Every pin that i have checked has been 0002 undersize or oversize but that is not a universal given. Go gages and no go gages are fixed limit gages with gauging limits based on the plus or minus tolerances of inspected parts. Minus pin gages normally found in sets can be anywhere between 0002 undersize to the nominal dimension and plus pin gages anywhere between nominal and 0002 oversize. Measure hole diameters calculatedistances between holes gageslot widths and locations.
I need to do some interference fits 1 4 for example. Eric m liked this post. All gages are uniformly 2 long with ground ends allowing you to use both ends for increased gage life. Those most commonly used are the minus pins.
Make quick and accurate measurements with vermont gage pin gages. These can be either plus or minus pins. Use for go nogo inspection. Set micrometers verniers and other measuring devices.
Likewise a plus pin gauge set includes pins with a specified tolerance above the target dimension creating a no go situation for a bore at the target dimension.

Plug and pin gages are used to compare hole and slot dimensions or locations to specific tolerances.
I took a quick look at availability and there are plus sets and minus sets. If super accuracy is required pin gages are available in 0001 increments. Therefore a 9998 gauge pin might be actual size but it is generally referred to as a 1 000 pin the size shown on the pin. If you re looking for a cheap passing grade quality set try enco.

A minus pin gauge set includes pins with a specified tolerance below the target size allowing the pin to fit within the target dimension. However plus minus pin gage sets each have their utility i think it s probably a wash. There are shars to starret to meyer in terms of cost and i assume quality.
