These torque values are applicable for threads only and do not apply to hardware assemblies. These torque
values are approximate and should not be accepted as accurate limits. Indeterminant factors in specific appli-
cations preclude the publication of accurate torque values for universal use.
Unless specified otherwise, dimensional tolerances are:
1) ±0.001 inches (0.03 mm) for male contact mating diameters.
2) ±0.003 inches (0.08 mm) for contact termination diameters.
3) ±0.005 inches (0.13 mm) for all other diameters.
4) ±0.015 inches (0.38 mm) for all other dimensions.
5) ±0.0015 inches (0.038 mm) for all press-fit contact terminations.

Male and female signal contacts, size 22. Terminations may be crimp, solder cup and
printed board mount.
Male and female signal contacts, size 20. Terminations may be crimp, solder cup, wrap
post, press-fit and printed board mount.
Unloaded connector insulators, male and female. Insulator retention system retains all
contact termination types. Insulator may be used as a free or fixed connector.
Loaded connector insulators, male and female. Insulators may be preloaded per cus-
tomer requirements with contacts having terminations of 90° or straight solder printed
board mount, wrap post, solder cup and press-fit. Insulator contact positions may be
selectively loaded with contacts. Connectors are normally fixed panel or printed board
connectors.
Fixed female jackscrews are the stationary threaded members of the non-polarized
jackscrew system.
Fixed male and female jackscrews are the stationary threaded members of the polarized
jackscrew system.
Rotating male jackscrews and screwlocks are the rotating threaded members of the non-
polarized jackscrew system.
Rotating male and female jackscrews are the rotating threaded members of the polarized
jackscrew system.
Vibration locking system consists of lock tabs on fixed connector and slide lock lever on
free cable connector.
Blind mating connector system with pilot probes on free connector and receptacle guides
on panel mounted fixed connector.
Cable adapters (Hoods) are used on the free cable connector to provide cable support
and contact protection.
Knobs of the polarized rotating jackscrew system are affixed to the rotating jackscrew by
a set screw.
