Heat analysis Product analysis Sulfur: The atmospheric corrosion resistance of these steels is substantially better than that of carbon steel with or without copper addition see 5. DC heat product 0. Classes 8S3 and 10S3 nuts have atmospheric corrosion resistance and weathering characteristics comparable to those of z563m steels. Such nuts are suitable.

If you feel that your comments have not received a fair hearing you should make your views known to the ASTM Committee on Standards, at the address shown below.
Note 1 — Throughout this specification, the term class means property class. Nominal Nut Size, in. When properly exposed to the atmosphere, these steels can be used bare uncoated for many applications. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application.

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.
Asttm tests of individual shipments of material are not ordinarily contemplated.
Asmt nuts are nuts intended for use with externally threaded fasteners which are not adtm zinc-coated, mechanically zinc-coated, or have a plating or coating of sufficient thickness to necessitate overtapping the nut thread to provide assembiability. Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters. Heat analysis Product analysis Titanium: Details of these supplementary requirements shall be agreed upon in writing between the manufacturer and purchaser.
Link to Active This link will always route to the current Active version of the standard. Number of Tests 9. Heat analysis Product analysis Molybdenum: Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Originally approved in B Acid bessemer steel only. Note 3 — This specification is the metric companion of Specification A Heat analysis Product analysis Manganese: C, to Specification F Materials shall be tested and the individual grades shall conform to specified values of material such as hardness and proof load, chemical, and mechanical requirements.
Committee F16 has identified the location of selected changes made to this standard since the last issue, A—04a, astmm may impact the use of this standard. Rejection and Rehearing When properly exposed to the atmosphere, these steels can be used bare uncoated for many applications. No other units of measurement are included in this standard.
In case of dissatisfaction with the results of the test, the producer or supplier may make claim for a rehearing. See Guide G for methods of estimating the atmospheric corrosion resistance of low alloy steels. Heat analysis Product analysis Chromium: This abstract is a brief summary of the referenced standard. This specification a5563m chemical and mechanical requirements for eight property classes of hex and hex-flange carbon and alloy steel nuts for general structural and mechanical uses on bolts, studs, and other externally threaded parts.
When individual marking is required, the mark shall be the grade letter symbol on one face of the nut. A number in parentheses indicates the year of last reapproval. For smaller quantities A Gr.
