General tolerances

General tolerances are predefined acceptable limits for dimensions and measurements in manufacturing and engineering. They specify how much a produced part’s size or shape can differ from the exact specified measurement without affecting its function or quality. These tolerances provide standardized guidelines, helping ensure parts fit and work together properly, even if they slightly vary due to manufacturing processes. Essentially, they define a permissible range for deviations, allowing for consistent quality control while accommodating practical production variations.
