How to mount BLDC motor, since stator doesn't appear to have countersunk openings

Regarding this motor:

As I said, in the title, I’m confused how to use the M1.6 mounting holes if they’re not countersunk. I’m trying to replicate similar functionality found in this project (from the exploded diagram animation it does not appear to use the M1.6 holes at all, but the motor mount in the project has holes that mirror those of the motor’s):

Any advice is greatly appreciated.

Threadlocker + bolts

Our version looks like this

Oh! You mean you’ve basically glued it into the motor with threadlocker?

Also, I just noticed that the motor is now backordered and has gone up nearly 50% in price (thank you tariffs, I assume). Will it be back in stock in the foreseeable future?
