Torque Specs

In your example, for the bracket to upright (did I get your question right?) use any engineering book or fastener supplier's handbook to find the torque specs. Make sure you use the correct (or no) lubricant.

To learn more about this "mess" get ARP's catalog & tech articles. And Carroll Smith's book about nut, bolts and fasteners.

Good advice from Dominik, and sensible advice on Carroll Smith's books. A good one to start with is Carroll Smith's "Engineer to Win ...Understanding Race Car Dynamics".
No surprise that there's a chapter there on threaded fasteners. He can be quite entertaining as well as very informative.
And no, I'm not related

Cheers!
