Product details

Jackscrew Socket for D-Sub Connectors

The Molex 1731120380 is a jackscrew socket from the F-GSCH, FCT series, designed as a hardware accessory for standard D-sub connectors. It includes both the 4-40 socket and the mating 4-40 screw, so you don't need to source them separately. The threaded portion below the head measures 0.236" (6.00 mm), which is the standard reach for securing a D-sub plug to a receptacle through a panel or backshell.

Thread and Fit

The 4-40 thread size is the industry standard for D-sub hardware — the same thread used on the mating jackscrew posts of most D-sub connectors. The 0.236" length below the head matches the typical flange thickness of a standard D-sub backshell or panel-mount receptacle. If you're replacing a missing or stripped jackscrew on a D-sub assembly, this part drops in without modification.

Frequently asked questions

Is the 1731120380 compatible with all Molex D-sub connectors?

Yes, it is listed for use with D-sub connectors generally. The 4-40 thread and 0.236" length are standard for the D-sub form factor, so it fits the majority of Molex D-sub plugs and receptacles.

Does the 1731120380 come with both the screw and socket?

Yes, the accessory type is a jackscrew socket, and the features include 'Hardware Included', meaning the 4-40 screw and socket ship together as a set.
