895 (at present at the stage of draft) are approved by the responsible qualification authorities of the individual countries as equivalent to the German material.

The surface treatment specified in clause A.3 is equivalent to that called for in LN 9368 Part 1 and Part 5.
