They look identical to the ones I have. The pin is simply screwed into a rubber disc and can easily be removed. Just unscrew the pin using a suitable wet of pliers.

I keep a few with pins if I do want to short the input.

Sounds like a lot of work. I leave the probe plugged in :)

It is.  :phew:

Knowing that my BNC connections are protected and dust-free allows me to sleep at night.
Bob Sava:
Only 500 mating cycles?  This makes me wonder if 3 year scope warranty covers BNC connectors.
metrologist:
What constitutes a failure? These connectors are rated to some performance up to 1GHz (0.2dB IL).

If you are paranoid about life then put a short extension on it.

For BNC something like this (check it first): https://www.aliexpress.com/item/Pro-Electrical-Accessories-BNC-Male-to-BNC-Female-Jack-in-Series-Right-Angle-RF-Adapter-Connector/32815909617.html

Or a straight through version.

500 rated mating cycles does not mean it will fail after being used 500 times. It simply means they don't guarantee it to meet spec anymore.
I've used a 200 cycle rated connector over 10,000 times and its still functional for what I use it for. Of course it may be well out of spec in terms of contact resistance at this point.
