Heat analysis Product analysis Nickel: Selection of steel analysis shall be the option of the manufacturer. NOTE 1—Throughout this specication, the term class means property class.
However, if markings are located on the bearing surface, they shall be depressed. Current edition approved April 1, Individual heats of steel are not identified in the finished product.
Nominal Nut Size, in. Heat analysis Product analysis Sulfur: Individual reprints single or multiple copies of this standard may be obtained by contacting ASTM at the above address or at phonefaxor service astm. Slotted hex nuts are not normally proof load tested. A number in parentheses indicates the year of last reapproval. This shall be the only hardness requirement for nuts that are proof load tested. When the dimensional style of nut is not designated by the purchaser, hex nuts, Style 1, in conformance with ANSI B Others are not suitable.

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.
Heavy Hexagon Nuts ASTM AM
NOTE 2— Proof loads are computed by multiplying proof load stress Table 3 by thread stress area and dividing by Number of Tests 9. When properly exposed to the atmosphere, these steels can be used bare uncoated for many applications.

Plain Uncoated Nuts 7. Heat analysis Product analysis Phosphorus: Purchasers are cautioned to consider the dimensional requirements of the application when selecting the most appropriate nut. Heat analysis Product analysis Sulfur: Classes 8S3 and 10S3 nuts have atmospheric corrosion resistance and weathering characteristics comparable to those of the steels.
When properly exposed to the atmosphere, these steels can be used bare uncoated for many applications. B Non-zinc-coated nuts are nuts intended for use with externally threaded fasteners which have a plain nonplated or noncoated finish or have a plating or coating of insufficient thickness to necessitate overtapping the nut thread to provide assemblability.
C3 nuts may be made of any of the above listed material classes.
Nickel or molybdenum may be used. E Non-zinc-coated nuts are nuts intended for use with externally threaded fasteners, which have a plain nonplated or noncoated finish or a have a plating or coating of insufficient thickness to necessitate overtapping the nut thread to provide assembiability. NOTE 4—Purchasers are cautioned that different classes of nuts have different nut thickness see 7.
