It carries a thread size of 2-56 on the socket end and 4-40 on the screw end, with a length below head of 0.223\" (5.66 mm). ## Thread Size and Compatibility The 2-56 socket thread accepts the standard jackscrew found on most AMPLIMITE.050 D-sub connectors, while the 4-40 screw thread matches the common panel-mount or backshell hardware. This dual-thread design means the 749087-3 can be used as a replacement or build-up part for any AMPLIMITE.050 D-sub assembly that uses a 2-56 socket / 4-40 screw locking system. It is compatible with standard D-sub connectors that follow the same thread convention, but the 0.050-inch contact pitch of the AMPLIMITE series is the specific housing family it was intended for.","metaTitle":"TE 749087-3 AMPLIMITE .050 D-Sub Jackscrew Socket, 2-56/4-40","metaDescription":"TE 749087-3 AMPLIMITE .050 jackscrew socket for D-sub connectors.
