The TE Connectivity 201389-1 is a jackscrew socket from the M Series, designed as a panel-mount accessory for M Series circular connectors. It carries a 6-32 double thread — the thread size and type that governs compatibility with the mating jackscrew or receptacle hardware. The part ships in Bulk packaging, suitable for production runs where individual bagging is unnecessary.
Thread Spec and Connector Fit
The 6-32 double thread is the defining spec for this jackscrew socket. It means the thread form is UNC 6-32, and the double-thread feature allows faster engagement — each full turn advances the screw twice the pitch of a single thread. This socket mates with the corresponding jackscrew (male) half on the mating connector or panel. It is intended for use with TE's M Series connectors, which include the common MS-style circular types used in military, aerospace, and industrial control applications. The female thread accepts a standard 6-32 screw, so field replacement with a common hardware-store screw is possible in a pinch, though the double-thread design is specific to the intended jackscrew.
