Hi, I am the OP.  I can see that the threads of the plug and socket 
would grip one another and probably make good electrical contact.

However, I can't see the wire centre connector necessarily making 
electrical contact through that grease.  

Does the centre conductor actually have to make electrical contact or 
is 240 MHz RF able to propagate properly across the plug/socket join 
even if the centre conductor is not electricially continuous?
