I own a few boxes of pin gages. All of mine are marked 'minus'. I see you can also buy 'plus'. Why would you want one or the other? metalmagpie
Because as manufacturers, we know there is no such thing as Zero.
Plus/Minus is just a preference. If you use a Plus pin you know which side of the Target you are on. Same thing with Minus. I prefer Minus, because I think it answers my question better, about how close to the Target I am.
