If super accuracy is required, pin gages are available in ." increments. Minus pin gages normally found in sets can be anywhere between ." undersize to the nominal dimension and plus pin gages anywhere between nominal and ." oversize. Every pin that I have checked has been ." undersize or oversize but that is not a universal given.
If you really want to get in tight, both minus and plus pins would be desirable.If you were trying to verify a ." hole with pin gages that were exactly nominal, you would not be able to insert the .250" pin. All you could say was the hole was greater than .249" and less than .251". A .250" minus pin would enter a .250o" hole and a .250" plus pin would not. If I could only afford one set, I would get the minus pins.

Plug or Pin gauge sets act essentially as a go no go gauges, and are used for verifying the diameter or holes and slots. They are used to quickly determine whether or not hole sizes are within tolerance. Typically pin & plug gauges are made of hardened steel or tungsten carbide, and come in sets containing various sizes to allow for a wide range of measurement. They are available in Class XX, X, Y, Z, and ZZ tolerance standards, with Class XX having the tightest standards.

A pin gauge set will typically consist of either plus or minus pin gauges, and based on procedure or tolerances may require both versions to determine a go no go outcome. A minus pin gauge set includes pins with a specified tolerance below the target size, allowing the pin to fit within the target dimension. 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.
