The required chemical composition for steel is presented in details. The full section and the reduced-section bolt tension tests requirements are specified as per reference materials.
SCOPE
1.1 This specification covers carbon steel track bolts and carbon steel nuts for use in conjunction with joint bars to connect rails in railroad track.  
1.2 Heat-treated bolts for general track use.  
1.3 Medium carbon nuts for general application on track bolts.  
1.4 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
