Does any one have any recommendations on what torque settings I should be going for when tightening my rear axle bolt (non quick release)?

I was thinking around 14 Nm?

My guess would be 15-20Nm.

DT Swiss have a doc for their RWS, recommending 15Nm, which I take as a ballpark figure because they do not differentiate between different axle sizes. Whereas in strict engineering terms, the max recommended torque is dependent on the bolt and thread size.

You can google for bolt torque charts, but I think they specify max torque values that are much higher than what you need on a bike.

I use a torque wrench on the bike where possible, but wheel axles is one place I don't. Most through axles come with a hand lever, so you cannot easily attach a torque wrench to them. So I just do them up "tight" with 2 fingers on the lever. I would do the same on an axle with nuts, using a spanner, and not overthink it. Just remember the spanner being longer than the RWS handles gives you much more leverage so don't go too hard.

I have a few RWS levers in my garage, and am not sure how you'd go about measuring torque on one (unless it was one of the newer ones with a removable handle).

I also have a couple tooled thru axles, and those have torque specs printed on them. I don't bother putting a torque wrench on them, though. I just tighten them to "snug" which is a far cry from how I tighten cassette lockrings, for example. If they loosen, I know I didn't tighten them enough the first time, which hasn't happened.
