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
screws with TORQ-SET recess 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,
The foreign materials listed in DIN 29 895 (at present still in
draft from) are approved by the responsible qualification
authorities as equivalent to the German material.
The surface treatment required in clause A. 3 is equivalent to
the called for by LN 9368 Parts 1 and 5.
Alternative materials see DIN 29 895 (at present still in draft
