Hex Bolts 07149126886 For BMW E81 F20 F22 F45 F46 F22 F87 F34

Hexagon bolts for automobile heat insulation panels need to have the following properties:

1. High-temperature resistance: The heat insulation board is usually located near the engine, which will be affected by high temperature. Therefore, the hexagon bolt used for the heat insulation board of the automobile needs to have good high-temperature resistance and can work stably for a long time in a high-temperature environment without failure.

2. Corrosion resistance: The heat insulation board may be affected by the corrosion of engine exhaust gas, so the bolt needs to have good corrosion resistance, be able to resist the corrosion of chemicals and maintain the stability and reliability of the connection.

3. High strength and hardness: the heat insulation board will be subjected to vibration and impact during the running of the automobile, so the bolts need to have sufficient strength and hardness to bear the force between the connectors to ensure the firmness and stability of the connection.

4. Good sealing performance: The insulation board needs to be closely connected with other parts, so the bolts need to have good sealing performance, which can prevent gas or liquid from leaking and keep the insulation board in normal working condition.

5. Convenient installation and disassembly: The insulation board may need to be replaced frequently in the process of automobile maintenance, so the bolt should have the characteristics of convenient installation and disassembly, and it can be easily operated by a wrench or wrench sleeve to improve work efficiency.

To sum up, the hexagon bolts used in automobile heat insulation panels need to have high temperature resistance, corrosion resistance, high strength and hardness, good sealing performance and convenient installation and disassembly, so as to ensure the stability, safety and reliability of the connection between heat insulation panels and other components.
