Several have suggested that these are 10-32 connectors.  If this is
true, a 10-32 nut will thread on them with no trouble.  I believe these
**may** be the 1/4" diameter variant that was 93 ohm characteristic
impedance.  I **think* they are called an S-93.  Still 32 tpi, but 1/4"
in diameter. You can test the thread pitch with a 6,8, or 10-32 bolt.
There was another even more obscure connector that used a coarser pitch. 

And before the 'not 50 ohm' firestorm starts - it doesn't matter.  This
is only 6" or so of cable, the mismatch impact is miniscule at this
frequency.  They were far more concerned with mechanical ruggedness.
