Captive #4-40 Jackscrew for D-Sub Connectors
The TE Connectivity 5229911-2 is a captive jackscrew from the CHAMP.085 series, designed as a slotted accessory for D-Sub connectors. It carries a #4-40 thread and a length below the head of 0.370" (9.40 mm), with a threaded portion below the head measuring 0.250" (6.35 mm). This jackscrew secures the connector to the panel or mating half, providing the mechanical retention that keeps the contact interface stable under vibration and cable strain.
The 5229911-2 mates with standard D-Sub connectors that accept a #4-40 threaded jackscrew — the most common thread for full-size D-Sub shells. The 0.370" below-head length suits panel thicknesses typical of metal-shell D-Sub backshells and hoods; the 0.250" threaded portion engages the mating thread in the receptacle or panel. It is a captive design, meaning the screw stays retained in the connector shell when loosened, so it does not drop out during field service.
