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 exhibited
retracted pins on the type N connectors at both ends. I replaced them with
PL-259's. ... Success anecdotes about install once and never touch again
commercial sites are probably not relevant to ham applications.
