Annotation

General

This annex contains additional information for the manufacture of pan head bolts outside Germany.

Owing to varying approving procedures, production methods, materials, etc. the details given in this standard on pan head bolts, cross recessed, are not always sufficient for manufacture abroad. For instance, materials are used which may well ensure the required characteristics for a standard part in its final state, but which are not listed as equivalent material in the corresponding data sheet of the German Aviation Materials Manual, Part I.

The foreign materials listed in DIN 29895 (at present in draft form) are approved by the responsible qualification authorities of the individual countries as equivalent to the German material.

The surface treatment required in Clause A.3 is equivalent to that called for by LN 9368 Parts 1 and 5.

A.2 Materials

For alternative materials see DIN 29895 (at present in draft form).
