Class 12 nuts in nominal thread diameters M42 and larger shall conform to dimensions for heavy hex nuts given in ANSI B The manufacturer shall afford the inspector all a563 facilities to satisfy him that the material is being furnished in accordance with this specification.

Originally approved in When properly exposed to the atmosphere, these steels can be used bare uncoated for many applications.

Asrm 9—If the over-tapping diametral allowance is greater than the limit specied in 7. Note 3 — This specification is the metric companion of Specification A Heat analysis Product analysis Titanium: Heat analysis Product analysis Manganese: Packaging and Package Marking Heat analysis Product analysis Nickel: 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 4—Purchasers are cautioned that different classes of nuts have different nut thickness see 7. Additional tests of individual shipments of material are not ordinarily contemplated.

ASTM A563M

Hex nuts made to the requirements of DH3 shall a563n marked with the symbol HX3 on one face. 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. The atmospheric corrosion resistance of these steels is substantially better than that of carbon steel with or without copper addition see 5.
