This standard is a revision of GB/T 57851986, with the following major changes: a) two length specifications listed in Table 1 and Table 2; b) the degree of improvement of the method for the final optimization: Table 1: the optimization specifications (sample 1 should be noted in Table 1 and Table 2; Table 2: the optimization specifications (the values in Table 31 of the standard M20×1 are listed in Table 1 and Table 21); e) add 5.6 grade; d) add non-ferrous metal screws, the supply and demand parties shall agree on the best grade (Table 3); e) add powder microlayer (Table 3). This standard shall replace GB/T 5735198% from the date of implementation. This standard was proposed by the State Administration of Machinery Testing. This standard was approved by the National Quality Control and Standardization Technology Committee, and the standard was supported by the China Academy of Mechanical Science. Beijing Standard Parts Industry Group, Shanghai Screw Needle Factory, Biyang Standard Parts Manufacturing Factory and Zhejiang Xinggao High Strength Case Factory participated in the drafting. The National Quality Control and Standardization Technical Committee Secretariat of the ISO Foreword ISD (International Organization for Standardization) is a world-wide national standard ISO is a cooperative organization that is composed of standard bodies (ISO member bodies). The work of preparing international standards is carried out through various technical committees. Each member body is interested in the work carried out by a technical committee - ISO may participate in the committee. International organizations, governmental and non-governmental, with an interest in ISO may also participate in the work. ISO has a close joint project with the International Electrotechnical Commission (IEC) in the field of electrotechnical standards. The drafting of international standards shall be carried out in accordance with the rules given in Part 3 of the ISO Directives. The draft international standards adopted by the technical committee shall be returned to the International Standard. Distribution form all or member of the body to achieve the makeup ticket missing.
