Crappy Chinese drywall, now crappy Chinese lag bolts!
Like most things Chinese their bolts and other hardware are complete garbage. They may have grade markings on them but that is a joke. If you have to use Chinese lag bolts make the hole about halfway between the recommended drill and the overall stated diameter of the lag bolt. You may even break them then in harder wood. Have I mentioned that they are crap?
When and what was last GOOD QUALITY american product? That could make a trade balance even?
