Anyone know how to calculate an impact test exemption for a backing band (Type 2 Joint)? Looking for guidance on determining a required thickness to use in calcs.
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?
