This comprehensive guide explores the China G2130 standard for fasteners, detailing its specifications, applications, and significance in the manufacturing industry. We'll cover key aspects to help you understand and utilize this crucial standard effectively. Learn about the differences between G2130 and other fastener standards, and discover resources for ensuring compliance.
The China G2130 standard, officially known as GB/T , outlines the specifications for various types of mechanical fasteners. This standard is vital for ensuring quality, consistency, and interchangeability within China's manufacturing sector. It covers a wide range of fastener types, including bolts, screws, nuts, and washers, specifying dimensions, materials, performance requirements, and testing methods. Understanding China G2130 is critical for anyone involved in the design, manufacturing, or sourcing of fasteners in China.
China G2130 specifies various materials permitted for different fastener types, ensuring suitability for various applications. Common materials include carbon steel, alloy steel, stainless steel, and non-ferrous metals. The standard details the required chemical composition and mechanical properties for each material grade.
Precise dimensional tolerances are crucial for proper fit and functionality. China G2130 provides detailed dimensional specifications, including tolerances for diameter, length, thread pitch, and head dimensions. Adherence to these tolerances is essential for ensuring interchangeability and preventing assembly issues.
The standard also outlines performance requirements, such as tensile strength, yield strength, and fatigue resistance. These requirements are crucial for ensuring that fasteners can withstand the stresses and loads encountered in their intended applications. Testing methods are specified to verify compliance with these performance criteria.
China G2130 defines the thread profiles for various fastener types, including metric and other commonly used thread forms. Correct thread profile is critical for ensuring proper engagement and preventing stripping or damage during assembly.
While China G2130 is a widely used standard within China, it's essential to understand its relationship with international standards like ISO and ANSI. Understanding these differences is critical for global trade and collaboration. This often involves checking for equivalence and potential compatibility issues.
| Standard | Region | Key Differences |
|---|---|---|
| GB/T (China G2130) | China | Specific to Chinese market; may have variations compared to international standards. |
| ISO 898-1 | International | Widely adopted internationally; may offer greater interchangeability. |
| ANSI B18.2.1 | USA | Used predominantly in the United States; may have differing dimensions and tolerances. |
Compliance with China G2130 is crucial for manufacturers and suppliers. This requires rigorous quality control measures, including thorough material testing, dimensional inspection, and performance verification. Working with a reputable supplier who understands and adheres to the standard is also vital.
