Each and every one of you after my original reply to that question, are correct...
There are the applications, need and end results.
Each one of these replies is correct.
The only area I was trying and hopefully have addressed, is when you have coax, and need to make a connector- the question was just that - only I added the ability for the connector to work as a temporary or if soldered - permanent replacement.
But only if the application warranted it, so I left that to the OP - I see a photo I recognized and responded as yes, and here's how I do it...
Side benefit of the threaded is the ability to have it taken apart to allow you to keep the coaxial small diameter to thread thru knockouts holes and grommets without having to lose a connector each time you have to cut off the end - it also allows you to remove the coax without losing the ability to re-make the coax with a new connector for the next temporary install.
I didn't want to overthink the problem - at least from a vehicle owners perspective. Anyone whom has had to route coax thru firewalls, brackets, bracing, headliners and the like - can appreciate the ability to keep the threaded coax and thread it on when done and even then, you can remove the threaded and sleeve w/solder only if it's required to be more permanent as needed.
