(Specification)Standard Specification for “Twist Off” Type Tension Control Structural Bolt/Nut/Washer Assemblies, Alloy Steel, Heat Treated, 200 ksi Minimum Tensile Strength
Standard Specification for “Twist Off” Type Tension Control Structural Bolt/Nut/Washer Assemblies, Alloy Steel, Heat Treated, 200 ksi Minimum Tensile Strength
SIGNIFICANCE AND USE
A2.4 Significance and Use
A2.4.1 This test method describes the testing procedure that shall be used to qualify material for use in ASTM F3043 bolts made of any steel composition permitted by this specification. The test method measures the susceptibility of the material to the influence of an externally applied potential (see A2.7.2.3.2) by testing for the threshold of embrittlement in a salt solution environment.
SCOPE
1.1 This 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.
1.2 An assembly consists of a tension control bolt with spline end, nut and washer covered by this specification.
1.3 The assemblies are available with round heads described in Section 10, in sizes 1 in. to 11/4 in. inclusive.
1.4 The fastener assemblies are intended for use in structural connections in the following environmental conditions:
1.4.1 Interiors, normally dry, including interiors where structural steel is embedded in concrete, encased in masonry or protected by membrane or noncorrosive contact type fireproofing.
1.4.2 Interiors 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.
1.5 The 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:
1.5.1 Exteriors not under roof.
1.5.2 Chemical 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.
1.5.3 Heavy industrial environments severe enough to be classified as a chemical environment as described in 1.5.2.
1.5.4 Condensation and high humidity environments maintaining almost continuous condensation, including submerged in water and soil.
1.5.5 Cathodically protected environments, in which current is applied to the structural steel system by the sacrificial anode method or the DC power method.
1.6 Units—The values stated in inch-pound units are to be regarded as standard. No other units of measurement are included in this standard.
1.7 The 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 and health practices and determine the applicability of regulatory limitations prior to use.
