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

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

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

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

4. Countersunk rivet cores: For riveted components requiring a smooth and aesthetically pleasing surface after assembly.

5. All-Aluminum Pull-Through Rivets: The rivet bodies are made of aluminum wire, ensuring an aesthetically pleasing and durable finish that never rusts, suitable for softer connecting materials.

6. Large Brim Pull-Through Rivet: This rivet, compared to standard pull-through rivets, features a significantly larger aluminum cap diameter. When riveted to connecting parts, it offers a larger contact area, providing a stronger support surface to enhance torque strength and withstand higher radial tensile forces. Suitable for securing soft, fragile surface materials and oversized holes, it offers special protective applications for soft materials due to the increased brim diameter.

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