Abstract
It is pointed out that the definition of fit tolerance in GPS national standard GB/T1800.1-2020 and related knowledge systems does not reflect the essential attributes of the concept.Based on the in-depth analysis of the fit between hole and shaft,the essential attribute of the concept of fit tolerance is revealed,and the definition of fit tolerance is reformulated to reflect the connotation of fit tolerance more deeply.
