If you buy the calcs from UST for $25, you can
read the bolt specs off of those. For my
HDX-5106, they show ASTM A36 or equivalent, 1.125 inch
diameter, 27 inch long, 36,000 psi yield strength.
Note that the HDX-5106 uses 12 anchor bolts,
for which UST charges over $50 each.
Don't know how A193 compares to A36.
