National standard for tightening nuts and standard size of nuts
Standard size for fastening nuts
1 Scope This standard: specifies the tightening nut (referred to as the nut), the size of the locking device, technical requirements, acceptance rules and measurement methods. This standard applies to the design, production, inspection and user acceptance of nuts and locking devices for tapered bushings.
2 Reference Standards: The provisions contained in the following standards constitute provisions of this standard by reference in this standard. At the time of publication, the editions indicated were valid. All standards will be revised and parties using this standard should explore the possibility of using the latest version of the following standards. GB/T 192—1981 Ordinary thread basic tooth type GB/T 196-1981 Ordinary thread basic size (diameter 1~600 mm) GB/T 272-1993 Rolling bearing code method GB/T 699-1988 Technical condition of high quality carbon structural steel GB/T 1804—1992 General tolerances Linear dimensions of unfilled tolerance GB/T 2516—1981 Ordinary thread deviation table (diameter 1~355 mm) GB/T 5796.1—1986 Trapezoidal thread type GB/T 5796.3—1986 Trapezoidal thread basic Dimensions GB/T 5796.4—1986 Trapezoidal thread tolerance GB/T 6930—1986 Rolling bearing vocabulary GB/T 8597—1988 Rolling bearing package JB/T 3574—1997 Rolling bearing product mark JB/T 8921—1999 Rolling bearing and its commodity parts inspection rules.

3 Terminology: The terminology used in this standard complies with the provisions of GB/T 6930.
This standard specifies the marking system, indicators, test methods and signs for the mechanical and working performance of effective torque steel hexagonal lock nuts. This standard is applicable to coarse-toothed 6H-grade nuts made of carbon steel or alloy steel with a width of 3 to 39 mm and a nominal height of ≥0.8D and a required guaranteed load and effective torque. In addition to the effective torque part, the thread size and tolerance are in accordance with GB 193, GB 196 and GB 197. The working temperature range of the nut should be: all metal nuts without electroplating: -50 °C ~ +300 °C. All metal nuts treated by electroplating: -50 °C ~ +230 °C Nuts embedded in non-metallic components: -50 °C~+120°C This standard does not apply to nuts with special performance requirements (such as welding performance and corrosion resistance). For fine-tooth lock nuts or thin nuts made of carbon steel or alloy steel of stainless steel and non-ferrous metals, the performance index and test method of effective torque specified in this standard may be adopted by both parties.
