works well and a good fit

Good
The wrench came with 0.9Nm torque set in factory, which is the recommendation for 2.92 and 3.5mm connectors. However for SMA connectors 0.57Nm is the right torque, so I adjusted the wrench to meet SMA standards. The tuning range of the torque is quite huge, so I only tested It between 0.4 to 1.2Nm, fair enough! Good price as well. Hope It will last in time, and I will check the torque from time time to ensure the spring is not getting tired with time ! Well done !

Useful tool, but handle with care.
Useful tool for SMA connectors. Not sure about the accuracy but seems to be okay. Points to note are when connecting to a SMA socket on a PCB always use another spanner to support the PCB SMA otherwise this can be broken away with the torque produced. Also of note is that in proper use the correct torque is applied when just at the break point and the break point should not be taken to the total 90degrees as some/most demonstrations show.

value for the money
I recently got my hands on the Torque Wrench designed for SMA 8mm RF Connectors, and I'm thrilled with its performance. This tool makes tightening these connectors an absolute breeze. With a torque setting of 1Nm, it's precise and ensures a snug fit without the risk of overtightening. The build quality feels solid, and it's easy to use even for someone like me who isn't an expert in connectors. I highly recommend it to anyone in need of a reliable torque wrench.

Alloy RF Coax Torque wrench
This RF wrench has been Machined to a good standard and feels a good quality in the hand its a 8mm head with a torque system as you tighten the threads the head folds 90 degrees it does this when the correct tightness is achieved its alloy steel and it seems high quality componants we're used through out production It has a blue plastic protective case to keep it like new there is some literature included but it's written Chinese It's a useful tool to have if you do a lot of analogue airiel projects and thing like that

Torque appears to be too high, and it is expensive.
ThreeH Torque Wrench for SMA 8mm RF Connector 1Nm High Accuarcy Electrommunication Coax ……. This is a very simple tool for torquing up SMA connectors. It uses a spanner type end which is held in position by a spring tensioned ball, this allows the spanner to rotate 90 degrees once the correct torque is reached. I have tried it on a few SMA connectors and so far, I am unconvinced that it is the correct torque as on two occasions it has stripped the threads on the SMA connector and on another it rotated the SMA socket and tore off the soldered connections requiring the equipment to be opened and repaired. This tool is useful as a handy spanner to tighten SMA’s but I think the torque is maybe too high and there is no way to alter it. Also, the current price for a dedicated tool (even if it worked well) is far too high. I have paid less for a heavy-duty torque wrench! I’m not impressed with this SMA torque wrench at all. I will be using it as a standard spanner.
