The TE Connectivity AMPLIMITE 5206514-1 is a sliding lock post kit — a D-sub accessory, not a connector itself. It provides the threaded jack-screw mechanism that secures the male D-sub shell to the mating receptacle, preventing the cable or panel vibration from working the connection loose. The 4-40 thread is the standard D-sub hardware size, and the 0.300" (7.62mm) length below the head is sized for standard-density D-sub backshells and hoods. This kit is specifically listed for use with AMPLIMITE Series HDE, HDF, and HDP connectors — the standard commercial and industrial D-sub ranges from TE. If you are building or repairing a harness with those connectors, this lock post replaces a missing or worn jack-screw without swapping the whole connector.
Thread Size and Fit Check
The 4-40 thread matches the standard UNC 4-40 jack-screw found on nearly all DB-9, DB-15, DB-25, and larger D-sub connectors. The 0.300" (7.62mm) length below the head is the standard reach for panel-mount or cable-hood applications — long enough to engage the mating threaded insert, short enough not to bottom out in a standard backshell.
