Closed-core rivets, analyze various specifications and applications of rivets based on different requirements:

1. Open-ended stainless steel mandrel rivets: A high tensile strength and corrosion-resistant choice for your needs.

2. Enclosed Core Rivet: Designed specifically for covering the mandrel head after riveting, highly suitable for various applications requiring waterproofing.

3. Double-drum rivet: During riveting, the rivet mandrel pulls the end of the rivet body into a double-drum shape, clamping the two components to be riveted together, and reducing the pressure exerted on the surface of the components.

4. Countersunk Rivet Core Pins: For riveted parts requiring a smooth and aesthetically pleasing surface after assembly.

5. Full Aluminum Pull-Through Rivets: The rivet body is also made of aluminum wire, ensuring a beautiful and durable finish that never rusts. Ideal for connecting softer materials.

6. Large Hat-Flanged Socket Head Rivets: Compared to standard socket head rivets, these rivets have a significantly larger diameter aluminum cap. When riveted to mating parts, they offer a larger contact area, providing a stronger support surface to enhance torque strength and withstand higher radial tensile forces. Suitable for securing soft, fragile surfaces and oversized holes, these rivets offer special protective applications for soft materials due to the increased diameter of the hat flange.

7. Lantern-shaped Rivet: Single-sided riveting, the tail deforms into a lantern shape, with strong clamping force.
