my colleague Ms Link is out of office at the moment.
The stand: All nuts should have a thread. I’ll send you a replacement for the defective one. The long screws go vertical (top to bottom), the shorter screws go horizontal (left to right).
The stand was sent with parcel service (air), because it’s to heavy to send as postal parcel. That’s why you received it faster.
Have a nice day!
Kind regards,
