AbolishedGeneral purpose metric screw threads--Limit deviations
普通螺纹 极限偏差
Application Summary AI generated
This standard specifies the limit deviations for general purpose metric screw threads, defining the permissible variations in pitch, flank angle, and thread diameter for tolerance classes 4H through 8H (internal) and 4h through 8h (external). It is applied in the design, manufacturing, and quality inspection of threaded fasteners and components across mechanical engineering, automotive, and industrial equipment sectors to ensure interchangeability and proper fit. The standard is used as a reference for thread gauging and acceptance testing in production and assembly environments.
