Well here's the advantage of captivated center pins: the pin is NOT
bonded to the center conductor. IOW, if the coax center conductor
shrinks a bit, it can slide in the center pin and the pin stays put.
And that's exactly what you want it to do - especially with an N connector.

Exactly my experience, even with captivated pins!! And my coax runs
were only about 100' long.
The captivating washers were made of Teflon®, *and Teflon cold
flows*. This was when I lived in Toledo, Ohio when the temperature
dropped well below zero.
Four photos of those N connectors are at

My two 500 foot RG-216 military surplus cables both eventually

relevant to ham applications.
