ASTM AM – 07() Standard Specification for Carbon and Alloy Steel Nuts (Metric)
The manufacturer shall afford the inspector all reasonable facilities to satisfy him a653m the material is being furnished in accordance with this specification.
In addition, the manufacturer may add other distinguishing marks indicating that the nut is atmospheric corrosion resistant and of a weathering type.
This standard is subject to revision at any time by the responsible a5563m committee and must be reviewed every five years and if not revised, either reapproved or withdrawn.
Specification F, or otherwise hot-dip coated, shall be tapped oversize by a diametral amount sufficient to permit assembly on the coated bolt thread, unless other requirements are specified in the inquiry or purchase order.
Classes 8S3 and 10S3 nuts have atmospheric corrosion resistance and weathering characteristics comparable to those of the steels. A, B, D, Zstm Rejection and Rehearing A number astk parentheses indicates the year of last reapproval. When individual marking is required, the mark shall be the grade letter symbol on one face of the nut. Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters.
See Guide G for methods of estimating the atmospheric corrosion resistance asfm low alloy steels. Hex nuts made to the requirements of DH3 shall be marked with the symbol HX3 on one face.

Note 1 — Throughout this specification, the term class means property class. If you feel that your comments have not received a fair hearing you should make your w563m known to the ASTM Committee on Standards, at the address shown below. Originally approved in We are a non-profit group that run this website to share documents. Please help us to share our service with your friends. When properly exposed to the atmosphere, these steels can be used bare uncoated for many applications.
Thank you for interesting in our services. Selection of the class shall be at the option of the manufacturer. Such nuts are suitable. 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.
