Duplex hex nuts are specialized fasteners featuring a dual-layer design and a hexagonal exterior, making them ideal for applications requiring reliable fastening, stable positioning, and high assembly efficiency. Their hexagonal shape facilitates installation and removal using standard tools, and they can be customized to meet specific thread specifications, dimensions, and material requirements. Manufactured from high-quality steel, stainless steel, or other suitable metals, these nuts undergo precision processes—such as cold heading, turning, threading, heat treatment, and surface finishing—to ensure dimensional accuracy, superior mechanical properties, and excellent corrosion resistance. Widely used in automotive wheel hubs, machinery, industrial assembly, and various threaded connection systems, they cater to the diverse needs of different vehicle models, equipment types, and installation environments. We offer customization, OEM/ODM services, sample validation, and volume supply, delivering consistent product quality and professional service to our customers.
