When a drawing references "ISO 2768-mK," it implies that any dimension or geometric feature not explicitly tagged with a specific tolerance falls under these "general" rules. This significantly de-clutters the drawing, highlighting only those features requiring precise control.
These values are symmetric (±), meaning the deviation is allowed equally above and below the nominal size. This symmetry is ideal for fits where the clearance or interference is not critical. ıso 2768 mk
For linear dimensions (lengths, diameters, step heights, radii, and chamfers), "m" stands for —the most commonly used precision level. It strikes a balance between cost and accuracy for typical machined parts. When a drawing references "ISO 2768-mK," it implies
