These are for niche needs. For most applications neither is necessary. If needed and space is constrained the single pin variant allows additional connectors to be packed together on a single PCB. The dual pin option doesn’t, it takes up space that could be used for additional connectors.
It looks exactly like what I imagined by screw-lock USB connector, but the single pin seems to be a really inspired design somebody had and made the entire committee angry for some reason.
The single pin only resists force. Two pins resist torques being applied to the usb connector. The single pin does resist torque but it uses the connector potentially damaging the PCB.
Cant do it, the BNC connector is not large enough to house a USBc end, even the Apple one which is the smallest I have. I would have to enlarge the BNC to a near comical size. Now if we removed the moulded housing it could be done, but it would have to be made on a bare PCB/Cable/Connector to be the right size.
I would want an RJ45 charger.
USB-C has official specifications for a screw lock connector
Nice
Why are technical drawings so much cooler?
Because engieneering is so much cooler.
Why two different and incompatible options?
Or, more generally, why can’t I ever read some USB spec and get out with less questions than I had in the beginning?
Because for some reason, the USBIF has been hit over and over again with the stupid stick ever since USB2 came out.

I se no advantage at all for the dual pin design.

Short version: looks good, functions bad
Because USB is pretty much neither universal or standardized, just the same shape and somewhat compatible
The single screw version looks wrong somehow.
I wish things actually used this, it looks really stable.
Well, you can buy them: https://www.coolgear.com/product/usb31-type-c-to-c-dual-screw-lock-cable
That’s cool, but I wouldn’t have anything to attach it to. It would be great if my laptop had those ports though.
You usually do not want connectors to be too stable.
The fact that it unplugs before any part breaking or pushing your devices away is almost always a feature, not a bug.
Coaxial for me
25pin serial cable and ain’t nobody at work gonna steal my phone charger no more.

An N connector should be just big enough, if not, use a 7/16 DIN connector then.
N connector to SMA, and hardline to USB-C.

I have not done a test print yet, but this might work. Requires a Apple USB-C cable because anything else is too big.
Jack or Plug? if plug, would you want it to look like its plugged in, so just the retention tab and back half are sticking out?
It would be epic if it is both.
