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.
