Find out the minimum and maximum torque forces for the SMA, TNC, BNC and N interfaces.
Torque Forces Table
The recommended torque force is for guidance only. The actual torque force needs to be checked and finalised by the customer based on their actual working application.

Notes
Customer should verify the torque based on different bulkhead materials.
If used in a environment exposed to vibration we recommend using thread-lock or an additional locknut.
The difference between standard and reverse polarity RF connectors is small and subtle, but of utmost importance when it comes to your design. Watch the video below to learn how to tell them apart.
