ASTM A563M

Heat analysis Product analysis Vanadium: Selection of steel analysis shall be the option of the manufacturer. NOTE 4—Purchasers are cautioned that different classes of nuts have different nut thickness see 7.

When this heat treatment is used, there shall be particular attention to the requirements in 6. The manufacturer shall afford the inspector all reasonable facilities to satisfy him that the material is being furnished in accordance with this specification.

Originally approved in However, if markings are located on the bearing surface or on one of the wrenching ats, they shall be depressed. When required, they are covered by the applicable bolt specification. This standard is subject to revision at any time by the responsible technical committee and must be reviewed every five years and if not revised, either reapproved or withdrawn.

Heat analysis Product w563m Nickel: With the written approval of the purchaser, the supplier may substitute as follows: A superscript epsilon e indicates an editorial change since the last revision or reapproval. This shall be the only hardness requirement for nuts that are proof load tested. A number in parentheses indicates the year of last reapproval.

In case of dissatisfaction with the results of the test, the producer or supplier may make claim for a rehearing. Zinc-coated nuts are nuts intended for use with externally threaded a653m which are not hot-dip zinc-coated, mechanically zinc-coated, or have a plating or coating of sufficient thickness to necessitate overtapping the nut thread to provide assembiability.

Thank you for interesting in our services. Historical Version s – view previous versions of standard. If you feel that your a563j have not received a fair hearing you should make your views known to the ASTM Committee on Standards, at the address shown below.

Additional tests of individual shipments of material are not ordinarily contemplated.

In addition, the manufacturer may add other distinguishing marks indicating that the nut is atmospheric corrosion resistant and of a weathering type.

Note 1 — Throughout this specification, the term class means property class. Specification F, or otherwise hot-dip coated, shall be tapped oversize by a diametral axtm sufficient to permit assembly on the coated bolt thread, unless other requirements are specified in the inquiry or purchase order. Heat analysis Product analysis Chromium: Such nuts shall be tapped oversize to have internal threads with maximum and minimum limits that exceed the maximum and minimum limits specied for metric coarse internal threads with Asym 6H tolerances by the following diametral allowances:
