|Publication Date:||1 October 2014|
|ICS Code (Bolts, screws, studs):||21.060.10|
This specification2 covers quenched and tempered steel hex cap screws, bolts, and studs having a minimum tensile strength of 120 ksi for diameters 1.0 in. and smaller; 105 ksi for diameters over 1.0 in. to 1½ in.; and 90 ksi for diameters 1¾ in. to 3.0 in. inclusive. The term "fasteners" in this specification denotes hex cap screws, bolts, and studs.
The fasteners are intended for general engineering use.
The fasteners are furnished in diameters ¼ to 3.0 in. inclusive. They are designated by type denoting chemical composition.
Terms used in this specification are defined in Terminology F1789 unless otherwise defined in this specification.
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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
