Abstract
This specification covers carbon steel track bolts and carbon steel nuts for use in conjunction with joint bars to connect rails in railroad track. 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 Two grades of track bolts are defined:
1.2.1 Grade 1, Low-Carbon, Untreated, primarily for industrial and mine track use.
1.2.2 Grade 2, Heat-Treated, for general track use.
1.3 Two grades of nuts are defined:
1.3.1 Grade 1, Low-Carbonor Soft Steel, primarily for application on Grade 1 track bolts.
1.3.2 Grade 2, Medium-Carbon, 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.
Domestic orders are delivered via United Parcel Service (UPS) or United States Postal Service (USPS). Transit
times average 3 to 5 business days. Please be aware that UPS will not deliver packages to Post Office Boxes.
International orders are delivered via courier post services which can be either a postal service, courier
service, or a combination of both. Standard Service is untraceable. Please allow 4-7 weeks for delivery.
Please be aware that carriers will not deliver packages to Post Office Boxes. Because of the variability of
customs processes and procedures in different countries, ASTM International cannot guarantee transit times to
international destinations. Customs duty and taxes are the responsibility of the consignee.
