What is the point of CNC machined screws? I have only seen that type of thing on specialized military applications and the like.

I'm sure standard rolled screws would be just fine...

If I had to guess, they had easier access to a CNC or someone with CNC skills vs a shop that could get them rolled screws in the right size within their timeframe.

The 'nice' thing about CNC screws is that it's cheaper to do short runs. (which, on the military side, can help on some 'security by obscurity' lengths for revers engineering).

That said Rolled screws are almost always gonna be better unless the die is fucked.
