AMPLIMITE Jackscrew Socket Kit — 4-40 Thread, Hardware Included
The TE Connectivity 5748271-1 is a jackscrew socket kit from the AMPLIMITE series, designed as a screw-lock accessory for D-subminiature connectors. It includes both the 4-40 socket and the 4-40 screw, so the kit arrives complete — no need to source the mating screw separately. The 4-40 thread size is the standard UNC thread for standard-density D-sub hardware, meaning it fits the threaded inserts found on most AMPLIMITE D-sub hoods, backshells, and panel-mount receptacles. The 0.312" (7.92 mm) length below head suits the clearance depth inside a typical D-sub backshell or hood.
