What are tolerances as per DIN 2768 mk?

DIN 2768 mk refers to a standard in Germany that specifies tolerances for linear dimensions, particularly in mechanical engineering and manufacturing. It categorizes tolerances into different classes, ranging from very tight to coarse, depending on the precision required for specific applications. The standard helps ensure consistent quality and interoperability of components by providing guidelines on allowable deviations from specified dimensions. This is crucial for maintaining the functionality and fit of assembled parts.
