ASTM F 3043 : 2015

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:

1.5The 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:

1.6Units—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 and health practices and determine the applicability of regulatory limitations prior to use.
