High tensile strength structural steel ASTM A325 heavy hex bolt

1. It is the Standard Specification for High-Strength Bolts For Structural Steel Joints(Metric)

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 specification 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:

Type 1-Bolts made of medium-carbon steel.
Type 2-Bolts made from what is generally described as low-carbon martensite steel.
Type 3-Bolts made of steel having atmospheric corrosion resistance and weathering characteristics comparable to that of the steel covered in specification 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. When properly exposed to the atmosphere, these steels can be used bare(uncoated) for many applications.
