I realize that you're just trying to help, but this is horrible advice. That's guaranteeing cheap Chinese **** hardware that's going to be subgrade at best.
OP, contact a fastener store where someone can GUARANTEE country of origin, or order them from McMaster Carr (you still need to verify country of origin which is in the product details on their site).
I check threads every day and most Chinese fasteners barely fit, let alone carry critical load.
