【OEM Certification Standards】 Strict adherence ISO/TS 16949 quality management system. Each bolt undergoes torque testing, fatigue testing, and validation to ensure perfect compatibility with wheel hubs and braking systems.Made from premium alloy steel or titanium alloy, processed through heat treatment to enhance hardness and tensile strength, ensuring durability under high-speed driving and extreme road conditions without deformation.
【Precision Thread Design】 CNC precision-machined threads combined with anti-loosening structures (e.g., conical seats or flange surfaces) effectively prevent bolt loosening caused by vibrations, enhancing driving safety.
【Anti-Corrosion Coating Technology】 Multi-layer rust-resistant coatings (e.g., zinc-nickel alloy or Dacromet coating) provide resistance to salt spray and corrosion, adapting to harsh environments like humidity and snowy roads while extending service life.
