Were it me, I'd purchase "J-Bolts" of at least grade 5. Of course the best bet is to have an engineering study done, or just calculate the loads to see just what the stress will be on the bolts at th

It seems to me that the strength of the concrete limits the safe load you can put on anchor bolts to a low enough value that ordinary steel is good enough for the bolts. Rick N6RK __________________

I was chatting with a structural guy a few months ago about things like chemical anchors for patio covers and the like (a low load application). Turns out that "taint necessarily so". The problem isn
They literally cannot afford to do any process controls or inspections. On a job in mainland China about 10 years ago a load of structural steel was being brought into the building on a forklift. The
Gentlemen, many thanks for your kind assistance. Frankly, the range of advice ranged from common steel is satisfactory to high strength steel (grade 5 or the like) would be safer. I also talked to an
