Grades | All Thread Rod
30. 45. ASTM A36. ASTM A36 is a steel grade, not a fastener specification. Technically, all thread rod made from A36 steel should be ordered to a fastener specification such as A307 Grade A, A307 Grade B, F1554 Grade 36, or SAE J429 Grade 2. The appropriate fastener specification will depend on the application.
