Bolt Specs - Grade 5 vs. SA-449

[syagla]

Bolt markings are identical for SAE J429 Grade 5 and ASTM A449 Type 1. Are these specifications identical? In other words, if I buy a "Grade 5" bolt, am I automatically getting a bolt that conforms to ASTM A449?

Based on the Machinery’s Handbook 26 (pg 1488) it seems to be identical.

Ans.-Maybe If you are looking for an SA bolt you should have a copy of ASME SecII Part A,look up SA-449.
