This guide provides a detailed overview of China M6 hex bolts, covering their specifications, materials, applications, and sourcing options. We'll explore different grades, surface treatments, and considerations for selecting the right bolt for your project. Learn how to identify quality M6 hex bolts and find reliable suppliers.
The M6 in China M6 hex bolt refers to the metric size, indicating a nominal diameter of 6 millimeters. Other crucial specifications include bolt length, thread pitch, and head height. These dimensions are standardized according to international standards like ISO 4017, ensuring interchangeability between different manufacturers. Understanding these specifications is crucial for proper selection and application.
China M6 hex bolts are available in various materials, each possessing different strength and corrosion resistance properties. Common materials include carbon steel (various grades like 4.8, 8.8, 10.9), stainless steel (304, 316), and alloy steel. The grade number indicates tensile strength; higher numbers signify greater strength. For instance, an 8.8 grade bolt is significantly stronger than a 4.8 grade bolt. Choosing the right material depends on the application's specific requirements and environmental conditions.
| Material | Grade | Tensile Strength (MPa) | Applications |
|---|---|---|---|
| Carbon Steel | 4.8 | 400 | General purpose |
| Carbon Steel | 8.8 | 800 | High-strength applications |
| Stainless Steel 304 | - | - | Corrosion-resistant applications |
Surface treatments enhance the durability and corrosion resistance of China M6 hex bolts. Common treatments include zinc plating (yellow or clear), hot-dip galvanizing, and black oxide coating. The choice of surface treatment depends on the intended environment and the desired level of protection. For example, hot-dip galvanizing offers superior corrosion protection compared to zinc plating in highly corrosive environments.
When sourcing China M6 hex bolts, it's crucial to choose a reliable supplier. Reputable suppliers adhere to strict quality control procedures and provide certifications to verify material properties and dimensional accuracy. Look for suppliers who offer a wide range of products, competitive pricing, and excellent customer service. Check for certifications like ISO 9001, which demonstrates a commitment to quality management systems. Thoroughly inspect the bolts upon delivery to ensure they meet the required specifications.
