In this paper, the advancedness and adaptability of 1973 ГОСТ standard, the relationship with the old standard of the company, the limitations of the old standard and the information provided by the manual are compared and analyzed from the thread tolerance grade and the location of the tolerance band. Through comparative analysis, the equivalent of ГОСТ cutting thread blank size standards, can fully meet the new thread nominal diameter, pitch series and all the optional use of the provisions of the tolerance range of thread processing; can also be cut out of qualified thread. But also truly reflects the superiority of adopting the new thread standard that is equivalently adopted.
