We probably have muttered “Righty tighty, lefty loosey” when trying to put a nut on a bolt, but when you are starting a nut on a bolt, turning it lefty loosey first, then righty tighty helps align the threads of the nut and bolt. This reduces your chances of cross threading the nut and bolt!
This lefty loosey function is even built into most automatic/robotic screwdrivers in modern factories
What’s a cross-thread? let’s hope you never have to find out!
