J&W strictly adheres to international quality standards in its production system. Raw materials undergo multiple rounds of testing before being used. The entire production process follows standardized operations, with comprehensive testing of the bolts' appearance, dimensional accuracy, and mechanical properties to ensure that every product stably fits the wheel hub and meets daily safe driving requirements.
We strictly control the quality and stability of raw materials from the source, and use statistical process control (SPC) technology to monitor the production process in real time. Finished products must undergo durability tests that simulate real vehicle conditions, such as fatigue tests and salt spray tests, to ultimately create high-quality bolts that are fatigue-resistant, corrosion-resistant, and have excellent fastening performance, ensuring long-term reliability.
