We specialize in the development and manufacturing of custom-made special nuts and fittings based on customer drawings and specifications.    

The automotive industry has been at the core of our business for decades.Our journey began in 1997 with a stainless steel battery terminal nut supplied to a GM vehicle program through a Taiwanese trading company and a Japanese customer. This project marked our first step into the automotive fastening industry and laid the foundation for our long-term commitment to automotive quality and manufacturing excellence.In 2007, we achieved ISO/TS 16949 certification, the predecessor of today's IATF 16949 quality management system. Since then, automotive components have become our primary business focus.Today, approximately 90% of our products are supplied to automotive-related applications, covering hydraulic systems, cooling systems, anti-loosening solutions, structural assemblies, and customer-specific fastening components.With decades of experience, we continue to support global automotive supply chains through reliable manufacturing, engineering expertise, and consistent product quality.

We specialize in the manufacture of stainless steel nuts through warm forming combined with precision secondary operations.Our stainless steel production lines utilize dedicated wire pre-heating systems to enhance material formability, enabling a well-balanced combination of product quality, manufacturing efficiency, and cost competitiveness. With over 30 years of experience in stainless steel forging technologies, we have continuously refined our manufacturing processes to ensure reliable quality and long-term production stability, even for demanding stainless steel grades. Our stainless steel fastening nut products are widely applied across industries such as automotive, aerospace, green energy, and hydraulic systems, where strength, corrosion resistance, high-temperature performance, and reliability are critical.

Aluminum alloy offers excellent lightweight performance, corrosion resistance, and flexible surface finishing options, making it suitable for applications where weight reduction, protection against environmental exposure, electrical functionality, or decorative appearance are required. Brass combines corrosion resistance, electrical conductivity, good machinability, and non-magnetic properties, making it an ideal material for precision fastening components.

We manufacture a variety of locking nuts designed to prevent self-loosening under vibration and dynamic loading conditions.Depending on the design, the locking function may come from an all-metal prevailing-torque feature, a nylon insert, or another customer-specified locking structure. 

Weld nuts are one of the most fundamental fastening components used in welded assemblies.  The concept itself is simple and has played an important role in structural and industrial assemblies where reliable threaded connections are required within welded structures. Most of our weld nut production is based on customer drawings, reflecting a mature engineering component where reliability, consistency, and innovation are equally valued in maintaining long-term performance.

Flare Nut is designed for hydraulic and pneumatic tube fitting systems requiring high sealing reliability, dimensional accuracy, and stable mechanical performance.Our flare nuts are produced in accordance with DIN 3870 Type A3 standards, with customer-specific design adjustments available to meet precise assembly requirements.We also have the capability to develop SAE J514 CAP nuts, supporting SAE JIC 37° flare fitting systems for industrial tubing applications.

Special T nuts are manufactured according to customer drawings and specifications, reflecting a fully customized production approach. Rather than being limited to one standard T-shaped configuration, a custom T Nut can be developed according to the mating component, installation method, available space, and required load or retention function. Thread dimensions, flange geometry, body length, outside profile, and secondary features can be adjusted according to the application.

We specialize in manufacturing flange nuts based on customer drawings and specifications.

Reliable clinch nut performance is achieved through shared technical understanding between manufacturer and user—from design to installation.
