Application Summary AI generated

This standard specifies the tolerance system for metric trapezoidal screw threads, defining permissible deviations for pitch, flank angle, and major/minor diameters. It is applied in the manufacturing and quality inspection of lead screws, power transmission screws, and adjustment mechanisms in machine tools, lifting equipment, and industrial machinery where precise axial positioning and load-bearing threads are required.
