All we ever had through our shop was the I beam rods.
I really wish I had taken a picture of the one that we found with the flaw in it.
After we saw that it was not a brand that we were to interested in using anyway.
I have one customer that brings new H beam rods with no bolts in them and a card of new ARP bolts for us to use in the rods, we check them, build them and send him on his merry way.
He has used multiple sets of rods that come without the bolts, not sure where he is getting them, not even sure I want to know!
