Default BNC connectors 75 Ohm versus 50 Ohm?

I recently was able to use a crimp on tool for F connectors for RG-6 quad
shield coax. To make sure everyone understands, I am in Israel, and RG-6
quad shield coax is cheap and easy to find.

Any other coax is almost impossible to find. Pl-259 connectors, called
"UHF" connectors here are rare items. I can get them locally, but I have
to special order them and they are expensive. Since I can not see them
before I order them, I am as likely to get nickle plated ones with
phenolic insulation as I am to get any other kind, and once ordered are
not returnable.

BNC to PL-259 adaptors, are easy to get, and can be ordered from a reliable
local souce for a relatively small price. The same with N to PL-259.

Looking around at the crimp-on F connectors before I ordered them, I found
that you can get crimp on BNC connectors for RG-6 quad shield coax.

Here's my questions, Note when I say crimp-on, I mean the ones that crimp
from the rear, like commerical F connectors, not the ones that crimp
around the plug. I have never been able to get any of them to "fit right":

1. Can I connect a 75ohm BNC plug (which is a different size) to a
50oHm BNC socket?

2. Are there crimp on 50 ohm BNC plugs which will work with RG6 quad shield?
I know there are variations, but most are similar in size.

3. Are there crimp on N connectors that would fit the RG6 quad shield coax?
More likely due to the size a crimp on center element that screws into the
plug body?

4. Are there crimp on PL-259 connectors?

Thanks in advance,

Geoff.
