Hi there I have been tossing this question around to diffrent people and it seems everyone has a diffrent answer. Here goes if you have a hole say its 1.000 +.0001 -.0002 what size pins would you used for your go and no go. I would chose a .9996 and a .9999 pin. To me you need .0002 clearance for a pin to fit into the correctly sized hole. I don't see how a size for size pin would fit even though that is what some of the inspectors say. I also asked our GD&T guru if there was a standard for what size pin will fit in what size hole he did not know of any inspection standard when it comes to this situation. Thanks for your feedback.
Merry Christmas & Happy New Year to All
