How do I find torque specs?

Begin with the formula T = K x U x D x P, where T is the torque, K is a standard representing 1.33, U is the coefficient of friction, D is the diameter of the fasteners, and P is the necessary preload.

Why do you tighten the nut and not the bolt?

If the friction under the nut face is reduced, then, for a given torque, the bolt preload will be increased. In such situations, it will, in general, be important as to whether the bolt head or nut is tightened. The reason is that each face will have a different friction coefficient.
