When building a coax cable can I use a male D-sub pin instead of the pin supplied in the connector bag?

Tried to crimp those pins with a D-sub crimper and it didn’t go well. I now have extra connectors with no pins.

You could use a piece of clipped off a paperclip if you could get it to stick. The problem is reliability.
Those pins are designed to "click" inside the connector, or be seal with a silicone o-ring. Until moisture seeps in, just leaving the center wire sticking out will work just as well as the crimped pin. Getting the connector to go together without bending the center wire and destroying the connection . . let's say I've done it, but don't really want to do it again.
I'm pretty sure you can get just the pins fairly cheap.

I had a similar situation.† I substituted a D-sub pin and it seems to have worked well.
With that said, I'm ordering some extra pins for my remaining orphan plugs per Bob's post.

There is, of course, a specialty crimper. The ratchet crimper I have has small holes for crimping the pin and then a larger hole to crimp the ferrule. Something like https://tinyurl.com/y7tv4jzl

The tool you crimped the hex-sleeve should
have a die for pins

NOT A GOOD IDEA. The pin retaining mechanism
for these two technologies could not be more
different. Further, the d-sub pin o.d. is
0.040" while the BNC pin o.d. is 0.052"

NOT a good match.
