A car flange screw is a fastener with a flange (washer-like base) integrated into the head of the screw, enabling load distribution and anti-loosening functions without the need for additional flat washers. The flange face design increases the contact area, effectively preventing loosening caused by vibration, making it particularly suitable for high dynamic load environments such as automobiles.

Core Advantages:

• Excellent anti-loosening performance: The flange face provides radial anti-slip teeth, maintaining secure fastening stability under high-vibration conditions (such as engines and transmissions).
• Uniform load distribution: The integrated flange effectively disperses clamping force, avoiding damage to the surfaces of connected components.
• High assembly efficiency: Eliminates the step of installing separate washers, reducing assembly time and error rate.
• Compact structure: Especially suitable for connecting automotive components with limited space.
