E Non-zinc-coated nuts are nuts intended for use with externally threaded fasteners, which have a plain nonplated or noncoated finish or a have a plating or coating of insufficient thickness to necessitate overtapping the nut thread to provide assembiability. Please help us to share our service with your friends. Work Item s – proposed revisions of this standard.
When this heat treatment is used, there shall be particular attention to the requirements in 6. Plain Uncoated Nuts 7. Such nuts are suitable. Current edition approved April 1, Individual heats of steel are not identified in the finished product.
Please fill this form, we will try to respond as soon as possible. The lubricant shall be applied to specified surfaces on the nuts, such as 1 principally only those portions which are threaded, or 2 on threaded portions and either only one bearing face or both bearing faces, as required, astmm 3 such other specific lubricant placement criteria as are agreed to between the purchaser and the user.

Committee F16 has identified the location of selected changes to this standard since the last issue A—07 atm may impact the use of this standard. When individual asm is required, the mark shall be the grade letter symbol on one face of the nut.
When properly exposed to the atmosphere, these steels can be used bare uncoated for many applications.
NOTE 2—A complete metric companion to Specification A has been developed—AM; therefore, no metric a563, are presented in this specification. Heat analysis Product analysis Sulfur: Zinc-coated nuts are nuts intended for use with externally threaded fasteners 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.
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 astmm requirements are specified in the inquiry or purchase order.
Details of these supplementary requirements shall be agreed upon in writing between the manufacturer and purchaser.
