The
nut bolt is generally clockwise close around the world. That is if you rotate a
nut bolt clockwise rotation by a screwdriver, spanner- the bolt will close and
to open the bolt you have to rotate it anti clockwise.
But in
power plant this specific rules is not followed because of the heavy vibration
of power plant engines or turbines which is rotating clockwise. If you face
towards the turbine or rotating alternator – its clockwise for you but if you
go behind of the alternator, it will be antic-clockwise to you.
Now
the heavy nut bolt in alternator & turbine assembly in front side is okay
as they are facing rotation vibration in clockwise, but the nut bolt placed
behind the alternator/ turbine will face an anti-clockwise rotation vibration.
This anti-clockwise vibration would cause the nut bolt to loosen up lead in to
disaster. Thus in case of ant-clockwise rotation vibration, the nut bolt is
specially made of anti-clockwise close.
