Cold-Heading High-Strength Alloy Steel: Selected high-grade alloy steel is used as the base material and formed through an integrated cold-heading process, creating a dense internal grain structure with enhanced tensile and shear strength.
High-Precision CNC Thread Processing: CNC precision threading technology is applied to ensure accurate matching with wheel mounting holes, helping prevent thread binding and uneven engagement.
Multi-Layer Mirror Chrome Finish: Multiple electroplating and polishing processes create a dense protective layer that helps resist acid rain, road salt, and daily wear while maintaining a bright surface finish over extended use.
Advanced Corrosion Protection: The chrome-plated coating helps isolate oxidation factors, extending service life and providing reliable performance in harsh climates and challenging road conditions.
Precise PCD Compatibility: Designed for specific PCD (Pitch Circle Diameter) wheel bolt patterns, helping distribute fastening stress evenly and reduce the risk of loosening caused by uneven load concentration.
High-Load Fastening Reliability: The optimized balance of toughness and hardness provides stable torque retention during high-speed driving and frequent braking conditions.
High-Performance Modified Vehicles: Ideal for customized vehicles requiring both secure wheel fastening performance and enhanced wheel appearance.
Daily Off-Road & Performance Driving: Suitable for complex environments involving salt exposure, mud, and demanding road conditions, helping maintain long-term suspension and wheel system reliability.
Premium Wheel Upgrades & Replacement: Compatible with aluminum alloy and forged wheels for replacement installation, improving the overall visual quality and performance of the wheel area.
