ASTM Launches A New Standard Specification for Carbon and Alloy Steel Bolts

ASTM International has announced a new ASTM F2329-11 standard specification for zinc coating, hot dip, requirements for application to carbon and alloy steel bolts, screws, washers, nuts and special threaded fasteners.
 
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. The zinc used for the coating shall conform to the chemical composition required. The following tests shall be made to ensure that the zinc coating is being furnished in accordance with this specification: coating thickness; finish and appearance; embrittlement test and adhesion test.
 
It is intended to be applicable to fasteners that are centrifuged or otherwise handled to remove excess galvanizing bath metal (free zinc).

The values stated in inch pound units are to be regarded as standard. No other units of measurement are included in this standard.
 
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.
