GB/T 9144-2003 Ordinary thread preferred series

This standard specifies the preferred series of common threads. This series is selected from the standard series of common threads specified in GB/T193-2003, and its nominal diameter range is 1mm to 64mm.

This standard adopts 150262:139150 (GB/T9144-2C03, city nail, inspection and depth of the selected English code). There is a technical difference between our country's standard and ISO standard. The two standards have different marking names. The application scope of the standard defined by the ISO standard is too narrow and cannot accurately express the application scope of the standard. According to the technical memory specified in Chapter 1 of the IS core standard (the specification uses the standard name that can reflect the actual application of this standard: GI147U1-1953 screw effect terminology and S02, the frequency pattern technology may be different, the media effect is divided into the national plastic screw effect: the non-time source pattern on the close bleaching pattern: the mechanical source and the transmission screw effect: the tooth vertical refining effect and the asymmetric thermal pattern, currently I51) three B standards only promote the original example grade (part of the protection of the solid and part of the goods selling the screw terminology, follow it without satisfaction In order to meet the actual production needs, my country has followed the example of many countries such as the United States, the United Kingdom and Russia, and has formulated a relatively comprehensive standard for thread terminology, that is, the technical content of my country's thread terminology standard is more comprehensive, and it contains more technical content than the thread technical standard.
This standard is the standard for the common series of standards in the fire-resistant series. The common thread series includes GB/192--2033 common thread basic tooth type 3B/T103-2393bzxZ.net

This standard specifies the use of a series of metric lithium wires with a sealing agent. This series is selected from the modified standard series specified in G/1138-2003: its nominal actual diameter is 1m--4mm, this standard is not suitable for screw, butterfly and time, and is suitable for washable and preferred series of threads , 2 Normative referenced documents
