Subject: Does fatigue apply to preloaded fasteners too ?

Basically my understanding from my machine design course (Juvinall) is 
that fatigue (endurance limit of the bolt) is used when sizing a bolt.  
Such concept has always been my understanding (either in tension, shear or 
both).  

  I found a web page (www.avweb.com/articles/bogustor.html) that states 
that bolts are not affected by fatigue ?.  My understanding so far has 
been that all machine components & joints are affected by fatigue.  This 
includes bearings, gears, welds joints, bolts, etc.

Thanks,
