A central feature of the ANSI B92.1-1996 standard is the "effective fit" concept, which accounts for the combined effects of profile errors, tooth spacing variations, and eccentricity. This approach ensures that the "effective" tooth thickness (or space width) takes precedence over the actual measured dimensions during assembly. The standard sets the minimum effective space width and maximum effective tooth thickness to be of equal value for side fits, providing a reliable baseline for mating parts. master2000
