Torque Wrench Drive

[Camerashy]

Just done a search as best as possible as I'm a bit confused on the size I would need to fit my 2014 A4 wheel nuts.
i know the torque should be 90 pounds or 120NM but do I need the 1/2in or 3/8in fitting for the wrench and please.....does it come with this fitting or do you buy them separately
Also noticed that some only go up to 90NM so can I assume that the ones greater than 120NM are top of the range and the more expensive
thanks

You should buy a 1/2 inch square drive wrench and a 17mm socket [*] and a 5 inch extension bar.
[*] check this, I don't know if newer >2005 cars are different.

Most 1/2" torque wrenches go up to 200 nm. Make sure it has a certificate of calibration (cheap ones are wildly inaccurate)

A deep 17mm socket will do the job usually. And get a "breaker bar" for undoing the nuts.
