Application Summary AI generated

This standard specifies the limits of sizes for general purpose metric screw threads of coarse quality and the preferable plan. It is applied in mechanical engineering and manufacturing contexts where less precise threading is acceptable, such as for non-critical fasteners in construction, agricultural machinery, or temporary assemblies. The standard ensures interchangeability and basic fit control for threads not requiring high accuracy.
