It carries a dual thread configuration — a 2-56 socket on the female end and a 4-40 screw on the male end — giving it the reach to lock a plug and receptacle together through a panel. The length below head measures 0.405\" (10.29 mm), which sets the panel thickness it can bridge and the thread engagement depth available. This is a standalone accessory; it is not included with a standard D-Sub connector and must be ordered separately when the application calls for screw-lock retention rather than slide-locks or a center-jackscrew. ## Thread Compatibility and Panel Fit The dual-thread arrangement is the key selection parameter. The 2-56 socket threads onto the mating D-Sub's male jackscrew post (common on AMPLIMITE.050 receptacles), while the 4-40 screw passes through the panel and threads into the connector's female standoff on the other side. The 0.405\" below-head length means this socket works with panels up to about 0.090\" thick before the screw bottoms out — thicker panels reduce the available thread engagement, so confirm the stack-up against the 4-40 thread depth in the mating hardware. The socket is intended for use with AMPLIMITE series connectors; it is not a universal D-Sub jackscrew and may not thread onto hardware from other families with different post diameters or thread pitches.","metaTitle":"TE 749087-1 AMPLIMITE .050 D-Sub Jackscrew Socket, 2-56/4-40","metaDescription":"TE Connectivity 749087-1 AMPLIMITE .050 D-Sub jackscrew socket.
