Cold Heading Bolts - Precision Cold-Forged and Thread-Rolled for Superior Fastening Stability
These cold heading bolts are designed for fastening and joining applications across industrial, construction, and automotive sectors. Manufactured using a combined cold heading and thread rolling process, the cold heading densifies the material, significantly enhancing strength and toughness. This allows the bolts to withstand high pressure without thread stripping or breakage. Rolled threads are uniform and smooth, ensuring seamless, non-binding installation with a tight and secure engagement.
A variety of materials are available to meet specific requirements: carbon steel provides cost-effective strength for standard assembly tasks; stainless steel offers excellent corrosion resistance for outdoor or harsh environments; and alloy steels or brass provide unique properties for specialized applications. Surface finishes-including zinc plating, black epoxy coating, and electrostatic painting-further enhance corrosion and wear resistance, ensuring reliable performance in indoor, outdoor, humid, or dusty conditions. Specifications such as size, head type, and thread pitch can be customized according to technical drawings, and OEM/private labeling services are fully supported.
