Scope

1.1 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 1¹/₂ in.; and 90 ksi for diameters 1³/₄ in. to 3.0 in. inclusive. The term "fasteners" in this specification denotes hex cap screws, bolts, and studs.

1.2 The fasteners are intended for general engineering use.

1.3 The fasteners are furnished in diameters ¹/₄ to 3.0 in. inclusive. They are designated by type denoting chemical composition as follows:

Type	Description
Type I	Plain carbon steel, carbon boron steel, alloy steel, or alloy boron steel
Type 2	Withdrawn 2003
Type 3	Weathering steel

1.4 Terms used in this specification are defined in Terminology F1789 unless otherwise defined in this specification.

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

1.6 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.
