Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The Internet was still largely an unknown entity at the time and not much was available in the form of WYSIWYG ...

RF Coaxial Connector Torque Specifications

Properly torqueing of threaded RF coaxial connectors is essential for reliable, maximum performance interfaces. It not only ensures that the initial contact is proper, it also protects against changes in geometry during handling and operational environment conditions.

Connector Coupling

These values were originally pulled from Agilent's calibrated torque wrench page, but it has disappeared. Additional information gathered from other online sources such as the Huber+Suhner and Radiall websites. Torque values can vary considerably between vendors.  1 lb-in = 11.30 N-cm

Fairview Microwave sells calibrated torque wrenches.
