We specialize in non-standard special-shaped bolts and custom shaped nuts, accepting customer drawings and samples for personalized customization to meet unique assembly requirements. Our high-strength nuts are manufactured via precision cold heading process, using premium carbon steel and alloy steel materials—boasting excellent mechanical properties, high tensile strength, good toughness and wear resistance, ensuring reliable performance in heavy-duty applications. The round nuts cover 14P-24P specifications, with precisely processed internal threads for tight fitting and strong anti-loosening ability, suitable for bearing fixing, mechanical equipment locking and shaft end positioning. All non-standard (special-shaped) components undergo strict design optimization and quality testing, ensuring dimensional accuracy, structural stability and compatibility with matching fasteners. Widely applied in mold manufacturing, automation equipment, engineering machinery, automotive parts and special equipment assembly. We support flexible customization of sizes, thread types, materials and surface treatments (zinc plating, nickel plating, black oxide). With professional R&D team and advanced production equipment, we provide efficient sampling and mass production services, supporting bulk wholesale and long-term cooperative supply, delivering cost-effective, durable and tailored fastening solutions for industrial customers.
