          Introduction to Metric Thread Tolerances Metric screw threads, standardized under GB\/T 197 (equivalent to ISO 965), define tolerances for external and internal threads to ensure interchangeability and performance in mechanical assemblies. This guide focuses on external thread pitch diameter (d2) tolerances, which are critical for proper mating and load distribution. Tolerances account for manufacturing variations while maintaining functional fits, ranging from loose to tight depending on application needs. The standard specifies seven tolerance grades (3 to 9) for pitch diameters and eight fundamental deviation positions (a to h) for external threads, resulting in 56 possible combinations. With 349 thread specifications from M1x0.2 to M300x8, this yields extensive data sets.
