Jackscrew Socket for AMPLIMITE HDE-20 D-Sub Connectors
The TE Connectivity 5745563-1 is a jackscrew socket — a threaded fastener designed for AMPLIMITE Series HDE-20 D-subminiature connectors. It provides the locking mechanism that secures the connector pair against vibration and accidental disconnection in panel-mount or cable-mount applications. The 4-40 socket and 4-40 screw thread combination is the standard size for standard-density D-sub shells, so this part directly replaces the factory-installed jackscrew on an HDE-20 receptacle or plug.
Thread Size and Fit
Thread size is 4-40 socket and 4-40 screw — the UNC 4-40 pattern is the industry norm for D-sub jackscrews. The threaded portion below the head measures 0.250" (6.35 mm), which matches the standard clearance hole depth in most D-sub backshells and panel-mount flanges. If you are replacing a missing or stripped jackscrew on an AMPLIMITE HDE-20 connector, this is the direct drop-in part.
What's Included
Hardware is included — the jackscrew socket ships with the mating 4-40 screw, so you get both halves of the locking pair in one order. No need to source a separate screw or nut. The part comes in Bulk packaging, which suits repair kitting or small-run harness assembly where tape-and-reel is unnecessary.
RoHS compliant per current directive.
