The TE Connectivity 552113-1 is a jackscrew socket from the CHAMP.085 series, designed as a mounting accessory for CHAMP D-Sub connectors. It carries a 4-40 thread — the standard size for D-Sub jackscrews — and a hex head for tool-driven installation. The length below head is 0.750" (19.05 mm), which sets the maximum panel or bracket thickness the screw can pass through before engaging the mating thread. This is a hardware component, not a signal-carrying connector: its job is to secure the connector pair and provide the mechanical clamping force that keeps the D-Sub interface mated under vibration or cable strain.
Thread Size and Panel Fit
The threaded portion below the head measures 0.375" (9.53 mm), so the effective thread engagement depth is about 0.375" into the mating jackscrew or standoff. The 0.750" overall length below head accommodates a panel thickness up to roughly 0.375" before the screw bottoms out — enough for most metal or plastic enclosures. If your panel stack-up is thicker, you will need a longer jackscrew such as the 5229996-2 (0.425" below head) or the 5229911-2 (0.370" below head).
The official base product number is 552113, which covers the family of CHAMP.085 jackscrews; the -1 suffix denotes this specific hex-head, 4-40 socket variant in Bulk packaging.
