Packaging and Package Marking Your comments will receive careful a563j at a meeting of the responsible technical committee, which you may attend.

NOTE 2— Proof loads are computed by multiplying proof load stress Table 3 by thread stress area and dividing by Nuts With Other Coatings 7.

Committee F16 has identified the location of selected changes made to this standard since the last issue, A—04a, that may impact the use of this a5663m. Markings located on the top or bearing surface or on the top of the ange shall be positioned with the base of the numeral s oriented toward the nut periphery.

This shall be the only hardness requirement for nuts that are proof load tested. 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. Nickel or molybdenum may be used. Such nuts shall be tapped oversize to have internal threads with maximum and minimum limits that exceed the maximum and a536m limits specied for metric coarse internal threads with Grade 6H tolerances by the following diametral allowances: Rejection should be reported to the producer or supplier promptly and in writing.

Heavy Hexagon Nuts ASTM AM

The atmospheric corrosion resistance of these steels is substantially better than that of carbon steel with or without copper addition see 5. A number in parentheses indicates the year of last reapproval.

Note 1 — Throughout this specification, the term class means property class.

Heat analysis Product analysis Copper: Selection of steel analysis shall be the option of the manufacturer. In case of dissatisfaction with the results of the test, the producer or supplier may make claim for a rehearing. 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 Classes 8S3 and 10S3 nuts have atmospheric corrosion resistance and weathering characteristics comparable to those of the steels.

ASTM International takes no position respecting the validity of any patent rights asserted in connection with any item mentioned in this standard. Note 3 — This specification is the metric companion of Specification A NOTE 7—The proof load of a nut is the axially applied load the nut must withstand without thread stripping or rupture.
