  • R&D Capabilities
    We have over 30 years of R&D experience in automotive fasteners, covering strength grades, tolerance accuracy, surface corrosion resistance, and temperature performance, along with MAT self-correcting thread technology.
  • Manufacturing Capabilities
    We have a complete production system for flange nuts, welding nuts, and other automotive fasteners and stamping parts, with over 500 product varieties. From raw materials to finished products, every step is strictly controlled.
  • Quality Control
    We are certified to IATF 16949-2016. Each process undergoes rigorous quality inspection to ensure every product meets the quality standards of mid-to-high-end auto parts.
Strength Upgrade: Breakthrough in High-Grade Nuts
From early Class 5/8 to the current development of Class 12, and successful pre-research of Class 13–14 ultra-high-strength nuts, our products can now withstand greater axial loads, making them suitable for heavy-duty trucks and high-performance engines.

    Proprietary Technology: Self-Correcting Thread
    Our MAT thread nut features a unique self-correcting function on its first few threads. During automated assembly, even with minor misalignment between the bolt and nut, the nut guides the bolt into the correct thread path, improving assembly efficiency.
