I just received my Gladiator NXT EVO, the product looks and smells good, as expected

So I set it up using the YT tutorial and, while tightening the screw on the X-axis dry clutch, nothing changes.
The Y-axis dampens as expected though, so I decide to take the unit apart.
On the first picture, it seems that a screw is missing (red arrow) to secure the clutch.
I took a higher resolution picture to show that the hole is new and hasn't been threaded yet.
That would explain my problem and the product being new, I thought I'd ask before attempting anything else.
The base comes with an extra set of screws that are not covered in the tutorial, should I use them? It's not going to explode, is it?
Regards,
