Application Summary AI generated

This standard specifies the M (span measurement over pins) and W (span measurement over teeth) values for straight cylindrical involute splines with a 30° pressure angle. It is applied in the design, manufacturing, and inspection of mechanical transmission systems, such as automotive drivetrains, machine tools, and aerospace components, to ensure correct gear tooth geometry and fit. Engineers and quality control personnel use these values to verify spline dimensions during production and assembly.
