What the 176152-3 Jackscrew Socket Does in the Assembly
The TE Connectivity 176152-3 is a jackscrew socket kit from the AMPLIMITE series, designed as a screwlock accessory for D-subminiature connectors. It provides the mechanical retention that keeps a mated D-sub pair from vibrating loose — the jackscrew pulls the plug and receptacle together and holds the interface under tension. The kit includes the socket and the mating screw, with a thread configuration of M2.6 socket and 4-40 screw, and a length below head of 0.312" (7.92 mm) that suits standard D-sub panel thicknesses. Hardware is included in the bagged package, so it arrives as a ready-to-install set.
The thread size is the critical fit parameter: M2.6 socket on the receptacle side, 4-40 screw on the plug side. This dual-thread arrangement is standard for AMPLIMITE D-sub connectors — the M2.6 end threads into the receptacle's threaded insert, and the 4-40 screw passes through the plug's mounting hole and engages the socket. The 7.92 mm length below head provides clearance for panel thicknesses up to about 3 mm before the screw bottoms out. If you are replacing a missing or stripped jackscrew on an existing AMPLIMITE D-sub, this kit matches the factory hardware.
Compatibility with AMPLIMITE Connectors
The 176152-3 is listed for use with AMPLIMITE series connectors. This covers the standard-density and high-density D-sub shells in the AMPLIMITE family — the jackscrew mounting hole pattern and thread pitch are consistent across the series. It will not fit non-AMPLIMITE D-subs that use a different thread (e.g., M3 or 4-40 UNC on both ends) or a different socket depth. For a standard AMPLIMITE D-sub plug and receptacle pair, this kit is the correct retention hardware.
