The TE Connectivity 5205817-1 is a jackscrew socket from the AMPLIMITE HD series, supplied as a hardware accessory for D-subminiature connectors. It comes as two complete sets per bag, each set including a 4-40 socket and a 4-40 screw — the threaded portion below the head measures 0.312" (7.92 mm). This is not a connector; it is the retention hardware that secures the mating halves of an AMPLIMITE HDF or HDP series D-sub connector pair, preventing the interface from vibrating loose in industrial or field-service environments.
Thread Size and Compatibility
The 4-40 thread is the standard UNC size used across the AMPLIMITE HD family and most industry D-subs. The 0.312" threaded portion gives enough engagement to pass through a standard D-sub panel-mount flange and still leave thread for the mating screwlock post on the plug side. The 5205817-1 is explicitly listed for use with AMPLIMITE Series HDF and HDP connectors — these are the high-density D-sub variants with 0.090" contact spacing. If you are building a cable assembly with an HDF or HDP plug and a matching receptacle, this jackscrew set is the correct retention hardware.
What You Get in the Bag
Two complete sets per bag — each set comprises one 4-40 female jackscrew socket and one 4-40 male screw. The hardware is included in the package, so no separate sourcing of screws or washers is needed for a two-connector assembly. The Bulk packaging means the sets ship loose in a bag, not on tape or in a tube, which is standard for hardware accessories.
