ASTM F2280-11<\/h3>\n

Historical Standard: Standard Specification for \u201c<\/span>Twist Off\u201d<\/span> Type Tension Control Structural Bolt\/Nut\/Washer Assemblies, Steel, Heat Treated, 150 ksi Minimum Tensile Strength<\/h4>\n
\n

ASTM F2280<\/h4>\n

Scope<\/strong><\/p>\n

1.1 This specification covers two types of heat treated, steel, tension control bolt-nut-washer assemblies, also referred to as \u201c<\/span>sets,\u201d<\/span> having a tensile strength of 150 to 173 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.<\/p>\n

1.2 An assembly consists of a tension control bolt with spline end (covered by this specification) and a suitable nut and washer covered by reference to applicable ASTM specifications.<\/p>\n

1.3 The fastener assemblies are intended for use in structural connections. These connections, installation procedures, and the use of alternate design structural bolts are covered under the requirements of the \u201c<\/span>Specification for Structural Joints Using ASTM or A490 Bolts\u201d<\/span>, approved by the Research Council on Structural Connections.<\/p>\n

1.4 The assemblies are available with either round (button or dome) heads, heavy hex structural heads, or alternate design heads described in Section 11 , in sizes \u00bd<\/span> to 1 1<\/sup>\/8<\/sub><\/small> in. inclusive, in two types specified in Section 4.<\/p>\n

1.5 Tension control bolts manufactured and marked in accordance with the requirements of Specification A490, and conforming to the dimensional and other requirements of this specification, will be considered an acceptable alternate under this specification for two years following initial publication.<\/p>\n

1.6 The following precautionary statement pertains only to the test method portions, Sections 15 and 16, 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.<\/span><\/p>\n
