        Introduction This article provides a comprehensive overview of metric thread major diameter tolerances, focusing on internal threads as per ISO 965 standards. It serves as an essential reference for engineers and manufacturers, detailing tolerance values and calculation methods to ensure compatibility and performance in mechanical assemblies. The content is derived from established industry standards, offering precise data for nominal sizes from M1 to M300. For broader context on metric threads including major, pitch, and minor diameters, refer to related standards such as ISO 68-1 and ISO 261. Understanding Metric Thread Diameters In metric threading systems, the major diameter (D for internal threads) represents the largest diameter of the thread profile.
