righty-tighty, lefty-loosy
Right-hand screw refers to a screw where the thread angles clockwise about the axis of the screw. This means that you must turn clockwise to tighten the screw or screw on a lid, and counter-clockwise to loosen the screw or unscrew the lid 12. In English, there is an easy rule to remember: “righty-tighty, lefty-loosy.”
Right hand thread is the most common as it follows the direction we are used to. It is also ergonomic, as most people are right-handed and can therefore better use their right hand to tighten the screw. Psychologically speaking, we are also used to this kind of tightening and loosening direction.
