Preface
GB/T 6182 is one of the national standard of "hexagonal locking nut" series, which includes.
--- GB/T 889.1 type 1 non-metallic insert hexagonal locking nut;
--- GB/T 889.2 type 1 non-metallic insert hexagonal locking nut fine teeth;
--- GB/T 6172.2 Hex Locking nuts with non-metallic insert;
--- GB/T 6182 type 2 non - metallic insert hexagonal locking nut;
GB/T 6183.1 Type 2 non - metallic insert hexagonal flange face lock nut;
--- GB/T 6183.2 Type 2 non-metallic insert hexagonal flange face lock nut fine teeth;
--- GB/T 6184 type 1 all-metal hexagonal locking nut;
--- GB/T 6185.1 Type 2 hexagonal locking nuts with all metal;
--- GB/T 6185.2 Type 2 All-metal hexagonal locking nut fine teeth;
--- GB/T 6187.1 Type 2 all-metal hexagonal flange lock nut;
--- GB/T 6187.2 Type 2 All-metal hexagonal flange nuts.
This standard is drafted in accordance with the rules given in GB/T 1.1-2009.
This standard replaces GB/T 6182-2010 "Type 2 non-metallic insert hexagonal locking nut", compared with GB/T 6182-2010, the main
The technical changes are as follows.
--- Delete "For other technical requirements, such as GB/T 3098.9 and GB/T 3103.1)." (2000 edition 1
chapter);
--- reference thread standard unified GB/T 193, GB/T 9145 (Chapter 2);
--- Mechanical performance grade modified as. 10 (QT), 12 (QT) (Table 2);
--- mechanical properties increase. QT --- quenching and tempering (Table 2);
- Added reference in mechanical performance standards GB/T 3098.2 (Table 2);
--- increase the surface without treatment, remove the oxidation treatment (Table 2).
This standard uses the re-drafting method to modify ISO 7041..2012 "2-type effective torque hexagon nut (non-metallic insert) performance
Level 9 and 12 "(English version).
The technical differences between this and ISO 7041..2012 and the reasons are as follows.
- remove ISO 7041. "For other technical requirements, ISO 2320 and ISO 4759-1." (Chapter 1)
Does not belong to the provisions of this standard;
- in the reference document, with our standard instead of international standards (Chapter 2), to increase the reference GB/T 6175 (Chapter 1),
GB/T 90.2 (Table 2) and GB/T 1237 (5.1), the deletion of references to ISO 724 to meet the basic standards of fasteners in China;
--- According to our practice recommended nylon 66 (Table 2);
--- Mechanical performance grade modified as. 10 (QT), 12 (QT) (Table 2), improve the technical conditions;
--- To carry out the basic standards, mechanical properties increase. QT --- quenching and tempering (Table 2);
--- to increase the packaging technical requirements (Table 2) to meet the basic standards of China's fasteners;
--- Example of a modified mark is a simplified example of a mark (5.2) to comply with the requirements of GB/T 1237.
This standard also made the following editorial changes.
--- modify the standard name;
--- remove the ISO 7041 reference bibliography.
This standard is proposed by the China Machinery Industry Federation.
This standard is nationalized by the National Standardization Technical Committee on Fasteners (SAC/TC85).
This standard is responsible for drafting units. China Machine Productivity Promotion Center.
This standard participated in the drafting unit. Zhoushan City is the source of standard parts Co., Ltd., machinery industry, general parts and components product quality supervision and inspection center,
Ningbo Zhongji Machinery Parts Testing Co., Ltd.
This standard is interpreted by the Secretariat of the National Standardization Technical Committee for Fasteners.
This standard replaced the previous version of the standard release.
