Hello Structural Engineers - I'm an ME in need of guidance.
I am curious as to your interpertation of a Drawing that reads 'Grade 5 or Better' (in particular the Grade 5 ref. in a structural steel connection) for structural bolts. Without any other information, would you assume that means..
to have the material and mechanical qualities of:
SAE J-429 Grade 5 bolts?
If so - why do people use the SAE reference now-a-days when the ASTM seems to be the standard for construction in the US. Something historical perhaps? International?
Thanks!
