It combines a 2-56 socket thread on the panel side with a 4-40 screw thread on the connector side, allowing the jackscrew to secure a D-sub to a panel or mating half. The slotted drive head accepts a flat-blade screwdriver for field installation or removal. Length below head is 0.255\" (6.48 mm), which sets the panel thickness the jackscrew can accommodate when fully threaded. The 750644-1 mates with standard AMPLIMITE D-sub connectors that accept a 4-40 screw on the connector face. The 2-56 socket end threads onto a mating panel stud or another jackscrew. The slotted drive allows torque application without a specialized tool — a standard #1 or #2 flat-blade screwdriver works. The 0.255\" below-head length means the threaded portion extends through panels up to roughly 6.5 mm thick before the head seats.","metaTitle":"TE Connectivity 750644-1 Jackscrew Socket, AMPLIMITE","metaDescription":"TE Connectivity 750644-1 AMPLIMITE jackscrew socket, slotted, 0.255\" below head.
