Standard Specification for Hex Cap Screws, Bolts and Studs, Steel, Heat Treated, 120/105/90 ksi Minimum Tensile Strength, General Use
The following bibliographic material is provided to assist you with your purchasing decision:
This specification2 covers quenched and tempered steel hex cap screws, bolts, and studs having a minimum tensile strength. The fasteners are intended for general engineering use. Type 1 fasteners shall be plain carbon steel, carbon boron steel, alloy steel, or alloy boron steels conforming to the requirements. Type 3 fasteners shall be weathering steel and shall conform to one of the chemical compositions specified. Tensile strength, proof load, hardness tests, and axial tension tests shall be performed to conform with the specified requirements.
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Type 2 | Withdrawn 2003 |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.
