D38999/24WJ20SN is a MIL-DTL-38999 Series III jam nut mount receptacle in shell size 25 with the J-20 insert arrangement and socket (female) contacts in an olive drab cadmium (class W) finish. The jam nut style secures through a single panel hole with a hex nut rather than the four-hole flange of the /20 wall mount body, so it suits bulkheads and castings where only one mounting hole is available. Series III’s triple-start thread with self-locking ratchet is scoop-proof and resists vibration loosening.
