Probably not at HD since they were 316. Get them from Mcmaster. We used wedge anchor bolts. Go about 1.5" deep in the concrete and YES let it cure at LEAST a month before using them. Concrete will achieve most of its strength after 28 days, but the longer, the better. You could also just epoxy in 316 SS threaded rod if you wanted.
3" is pushing it, but it'd probably seal. Are you having a top brace on the acrylic, or just having the acrylic as the top edge? Cant remember by page 7 You will need a thick piece to avoid deflection over 10'!
One more thing about using acrylic vs glass... If your window pillar pour is off plane by a tad, acrylic will better "absorb" that flaw than glass.
