1.1 This specification covers two types of heat treated, steel, tension control bolt-nut-washer assemblies, also referred to as sets. 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 (covered by this specification) and a suitable nut and washer covered by reference to applicable ASTM specifications.

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 Specification for Structural Joints Using ASTM A 325 or A 490 Bolts, approved by the Research Council on Structural Connection.

1.4 The assemblies are available with either round (button or dome) heads, heavy hex structural heads, or alternate design heads described in Section 10 and Fig. 1, in sizes ½ to 1 1/8 in. inclusive, in two types specified in Section 4.

1.5 Terms used in this specification are defined in Terminology F 1789 unless otherwise defined herein.

1.6 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, Sections 13 and 14, 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.

This specification covers two types of heat treated, steel, tension control bolt-nut washer assemblies. An assembly consists of a tension control bolt with spline end and a suitable nut and washer. 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. The fastener assemblies are intended for use in structural connections. The tension control bolts are designed by type denoting chemical composition as follows: Type 1Plain carbon, carbon boron, or alloy steel; and Type 3Weathering steel. Materials shall be tested using assembly lot tension test, and the individual grades shall conform to materials requirements such as heat treatment, thread, mechanical zinc coating, lubrication, and secondary processing; chemical composition, mechanical property requirements for tension control bolts such as hardness (Brinell and Rockwell C), tensile strength, and yield strength. Workmanship, finish and appearance; and head burst visual inspection are also detailed.
