Standard Specification for Zinc Coating, Hot-Dip, Requirements for Application to Carbon and Alloy Steel Bolts, Screws, Washers, Nuts, and Special Threaded Fasteners [Metric]
This specification covers the requirements for zinc coatings applied by the hot-dip coating technique onto carbon and alloy steel bolts, screws, washers, nuts, and special threaded fasteners that are centrifuged or otherwise handled to remove excess galvanizing bath metal (free zinc). Nails and rivets are not addressed in this specification. Appropriately sampled specimens shall be tested, and conform accordingly to specified requirements for chemical composition, coating thickness, finish and appearance, embrittlement, and adhesion.
1.1 This specification covers the requirements for hot-dip zinc coating applied to carbon steel and alloy steel bolts, screws, washers, nuts, and special threaded fasteners applied by the hot-dip coating process that are manufactured in SI units (metric). Nails and rivets are not included in this specification.
Note 1—This specification is the metric companion of Specification F 2329.
1.2 This specification is intended to be applicable to fasteners that are centrifuged or otherwise handled to remove excess galvanizing bath metal (free zinc).
1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
