Product Introduction 9930640010-B Rear Wheel Nut Lock is a key fastener component for the rear wheel hub of HFC6800 vehicles. It locks the rear wheel nut tightly to prevent loosening caused by continuous vibration during long-distance driving and heavy load operation. This aftermarket replacement hardware eliminates safety hazards brought by loose wheel nuts, stabilizes wheel assembly operation and reduces the risk of wheel falling off on bumpy roads.
Product Advantages Fabricated from premium high-strength alloy steel with precision thread cutting, offering excellent locking capacity. Multi-layer anti-rust surface treatment resists corrosion from rain, mud and road salt. The self-locking structure maintains clamping force under persistent vibration and impact. Every unit passes thread tolerance inspection before shipment to ensure perfect fitment and reliable fastening performance.
