So, I'm buying some C7 ballscrews and I've never preloaded anything before.

I'm planning on using a torque wrench or a torque meter of some description. Now what I don't understand is how one deduces the newton meter or foot pounds of force to tighten the the nut appropriately, It requires about 2% of the CA figure which is 13800 newtons or 276 newtons. How do I take this newton figure and calculate the newton meter figure?

Any help would be greatly appreciated!

Thanks.
