* 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, or F1554 Grade 36. The appropriate fastener specification will depend on the application. However, Portland Bolt stocks all thread rod manufactured from A36 steel and can certify it as such upon request. Learn more about ordering fasteners to A36 in this FAQ. |
