Often in install or specification manuals you will see something like:
Tighten X turns past finger tight
This has always bothered me as it seems ambiguous. I've always taken this to mean a "turn of the hand". Depending on flexibility, seems like this would be a little less than 180 degrees?
However, it could also easily be interpreted as a full rotation (360 degrees)....
I'm honestly surprised that the lawyers allow this in technical specs like the example above (why not just give torque?).
