How Double Cap Rivets Work in Detail
- Components: A double cap rivet has two metal caps — one with a post (male) and a second cap (female) that fits over the post.
- Installation: First, a hole is punched through the materials. The post side is pushed through the hole(s), and then the female cap is placed on the protruding post.
- Setting: Using a rivet setter tool and a mallet (or an industrial press), the post is struck. The impact causes the post to flatten and expand inside the female cap, locking the two caps together and clamping the materials firmly.
- Result: The rivet holds the layers tightly, providing a durable and decorative fastening with a finished cap visible on both sides of the joined materials.
Applications
Double cap rivets are commonly used in leatherwork, canvas, and fabric projects such as bags, straps, and accessories. They provide a sturdy hold without sewing and add a neat, finished look on both sides of the joint.In summary, double cap rivets work by mechanically locking two metal caps together through a deformed post after being set with a hammer or press, securely fastening layers of material with a clean appearance on both sides.
