In the context of a go/no-go gage setup, the correct sizes of gage pins are determined by the given dimension and its tolerances. The dimension specified is 3/32 inches, which is equivalent to 0.09375 inches. The tolerance of ± 1/64 inches adds a range to this dimension.

Calculating the upper and lower limits:

  • The upper limit is 3/32 + 1/64:

3/32 = 6/64, so

6/64 + 1/64 = 7/64, which converts to approximately 0.109375 inches.

  • The lower limit is 3/32 - 1/64:

3/32 = 6/64, so

6/64 - 1/64 = 5/64, which converts to approximately 0.078125 inches.

In a go/no-go gage setup, the gage pin that is used for the "go" side must be at or just below the upper limit (0.109375), while the "no-go" pin must be at or just above the lower limit (0.078125).
