The Harting 09660009972 is a jackscrew socket for D-Sub connectors, designed to secure the cable-side plug to the panel-mount receptacle. It carries a 4-40 Socket and 4-40 Screw thread — the standard UNC thread for standard-density D-sub shells, so it mates with the matching screw on the mating half. The socket has a 0.146" (3.70mm) length below the head and a 0.106" (2.70mm) threaded portion below the head, sized for the typical D-sub shell thickness and panel clearance. It ships in a Bag and is ROHS3 Compliant, ready for EU and global BOMs.
Thread Size and Compatibility Check
This jackscrew socket is the female half; it mates with a 4-40 male screw on the opposing connector half. If you are replacing a missing or damaged jackscrew on a D-sub plug, this is the correct part for the socket side. The 0.106" threaded portion below the head is enough to engage the mating screw through a standard shell thickness of about 0.060" to 0.090".
