Don’t know about 12V but all the high voltage connectors when converting a car to electric drive get crimped and if screwed in a plug a crimped sleeve gets added.
Thought I had answered, and managed to destroy my good crimpers.
You don't count, as you know what your doing. Have seen some really poor crimped connectors. The kind you buy at the cheap place with a cheap tool that leaves a crimped connecter that can easily pulled off.
