Product details

AMPLIMITE Jackscrew Socket — 2-56 Socket, 4-40 Screw

The TE Connectivity 750644-1 is a jackscrew socket accessory from the AMPLIMITE series, designed for use with standard D-subminiature connectors. 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.
