  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.

  Bulkhead Thread Mounting Torque	Connector	Material	Torque Min in-lbs	Torque Max in-lbs
  1/4 - 36 UNS - 2A	SMA	Brass	7	10
  1/4 - 36 UNS - 2A	SMA	Stainless Steel	12	15
  3/8 - 32 UNEF - 2A	Isolated SMA	Brass	16	20
  1/2 - 28 UNEF - 2A	TNC	Brass	20	25
  1/2 - 28 UNEF - 2A	TNC	Stainless Steel	25	30
  1/2 - 28 UNEF - 2A	Isolated TNC	Brass	20	25
  3/8 - 32 UNEF - 2A	BNC Front Mount	Brass	16	20
  1/2 - 28 UNEF - 2A	BNC Rear Mount	Brass	20	25
  5/8 - 24 UNEF - 2A	N	Brass	30	35

  Notes
  

  1. Customer should verify the torque based on different bulkhead materials.
  2. If used in a environment exposed to vibration we recommend using thread-lock or an additional locknut.

• Rear & Front Mount Differences

  View our video guides to see the key differences and advantages between the two mount styles.
• Standard & Reverse Polarity Differences

  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.
• MHF - U.FL Intermateability

  Are Hirose U.FL and I-PEX® MHF® connectors compatible and intermateable? The answer is Yes. If you want to learn about all the details, read to our article here: MHF® - U.FL
