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:
| Grade | Nominal Size | Proof Load Min (ksi) | Yield Strength Min (ksi) | Tensile Strength Min (ksi) | Rockwell Hardness Min | Rockwell Hardness Max |
| ASTM A325-1 | 1/2" - 1" | 85 | 92 | 120 | C24 | C35 |
| 1-1/8" - 1-1/2" | 74 | 81 | 105 | C19 | C31 | |
| SAE J429 Grade 8 | 1/4" - 1-1/2" | 120 | 130 | 150 | C33 | C39 |
