The HARTING 09670009924 is a jackscrew socket for D-sub connectors, not a connector itself — it's the threaded fastener that pulls a plug and receptacle together and holds them mated under vibration. The dual-thread design gives you a 4-40 socket on one end and an M3 screw on the other, so it bridges the UNC and metric worlds in a single part. Hardware is included, meaning the screw and any retaining hardware ship with the socket. It's a standard accessory for any D-sub shell that accepts a 4-40 or M3 jackscrew, which covers the vast majority of standard-density and high-density D-subs on the market.
The 4-40 Socket thread mates with the standard 4-40 UNC jackscrew found on most D-sub backshells and hoods. The M3 Screw thread gives you a metric option for panels or brackets that use M3 hardware. The length below head is 0.315" (8.00mm), which sets the standoff between the D-sub shell face and the mounting surface — enough to clear most PCB-mounted D-subs and backshells. If you need a longer reach, the sibling 09670019973 gives you 0.398" (10.10mm); for a shorter footprint, 09660009972 comes in at 0.146" (3.70mm) with a 4-40 socket and 4-40 screw.
