Outside the model: eccentricity, prying, irregular compression zones, different layer materials, slip, embedment, preload scatter, relaxation, nonlinear contact, full thread model, VDI 2230 and FEA.
Torque T = K * d * Fi is indicative and strongly affected by friction.
The current model assumes nL = 1; the effect of the load-introduction location is outside the scope of this tool version.
