Why use any excessive force on a knurled nut if it is not necessary. Yes, it is
necessary for the PL-256 to ensure a reliable (sort of) connection. (That's why
I don't like it.) You should not expect some repeated twisting motion on the
connector unless it is a too short cable between your tower and your beam.
The rubber gaskets in the N and BNC connectors are mostly for weather sealing
and only a very limited strain release. That's why you find additional release
on military installations. Also you should consider the mechanical connection
on the PL-256 as a more than limited strain release. Yeas, it might be stronger
but that strong.

Use a thin sheet of Silicone rubber in a "U" shape inside the pliers to
protect the connectors. It works for me, but I'm often too impatient to worry
about a cheap PL-259 (Even Silver plated Amphenols are cheap) BNCs are
basically miniature N connectors, bur they lose a lot to scale and are
veryweak. I've never seen them used outdoors. It tales little strength to
pull the coax out of one, making them an interconnect only for me.
N are stronger, but not as strong as a properly soldered UHF connector. They
weather proof, but don't ignore the Coax seal and tape. The last "clamp" N
Type I used, ended up with a dose of epoxy in the braid seal (the weak spot for
strength) making them a one use only connector. Not quite as good as oil filter
wrenches but I've never seen one of those wrenches that small.
