Right-hand vs Left-hand Threading

Almost every threaded component on a bike is going to be right-hand threaded, which means that turning it clockwise will tighten it and turning it counter-clockwise will loosen it. Pedals and bottom bracket cups are examples where you would run into left-hand threaded components. To identify the handedness of a component hold it in front of you as in the picture below. The direction that the threads slant up too corresponds to the components handedness.
