Pin Gauge
Product Description
Shaped as a cylinder, the scale is read from the diameter of the cylinder, when measuring, the plug gauge perpendicular to the cross-section of the round hole, through the round hole. If you can not pass, then replace the smaller diameter plug gauge; if you can pass and the gap is too large, then replace the larger diameter plug gauge. Until the search for the appropriate plug gauge to pass through the round hole, and there is a slight sense of friction (need to feel the judgement), then the inner diameter of the round hole that is the diameter of the pin-type plug gauge.
