One interesting point is that the Amphenol web site shows the standard type 
bulkhead mount connector - the UG-1094/U type - but has no spec on the thread 
or the thread tolerance. There probably is a MIL spec on the thread tolerance, 
but I suspect that you would have to buy proper MIL spec connectors to get it. 
The standard BNC thread is 3/8-32 UNEF: from memory, it's a 2A tolerance. I 
find that 3/8-32 ME (Model Engineer) thread tap and die are close enough for 
all practical purposes, even though they are a 55 degree Whitworth form rather 
than the 60 degree Unified form thread.
It's maybe worth checking the diameters of the connector and the nut.
