The HARTING 09670019973 is a jackscrew socket, not a connector — it is the threaded female half that captures the male screw on a D-Sub backshell or hood, pulling the connector pair together and holding them mated under vibration. The 4-40 UNC thread is the standard size for standard-density D-Sub hardware, so this socket mates with any 4-40 male screw or standoff used on the matching D-Sub plug or receptacle backshell. Hardware is included in the bag, meaning you get the socket and any necessary retaining clip or washer in one package — no separate hardware order for a single build.
Thread Size and Length — What Fits Your Panel
The 4-40 thread size is the standard UNC machine screw size for D-Sub hardware — the same thread as the jackscrews on a DB-9 or DB-25 backshell. The length below head is 0.398" (10.10 mm), which means the threaded portion that engages the screw extends that far below the flange. If your panel or backshell has a boss or recess deeper than 10.10 mm, the screw may bottom out before the socket fully seats. The threaded portion below head is 0.280" (7.10 mm) — the actual thread engagement length.
Compatibility and Cross-Reference Check
This socket is listed for use with D-Sub backshells — any standard D-Sub hood that accepts a 4-40 jackscrew socket will work. The closest functional peer is the HARTING 09670009924, which also uses a 4-40 socket but has a shorter length below head of 0.315" (8.00 mm). The 09670019973 gives you 2.10 mm more thread engagement, which matters if your panel or backshell has a thicker flange or a deeper counterbore. The 09660009972 is a shorter 0.146" (3.70 mm) version — for thin panels only.
