It looks like older Buddy v0.1.4, on the GitHub was released Buddy v1.0.0.
The LCD uses quite common ST7789v driver according to Buddy firmware - nothing special.

The screws (bed to spacer) are 3Mx3. They are also low profile countersunk Torx heads. If you were to replace them with 3Mx3 countersunk Hex, they will sit proud of the heatbed.
