The one I use is this;

The only problem is that you get more bits than you need, I later came across the same driver/setter but with less bits and not as expensive because of having less bits.

I also got this;

And this;

I needed these because the Wiha is a VDE instrument and the drive is not quite 1/4" for safety reasons.

Over the top? maybe so, but I like prescision and repeatability.

I settled on 1.6nm for the clamp bolts, and 1.0nm for the scope caps. This was equating to a tad under what I used with normal hex keys using the "tight with the short end plus 1/4 turn with the long end" method.
