Application Summary AI generated
This standard specifies the maximum and minimum dimensional limits for metric trapezoidal screw threads, including major, pitch, and minor diameters. It is applied in the design, manufacturing, and quality inspection of lead screws, feed mechanisms, and power transmission components in machine tools and industrial machinery. The standard ensures interchangeability and functional fit between threaded parts used in precise linear motion systems.
