Question

why does a bolt always opened in anticlockwise direction

Answer 1

hey friend :-)

here is your answer

Because when machineries rotating at high speed in clockwise direction,there will be high centrifugal force, because of which the clockwise nuts will open due to clockwise inertia and centrifugal force on the nut.

When we use an anticlockwise nut,the clockwise forces will help it in keeping tight and not opening.

hoping it helps

thanks :D
