1.1This specification covers one style of heat treated, alloy steel, tension control bolt-nut-washer assemblies, also referred to as “sets,” having a tensile strength of 200 to 215 ksi. These assemblies are capable of developing a minimum predetermined tension when installed by applying torque to the nut, while at the same time applying a counter torque to separate the spline end from the body of the bolt using an appropriate spline drive installation tool.
1.2An assembly consists of a tension control bolt with spline end, nut and washer covered by this specification.
1.3The assemblies are available with round heads described in Section 10, in sizes 1 in. to 11/4in. inclusive.
1.4The fastener assemblies are intended for use in structural connections in the following environmental conditions:
1.4.1Interiors, normally dry, including interiors where structural steel is embedded in concrete, encased in masonry or protected by membrane or noncorrosive contact type fireproofing.
1.4.2Interiors and exteriors, normally dry, under roof, where the installed assemblies are soundly protected by a shop-applied or field-applied coating to the structural steel system.
1.5The fastener assemblies are not intended for use in structural connections in the following environments, with or without protection by a shop-applied or field-applied coating to the structural steel system:
1.5.1Exteriors not under roof.
1.5.2Chemical environments in which strong concentrations of highly corrosive gases, fumes, or chemicals, either in solution or as concentrated liquids or solids, contact the fasteners or their protective coating.
1.5.3Heavy industrial environments severe enough to be classified as a chemical environment as described in 1.5.2.
1.5.4Condensation and high humidity environments maintaining almost continuous condensation, including submerged in water and soil.
1.5.5Cathodically protected environments, in which current is applied to the structural steel system by the sacrificial anode method or the DC power method.
1.6Units—The values stated in inch-pound units are to be regarded as standard. No other units of measurement are included in this standard.
1.7The following precautionary statement pertains only to the test method portions, Section 13, Section 14 and Annex A2 of this Specification: 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.
1.8This 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.
