D38999/44 is the jam-nut-mount receptacle of MIL-DTL-38999 Series IV. Instead of a flange with mounting holes, the shell passes through a single circular cut-out in the panel and is secured from behind by a jam nut and lockwasher — a layout that saves panel area on a crowded bulkhead and lets the connector be positioned freely rather than on a bolt pattern. That makes it the standard choice for instrument panels, junction boxes and equipment racks where several connectors are packed into a small face. Series IV's 90-degree breech-lok coupling gives the same audible, tactile and visual mating confirmation as the rest of the family, with the 1000 lb-in bend-moment rating and 500-cycle durability that suit cables carrying real mechanical load.
