ASTM A325M-00

Standard Specification for High-Strength Bolts for Structural Steel Joints [Metric]

SCOPE
1.1 This specification  covers requirements of various types of quenched and tempered steel bolts in nominal thread diameters M16 to M36 inclusive, commonly known as "high-strength structural bolts," intended for use in structural joints that are comparable to those made under the Specifications for Structural Joints Using ASTM A325 or A490 Bolts,  issued by the Research Council on Structural Connections of the Engineering Foundation. Types of bolts covered in this specification are:  
1.1.1 Type 1 -Bolts made of medium-carbon steel.  
1.1.2 Type 2 -Bolts made from what is generally described as low-carbon martensite steel.  
1.1.3 Type 3 -Bolts made of steel having atmospheric corrosion resistance and weathering characteristics comparable to that of the steel covered in Specifications A588/ A588M, A242/A242M, and A709/A709M. The atmospheric corrosion resistance of these steels is substantially better than that of carbon steel with or without copper addition (see 5.3). When properly exposed to the atmosphere, these steels can be used bare (uncoated) for many applications.
1.2 This specification provides that heavy hex structural bolts shall be furnished unless other dimensional requirements are stipulated in the purchase inquiry and order.  
1.3 Unless otherwise specified, all nuts used on these bolts shall conform to the requirements of Specification A563M shall be heavy hex, and shall be of the class and surface finish for each type of bolt as follows:  Bolt Type and Finish Nut Class and Finish 1 and 2, plain (noncoated) 8S or 8S3, plain 1 and 2, zinc-coated 10S, zinc-coated 3, plain 8S3, plain
1.4 Unless otherwise specified, all washers used on these bolts shall conform to the requirements of Specification F436M and shall be of a surface finish for each type of bolt as follows: Bolt Type and Finish Washer Finish 1 and 2, plain (uncoated) plain (uncoated) 1 and 2, zinc-coated 3, plain weathering steel, plain
1.5 Zinc-coated bolts and nuts shall be shipped in the same container.
