By comparing and analyzing the common thread GB standard and ГОСТ ordinary thread standard, the main features and differences of the two kinds of standard are introduced briefly. Through the concrete analysis and contrast of the 5H6H tolerance band in the two standards, it is concluded that a certain type of engineering product The 5H6H tolerance band required by the ГОСТ standard in design drawings and workmanship is replaced by the 5H6H tolerance band for GB common thread.
