Jam nut tightening torque

For jam nut receptacles of series :

  • MIL-DTL-38999 series I and III (TV-CTV and LJT)

  • Powersafe

  • RNJ(LP)

  • SC39

  • RJFTV

  • USBFTV

  • TVµCOM

Jam nut tightening torque value will be as follows:

Shell sizes : RJFTV = 19 / USBFTV = 15 / TVµCOM = 11

    • For 387TV series jam nut receptacles, apply torque values of shell size 9.
    • For reduced flange versions (F311, F312, F058, F059) and other versions with castle nut, torque value is the same as standard ones.
    • Apply the torque with recommended tool from the catalog.

For jam nut receptacles from series :

  • MIL-DTL-38999 series II

  • PT/451

  • RJF

Tightening torque will be as follows:

Shell sizes PT/451 : RJF = 18

 

For 2M Micro Miniature series :

Important note :

We recommend a first tightening with above torque values, and then a second tightening after 24 hours for better vibration resistance.

In the case of your jam nut receptacles are subjected to high levels of vibration, certain solutions are available such as :

  • Use of safety wire :

  • Use of thread lock -> Risk that the connector won't be removable anymore

 

  • For square flange receptacles, you should apply standard M3 tightening torque on the screws.
