Our M14x1.5 ball seat wheel lug bolts are manufactured in strict accordance with GB/T 196-2015 national standards. The precise thread pitch and angle ensure smooth, tight engagement with matching wheel hubs, effectively reducing assembly errors and avoiding loose connection problems during long-term vehicle operation.
The exclusive ball seat design perfectly fits the curved mounting surface of automotive wheel hubs. It evenly disperses driving vibration and mechanical stress on the connection position, significantly improving overall driving stability and preventing wheel deviation or shaking during high-speed driving.
Selected high-quality automotive-grade base materials are adopted for production, which perfectly balances structural hardness and mechanical toughness. The bolts can withstand long-term road vibration, impact pressure and load changes, avoiding fracture, deformation and other common failures of inferior fasteners.
Equipped with an automatic electroplating production line, the product surface forms a uniform, dense protective layer. It effectively resists rust, oxidation, and erosion from rain, snow and road salt spray, adapting to various complex road and weather environments and extending service life greatly.
With standard M14x1.5 thread specification and universal ball seat interface, the lug bolts are compatible with most mainstream passenger and commercial vehicle models, meeting diverse usage scenarios of factory assembly, after-sales replacement and wheel modification.
Supported by 12 large cold heading machines and over 20 precision machining centers, our products feature compact internal structure and no internal porosity or defects. Precision CNC machining controls dimensional errors within industrial optimal ranges, ensuring consistent product accuracy for every batch. The fully automatic electroplating line guarantees uniform surface treatment and stable overall quality.
We implement comprehensive quality supervision from raw material procurement to finished product delivery. All raw materials are strictly screened and tested to meet automotive fastener industry standards. Real-time dimensional monitoring is carried out during production, and finished products undergo tensile strength, wear resistance and 72-hour salt spray tests to verify comprehensive performance.
Standardized production specifications realize excellent product interchangeability. The m14x1.5 wheel locking ball bolts can be directly used for OEM factory supporting assembly, auto repair shop replacement and personalized wheel upgrade modification, covering most mainstream vehicle models in the market with high applicability.
Covering a 10-acre factory area with mature automated production lines and standardized 5S management mode, our factory has stable mass production capacity. We can efficiently meet global small-batch customized orders and large-batch bulk orders with stable delivery cycles.
