HomeApplying ISO 2768 Tolerances in Manufacturing
Jan 22,2025 
ISO refers to the International Organization for Standardization. It is a set of internationally agreed guidelines that help industries to work in a consistent way. The guidelines are standardized measurements, for example about quality, safety, environment, energy, health and many more. It ensures that products, services, operations or environment are safe, good quality and trustworthy. ISO 2768 is one of them which defines mechanical tolerance. This article provides more information about the guidelines, their significance in manufacturing and other important aspects.
What is ISO 2768? Explained
ISO 2768 standard defines the tolerance of mechanical parts. It identifies different levels and types of tolerance of parts.
Overview of ISO 2768 Standard
ISO 2768 defines general mechanical tolerances in engineering drawings. It defines standardized measurements for linear, angular, and geometrical measurements. In manufacturing, ISO2768 is utilized in simplifying designs and production. It is used particularly for those components which do not require high precision machining
What is the Significance of ISO 2768 in Manufacturing?
In manufacturing, it helps in defining linear, angular measurements of part. It also defines geometrical tolerances for designs that lack individual tolerance specifications. It offers a structure to achieve acceptable precision machining. It also reduces inconsistencies while comprising manufacturing costs
Is ISO 2768 Still Valid Today?
Yes, it is still valid today and is one of the globally recognized standards. It is commonly used for identifying tolerances for linear and angular measurements in engineering drawings
ISO 2768-mK: Meaning and Importance
ISO 2768-mK is a subset standard of 2768. This standard explains tolerances for linear and angular dimensions.
What is ISO 2768-mK?
In ISO 2768-mK, M represents medium tolerance, and K represents tolerance class for features such as chamfer heights and external radii.

ISO 2768-mK vs ISO 2768: Key Differences
It is the standardized measurements for tolerance values for linear, angular dimensions. While ISO 2768-mK is its subset. It defines medium tolerances for geometrical features. The major differences lie in tolerance class, and the areas where these standards focus like ISO2768 is generic while ISO 2678-mK focus on medium tolerance and the applications. ISO 2768 applies for manufacturing metal and plastic parts. And ISO 2768-mK is for designing components
What is the Difference Between ISO 2768-1 and ISO 2768-2?
The differences between these two standards are discussed below:
ISO 2768-1: Tolerances for Linear and Angular Dimensions
The main purpose of ISO 2768-1 is to simplify the drawing and to avoid writing tolerance in each dimension. For example, for linear dimensions it explains external and internal sizes, Dia or radii. For angular dimensions it explains angles
ISO 2768-2: Geometrical Tolerances for Features
ISO 2768-2 also simplifies drawings. It specifies general tolerance for straightness, flatness, circular, and cylindrical parts. It is usually used for chamfer and radius tolerance created by removing material
