NOTE 2—A complete metric companion to Specification A has been developed—AM; therefore, no metric equivalents are presented in this specification. When A zinc-coated inch series nuts are supplied, the zinc coating, overtapping, lubrication and rotational capacity testing shall be in accordance with Specification A The major and minor diameters shall also be increased by the allowance to provide the corresponding minimum and maximum major and minor diameters.
When properly exposed to the atmosphere, these steels can be used bare uncoated for many applications. The manufacturer shall afford the inspector all reasonable facilities to satisfy him that the material is being furnished in accordance with this specification. When the dimensional style of the nut is not designated by the purchaser, hex nuts, Style 2, in conformance with ANSI B Class 9 nuts marked on one of the wrenching ats shall have the numeral 9 underlined.
