Rivets are mechanical fasteners that are comprised of a smooth head at one end and a tail on the other. They are ideal for joining a variety of objects by inserting a headless end through two surfaces. These fasteners are then molded into a head shape using equipment like a hammer or rivet tools. During its installation, a rivet is placed in a pre-drilled hole, and the tail is deformed or bucked using rivet tools like a hammer or rivet gun. This expands twice its original diameter, holding the rivet firmly in place. They are suitable for mechanical applications like joining aluminium, steel, or copper plates to prevent the loosening of joints.
Materials for the Rivets:
They are available in a variety of materials, including:
- Nickel Copper Alloy Rivets
- Stainless Steel Rivets
- Copper Rivets
Types of rivets:
These fasteners come in the following types:
These rivets feature a shaft with a hole (hollow tube), usually at the end of the tail, which expands upon applying force. They come with different head styles like oval, flat, countersunk, or button.
They are efficient and easy to fit, even with finger pressure. They snap together easily, offering a fast and neat appearance. They come as male and female components.
They have mainly used rivets in areas where high safety and reliability are crucial. They are also known as original rivets, with a solid shaft resistant to vibration, temperature, and water.
Blind rivets, also referred to as drive rivets, are ideal for hard-to-reach areas. They are installed from one side only and feature a mandrel at the center that expands once inserted into pre-drilled holes.
Threaded insert and rivet nuts:
These are tubular, one-piece insert fasteners applied entirely from one side to integrate strong, seamless, and permanent threading into fragile material sheets.
Application of Rivets:
These mechanical fasteners offer remarkable flexibility and reliability for fastening metal, plastic, wood, and other objects. Ideally, they are suitable for the restriction of thin and delicate materials. The basic everyday applications of riveting include:
- Woodworking and decorative finishing
- Window blinds and coverings
- Building and Construction
- Aviation, aerospace, and automotive
- Transportation and Infrastructure
- Electric and magnetic motors
- Fine metalwork
- Pots and pans
