Closed-core rivets, analyze various specifications and applications of rivets according to different requirements:

1. Open-ended stainless steel mandrel rivet: A high-tension and corrosion-resistant option for your needs.

2. Enclosed-core rivet: Designed specifically to encapsulate the mandrel head after riveting, highly suitable for various applications requiring waterproofing.

3. Double-drum Pull-Through 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: For riveted components that require a smooth and aesthetically pleasing surface after assembly.

5. Full Aluminum Pull-Through Rivets: These rivets feature an aluminum wire body, offering a beautiful and durable finish that never corrodes. Ideal for connecting softer materials.

6. Large Hat Rim Core Rivet: This rivet has a significantly larger aluminum cap diameter compared to standard core rivets. When riveted to connecting parts, it offers a larger contact area, resulting in a stronger supporting surface that enhances torque strength and can withstand higher radial tensile forces. Suitable for securing soft, fragile surface materials and oversized holes, it provides special protective applications for soft materials due to the increased hat rim diameter.

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