which way is always a matter of perspective , example if the bolt head faces away from you then you perceive it is turning backwards
but the threads in the bolt are still the same.

reaching across a wheel hub and trying to re true a wheel after breaking a spoke (brake pads as reference,
to get the wheel to roll again, that is a consideration to bear in mind.

{Turnbuckles, as an example, are 3 pieces, and loops on either end, are RH thread on one end, LH thread on the other }
