Current Topic:
Why loosening torque is lesser than the tightening torque for bolts/screws
Over time, practically all materials relax a little.  When you tighten the screw or bolt, you'll use enough torque to get the pretension you want.  Then the pretension reduces over time which means less torque is required to remove it.  In this case time is relative and the amount needed will vary by material.
