My few experiences with machined Chinese product I have come to the conclusion they really DONT know how to do it!
I'm sure your fastener should be 6x1. I bet you can almost turn the tap in by hand. Just turn it in a little at a time and make sure it goes in straight.
Not a hard job. 6x1 is the only tap size I have worn out multiple times. Keeping one around will save you headaches later.
Tap it already and be done with it.........
Let's pretend for a second the automatic censoring had a clue...
Yeah, we'll have no more of this, thanks.

Just an addendum in case anyone else runs into this.
All the holes are now tapped and by all appearances, the manufacturer was just using a very worn tap M6 tap. Ours followed the thread but pulled out a good amount of additional material.
But, in the end, no worries. Just one of those quirks that might crop up when getting these off brand frames.
Great it all worked out for you!
If you are thinking bottoming tap, I assume its post mount,
ISO would be fine with a common tapered type tap..
