thread507-346292: High tensile bolts circa mid-1950s
This is continuation of the above thread, which has been closed.
I've attached a picture of some bolts used in a steel building from the 1950s. The plans call for 3/4" diameter "high tensile" bolts, which I've figured out was an early term for ASTM A325 bolts.
Can anyone verify? Just want to be sure, because it is critical at certain connections.
