Its form resembles traditional metal fasteners, available in various configurations such as bolts, nuts, screws, and studs to accommodate diverse connection requirements. | | Specifications | Diverse dimensional options available for custom production based on project requirements. Thread specifications, length, diameter, and other parameters can be flexibly adjusted to accommodate different assembly scenarios. | | Excellent Thermal Stability | Features an extremely low thermal expansion coefficient, resulting in minimal dimensional changes under extreme temperature fluctuations. This ensures connection precision and stability while reducing loosening or deformation caused by thermal expansion and contraction. This property is particularly critical in precision instruments and equipment demanding high dimensional accuracy. | | Corrosion Resistance | Exhibits outstanding resistance to most acids, alkalis, salts, and other chemicals. Maintains stable performance and extended service life in harsh chemical environments where metal fasteners often corrode. | | Excellent Tribological Properties | Features a low coefficient of friction and superior wear resistance. Reduces wear and friction-induced heat in moving joints, lowering maintenance costs and failure risks. | | Automotive Industry | Particularly in high-performance racing vehicles and new energy vehicles, these fasteners can be used for critical connections in engines, braking systems, and other key components. They reduce vehicle weight while enhancing power performance and handling. Their high-temperature resistance also makes them suitable for connections in high-heat areas like engine compartments. | | Energy Sector | In nuclear fusion reactors, carbon-carbon fasteners connect and secure internal high-temperature components, withstanding radiation and thermal loads from high-temperature plasma. In the solar photovoltaic industry's silicon wafer manufacturing process, they connect components within high-temperature furnaces, ensuring stable equipment operation under extreme heat. | | Category | [Hex & Other Standard Nuts](https://engineeringhardware.com/fastener-products/nuts/hex-other-standard-nuts/) | ## Technical parameters | Carbon-Carbon Fasteners | | | | | --- | --- | --- | --- | | Material | Carbon-Carbon Composite Materials | Certification | ISO9001 | | Density | 1.4–1.6 g/cm³ | Compressive Strength | 120~160/Mpa | | Thermal Conductivity | 50–110 MPa | Flexural Strength | 100~150/Mpa | | Advantages | Good toughness/High temperature resistance /Corrosion resistance/Good thermal shock resistance | Application Areas | Suitable for the thermal fields of various high-temperature furnaces | | Stock | Store in a dry environment | Transport Packaging | Standard Wooden Packaging | | Specifications | Available upon request | Temperature | | | Country of Origin | Shandong, China | Production Capacity | 100,000 pieces/month | ## Description Source Factory Customizes Various Types of Nut Fasteners is part of our hex & other standard nuts range (Nuts). ### Key details - **Type:** Square Head - **Standard:** GB - **Material:** Carbon Fiber Composite Material - **Grade:** 8.8 - **Head Style:** Square - **Connection:** Common Bolt - **Certification:** ISO9001 - **Temperature:** High-Temperature Resistant Available configurations include material, head style, standard, grade and package size.
