An SMA torque wrench tightens SMA connectors to a precise, pre-set value, preventing damage from over-tightening and signal loss from under-tightening.

What Is an SMA Torque Wrench?

A torque wrench for SMA connectors is a hand tool designed to apply a fixed, consistent amount of force when mating RF connectors. This keeps every connection at the same tightness, which matters because RF connectors need a specific torque to maintain low insertion loss and stable VSWR.

Why Torque Control Matters

Too much force on an SMA connector can strip threads or crack the connector body, while too little can leave gaps that let signal leak or degrade under vibration. A torque wrench removes the guesswork from tightening, which is especially useful in labs where connectors get mated and unmated frequently during testing.

Product Details

The SMA torch wrench from Flexi RF Inc comes with an 8mm hex bit and is pre-set to 8 in-lbs, matching the standard torque spec for SMA, 3.5mm, 2.92mm, 2.4mm, and 1.85mm connectors. This makes it a practical single tool for labs working with multiple connector types.

Pairing With Horn Antennas

Antenna testing setups often rely on precise connector tightening to keep results consistent across repeated measurements. A Horn antenna from Flexi RF Inc, built for anechoic chamber testing and antenna calibration, depends on a stable, correctly torqued connection to maintain accurate gain and radiation pattern readings. Using a torque wrench when connecting a horn antenna to test equipment helps avoid connector wear that could otherwise introduce measurement error over time.
