loosen and retighten one at a time.
The idea is to 'break loose' the 'stiction'
of the nut to mating washer surface tension
to get an accurate setting as you re-approach
the proper torque. Then again.....this is more of a
'technique' for proper torque..not necessarily a
'proper procedure' to achieve accurate torque
settings.
