Application Summary AI generated

This standard specifies the tolerance system for buttress threads with 3° and 30° flank angles, defining permissible deviations for pitch, major diameter, and minor diameter. It is applied in the manufacturing and quality inspection of threaded components used in mechanical systems, such as lead screws, power transmission shafts, and heavy-duty fasteners, where high axial load capacity and precise fit are required. The standard ensures interchangeability and reliable performance in industrial machinery, including presses, jacks, and hydraulic equipment.
