The dimension 25 H7 indicates a standard fit for a dimension. The fit is described using the basic size (25) and the fit designation (H7).
In this system, the "H" stands for the hole, and it represents the baseline or zero line in the fit system. The number that follows represents the tolerance range.
The "H" always corresponds to the basic size. So, for an H7 fit, the lower limit of the hole is the basic size, which is 25.00.
