JACKSCREWS & JACKSOCKETS
Jackscrew Locking Devices
Polarized jackscrews offer the ease and
assurance of threaded positive coupling.
They are particularly desirable for the larger
connectors (XMRE 34 and larger) whenever
they are to be used in locations that make it
difficult to apply enough direct pull to
separate the two halves of the connector.
Type C (long-turning jackscrews and
jacksockets) or Type D (monojacks) must be
specified if both jackscrews and hood are
required on the same connector half.
Monojacks eliminate the need for roll pins,
spacers and washers.

Note 1: Weights are given for pairs, i.e., for a jackscrew and a
jacksocket, etc., so that the weight figure may be added once to the
weights of other accessories when computing the total weight of a plug
or receptacle.
Note 2: Weights of turnable jackscrews and turnable jacksockets include
knobs and roll pins; weights of fixed hardware include nuts.
DIMENSIONS
Drawings show extension of knobs beyond shell (left) and beyond hood. Refer to details
of shells and hoods for the other dimensions which vary according to connector size.
