This standard specifies the limit sizes of the middle diameter and top diameter of medium-precision, preferred series common threads based on the basic deviations and tolerances of GB/T9144-2003 and GB/T197-2003. The basic tooth profile of common threads conforms to the provisions of GB192-2003 and is suitable for general-purpose mechanical fastening threaded connections. The threads themselves do not have a sealing function.

This standard is amended as follows: 521993130—Metric ticket making - Part 2, Medium precision, Limits of internal and external screws (English version). There is no technical difference between the standard and the 1st standard. The names of the two standards are slightly different. The name of the TS standard does not specify what kind of specification is listed (standard, special or optional). According to the provisions of the 1st international standard (Fan Shang), my country's standard name "Excellent Series" qualifier. In addition, this standard also corrects a technical error in the 5th standard, and changes the 1st paragraph of the 1S door cup pot to "small should exceed the basic technical model" to "large actual model that does not exceed the position of the tolerance band of the standard" (this standard chapter). The ISO standard has considered the existence of basic differences.
G3/1471:-1693 Media Technology 12)508: 18 Examples of social media that are more local 5: Single effect can be divided into four-dimensional effect and screw effect: sealing pattern and non-sealing pattern: tightness and transmission pattern, symmetrical tooth type and asymmetrical tooth type, recently) 51 standard only stipulates the difference between the return column ticket pattern (part of the machine lacks solidification pattern and part of the transmission explosion effect). The terminology, the machine plan light decision wine is sufficient to show the use demand of non-production. my country has formulated the three main types of fuel efficiency terminology standards with reference to the collection methods of countries such as Japan, the United States, and the United States: that is, the technical content of my country's frequency efficiency terminology standards However, it has included the technical content of the technical source standard of the general TS course.
This standard replaces the medium auxiliary standard (1/914-198% of the commodity model), and the size range of the wood standard is standardized compared with GB/T91451SB. The nominal diameter of the new thread in the old standard is 42-69 mm (the nominal diameter is 42-69 mm) and the nominal diameter is 4-64 mm (the reference part is included in the appendix A). The nominal size range of the wood standard is 64 mm. The wood standard is not a small standard in the core size of the standard series.

The terms and definitions specified in GB[14791] apply. 1 Screw sensitivity mark
Screw grade marking method see 1/F197-2, Part 3, 5 Limit size
The maximum physical tooth on the wheel that cannot be detected by supersensitivity is the maximum physical tooth on the wheel that cannot be detected by supersensitivity. If there are no other special instructions, the tolerance notice applies. After the mirror, the actual wheel thread should not be adjusted. According to the tolerance band, the maximum size of the actual body is as follows: Note: The tolerance book has the following effective internal source, for example, 5.1 internal thread
tolerance: only:
degree of engagement: medium,
tolerance band: G male you directly small and other ten 1.4; 6 male you white diameter one.am.
