The manufacturer shall afford the inspector all reasonable facilities to satisfy him that the material is being furnished in accordance with this specification. Users of this standard are expressly advised that determination a563 the validity of any such patent rights, and the risk of infringement of such rights, are entirely their own responsibility.

Class 12 nuts in nominal thread diameters M42 and larger shall conform to dimensions for heavy hex nuts given in ANSI B Number of Tests 9. Zinc-coated nuts are nuts intended for use with externally threaded fasteners which are hot-dip zinc-coated, mechanically z563m, or have a plating or coating of sufficient thickness to necessitate overtapping the nut thread to provide assemblability.

This standard has been approved for use by agencies of the Department of Defense. When individual marking is required, the mark shall be the grade letter symbol on one face of the nut.
