Left Hand Nut, NC: Most threaded fasteners are right threaded, so you turn them clockwise to tighten them. Some parts which are used in conjunction with rotating shafts would tend to unscrew themselves if they threaded normally, so they are threaded in the opposite direction. This is called a "left thread," "left hand thread" or "reverse thread." *ZB - BLUE ZINC
