Gage blocks "wring" together for two reasons. First, there is an adhesive action because of an ultra-thin film of oil or moisture between the blocks. Second, there is a molecular attraction, or bonding, between the blocks because of the very flat and parallel mating surfaces.
Keep in mind that a Go plug has a plus tolerance and is designed to gauge the smallest acceptable hole size, and a NoGo plug has a negative tolerance, designed to gauge the largest acceptable hole size. Subsequently a Go gage should be able to pass through the hole and a NoGo plug gauge should not. This is why they call it Go NoGo gauging. Others call it Fixed Limit Gauging.
