Semi-Tubular Rivets are an ingenious fastening solution for assemblies requiring a balance between secure joining and rotational freedom. Characterized by a solid head and a partially hollow shank, these rivets are widely used in the production of automotive linkages, luggage hardware, furniture, and electronic components. At Donghuang, we manufacture semi-tubular rivets that are prized for their low installation force requirements—making them ideal for delicate materials that might be damaged by traditional riveting. Whether you need a permanent joint or a pivot point, our semi-tubular rivets provide the precision required for reliable, long-lasting motion.
The performance of a semi-tubular rivet hinges on the precision of its tubular shank. Donghuang utilizes high-speed cold-heading equipment to ensure that the hollow portion is perfectly centered, allowing for a consistent, rolled clinch during installation. This uniformity is essential for manufacturers using automated machinery, as it prevents jamming and ensures that every clinch point is structurally identical. We offer these fasteners in brass, copper, and carbon steel, providing the specific conductivity, malleability, or strength needed for your product. Our technical team works with you to determine the ideal shank length and diameter, ensuring the rivet sets cleanly without the risk of splitting or barrel deformation.
Semi-tubular rivets are uniquely capable of functioning as a pivot point for moving assemblies, such as folding chairs or scissors. Because the "set" force is applied exclusively to the hollow tip, the body of the rivet remains rigid, allowing the joined components to rotate around the shank. To support these applications, Donghuang provides a wide variety of head styles, including flat, oval, and truss heads, which are finished to prevent abrasion against the moving parts. Our rivets are also available in a variety of decorative finishes, such as nickel or chrome, ensuring that the hardware is as visually appealing as it is functional.
At Donghuang, we believe in supporting the cost-efficiency of our clients. Our semi-tubular rivets are built for consistent performance in high-speed riveting equipment, significantly lowering the total cost of ownership for your assembly line. Every batch undergoes rigorous dimensional checking and clinch-force testing to ensure they meet your specific engineering requirements. By choosing Donghuang, you are selecting a partner that understands the nuances of pivot-fastening technology, providing the reliable, high-quality components necessary to keep your production lines moving and your products performing flawlessly for the end-user.
