Cap Nut

Products, also known as acorn nuts, are fasteners that combine protection with decorative appeal. Their design features a standard hex body topped with a domed or rounded cap. The primary benefit of products is full coverage of the bolt end, which enhances appearance while preventing damage from impacts. Manufactured to ISO 1212 standards, the cap completely encloses the exposed threads of a bolt, effectively shielding them from rust, dirt, and debris. The smooth, rounded shape also eliminates sharp edges, improving safety and giving the product a refined feel. The hex base allows for standard wrench tightening, and the internal 6H-grade thread ensures precise engagement. Products are the perfect finishing touch for applications with exposed fasteners.

Cap nuts are widely used in furniture manufacturing, architectural decoration, medical equipment, fitness devices, and outdoor recreational products-any application where fasteners are visible. In furniture, they provide a clean, finished appearance on exposed bolts for tables, chairs, and cabinets. For architectural applications such as railings and handrails, they offer both protection and a polished look. In medical or rehabilitation equipment, they eliminate hazardous protrusions to prevent accidental injury. On outdoor products like patio furniture and playground sets, they protect fasteners from weathering and corrosion. Products seamlessly combine practicality with an enhanced aesthetic.

These nuts are made from quality carbon steel 1020A, stainless steel 304, or lightweight aluminum alloy. Carbon steel versions are typically finished with zinc plating (ASTM B633) or nickel plating (ASTM B733), providing 72-hour salt spray resistance. Stainless steel 304 offers excellent corrosion resistance for outdoor environments. Aluminum alloy provides a lightweight solution with a natural or colored finish. All cap nuts are ISO 9001 certified, with the cap securely attached and dimensional tolerance controlled within ±0.05 mm. Customization is available for different cap shapes (round, square), special surface treatments (paint, electrophoretic coating), and colored aluminum options. Supplied in packs of 200–500 pieces per specification with clear labeling, products facilitate easy selection and use to enhance your product's design.
