Precision Fastener Manufacturing: Kao Wan's Expertise in Hot Forged Nuts
As a professional nut manufacturer with decades of industrial experience, Kao Wan delivers robust fastening components engineered for demanding applications. Our specialization in hot forged nuts ensures superior structural integrity, making these products ideal for automotive, machinery, construction, and infrastructure projects requiring uncompromising reliability.
Technical Specifications & Material Excellence
Kao Wan's hot forged nuts are crafted from premium-grade carbon steel, alloy steel, and stainless steel, complying with international standards including DIN, ANSI, and JIS. Available in metric and imperial sizes (M4 to M36, 1/4" to 1.5"), these components undergo precision heat treatment to achieve hardness levels of 6H-12H. Surface treatments like zinc plating, hot-dip galvanizing, and phosphating enhance corrosion resistance for outdoor or high-moisture environments.
Certified Manufacturing Process
Our status as a certified nut manufacturer is reinforced by ISO 9001, CE, UL, and PSE certifications, validating strict quality control across raw material sourcing, hot forging, machining, and inspection. The hot forging process optimizes grain structure, eliminating internal voids to withstand extreme torque and vibration. Rigorous testing protocols include salt spray assessments, dimensional accuracy checks, and load-bearing simulations.
Industry Applications & Customization
Kao Wan's hot forged nuts serve critical roles in heavy machinery assembly, structural steel connections, wind turbine installations, and railway systems. Recent projects include supplying Grade 8 hot forged nuts for bridge construction in Southeast Asia and custom-designed flange nuts for hydraulic equipment manufacturers in Europe. OEM/ODM services support non-standard sizes, thread profiles, and branding requirements.
Sustainable Production & Global Reach
Operating advanced CNC machining centers and automated forging lines, we maintain rapid turnaround without sacrificing precision. As a responsible nut manufacturer, Kao Wan adheres to eco-friendly practices, including waste reduction systems and energy-efficient processes. With warehouses in Taiwan, Germany, and the United States, we ensure timely delivery to clients across 30+ countries.
