HELP WITH BOLTS ASTM - A-563 GR. A OR B

[JOHN1978]

Greetings from Peru.

Hi, my name is John Altamirano; I am Mechanical Engineer.
I have a problem and it's about Bolts.

I need some help.
I have to buy Hexagonal Bolts ASTM A-563 Grade A (5/8", 3/4", 1") and Grade B (1/2").
After looking at the local market. I found there aren't Bolts with those features.

I would like to know if there are equivalents to those bolts for buying them instead the first ones
because I just need few pieces of these. And I am not thinking to buy them abroad.
I thanks anyone who can help to solve my problem.
And I will appreciate if you can answer my question as soon as it can be.

You will need to look at a different specification for the bolts as the A 563 spec is for nuts only.
Use A 325 or A 449 for structural bolts.

Need to correct my prvious post!
The bolts should be:
ASTM A 325 or A 490
Both should be bought as a set bolt and nut.
