What does 'BSC' mean in datasheet dimensions?

In many datasheets, you can find dimensions like 6.00 BSC and in most datasheets, it is not defined what BSC means.

BSC means that this value is given without tolerancesas a value which is exact (at least in theory). In practice of course, the dimension will have some tolerances, but these tolerances are not given in the datasheet.
