I don’t think you need to worry about sizes (or pitch) everything I have gotten from them has been correct but material and strength (temper) are definitely something to be wary of. So yea if you need ansi strength out of a bolt don’t get it from Amazon, but if you are just using a 1/4"-20 to fasten something together you’re probably fine.
