Rivets are one of the most versatile and widely used fasteners in manufacturing and construction. A rivet is a short cylindrical rod with a head on one end that is inserted through holes in multiple layers of material. The tail end is then deformed with a riveting hammer or rivet gun to create a second head and clamp the layers together.
Rivets have been used since ancient times to assemble armor, bridges, ships, and buildings. Today, rivets continue to be a preferred fastening method in many industries due to their strength, durability, and reliability. Understanding the different types of rivets and their various uses can help manufacturers and builders select the right rivet for their application.
Common Uses for Rivets
Aircraft and Aerospace Applications
Rivets are extensively used in aircraft and spacecraft construction to join the thin sheets of aluminum that form the outer skin or fuselage. Aerospace rivets are lightweight and strong to withstand vibration, pressure changes, and stress over repeated cycles. Different types such as blind, drive, flush, and countersunk rivets are used for assembling wings, engines, tail sections, and other flight control surfaces.
Metal Building and Bridge Construction
Structural rivets, usually steel, are relied upon in building construction, transmission towers, and bridges. They assemble I-beams, channels, and girders to frame high-rise buildings, factories, stadiums, and power infrastructure. Rivets connect steel plates on bridges to withstand tension and compressive forces from traffic and wind loads. Using rivets rather than welding simplifies on-site bridge assembly.
Shipbuilding
Marine grade rivets connect steel hull plates in shipbuilding. The hull experiences constant wave pressure and engine vibration which can loosen nuts and bolts. Rivets form permanent connections that resist shock and fatigue. Caulking seals the gaps between plating. Different structural sections are joined with flush rivets for smooth hulls with minimal drag.
Railroad Applications
Rivets hold together rail tracks, locomotives, and freight cars. Junctions between rails are joined with track bolts and e-clips on the underside. Rivets assemble transmission housings, couplings, wheels, and suspension components on locomotives and other rolling stock. Lightweight rivets are ideal for joining aluminum panels on high-speed trains.
Cranes and Construction Equipment
Large machinery such as cranes rely on heavy-duty rivets at joints subject to tension and shearing forces. Rivets provide a reliable, permanent method of assembling booms, jibs, bases, and drivetrain components that handle dynamic loads. Countersunk rivets allow for flush exterior surfaces.
Automotive Manufacturing
Self-piercing rivets (SPR) are widely used in automobile manufacturing to join sheet metal components and sub-assemblies. SPRs pierce through layers of metal while forming a mechanical bond. This eliminates the need for pre-drilled holes and separate fasteners like nuts and bolts. Automated SPR installation saves time and cost on the assembly line.
Appliances and Electronics
Small aluminum and steel rivets assemble the internal components and outer shells of appliances, computers, medical devices, and electronics. The vibration resistance and longevity of rivets prevents loosening over decades of use. Streamlined automated riveting systems allow high-volume production.
Common Types of Rivets
Solid Rivets
These feature a solid shank and are the most traditional type of rivet. Steel, aluminum, copper, and monel metal are common materials that provide shear and tensile strength. Used where heads need to be flush for streamlining and appearance.
Blind Rivets
Also known as pop rivets, these can be installed on one side when there is only access to a single surface. This allows riveting of hollow or closed structures. The mandrel stem is pulled to expand the rivet body.
Drive Rivets
They have a hollow stem that is hammered or pressed to splay outward and form the second head. Used where a hammer or rivet gun cannot access the tail end.
Flush Rivets
These have a countersunk head that sits flush with the surface for applications where protruding heads cannot be tolerated. The tapering allows optimization of aerodynamic properties.
Self-Piercing Rivets (SPR)
As noted above, these special rivets do not require pre-drilled holes. The semi-tubular rivet punches through stacked sheets of metal to create a tight fit upon installation. Common in auto manufacturing.
Rivet Nut
This is a nut with external threads that can be installed into a hole to receive a bolt. Often used to create threads in sheet metal too thin for tapping threads. Provides removable fastener capability.
Key Considerations for Choosing Rivets
- Shear and tensile strength needed for the application
- Materials being joined - metals, composites, plastics etc.
- Accessibility to both sides or single sided
- Flush heads required or not
- Permanent versus temporary fastening
- Compatibility with drilling, punching, or self-piercing installation
- Cost and ease of automation in high volume production
By understanding the strengths and limitations of the various rivet types, manufacturers can select the optimal fastening solution. Riveting remains a tried and true method for assembling components that need to withstand vibration, shock, and fatigue over long service lives. Continued innovation in rivet designs and installation processes will ensure rivets retain an essential role in fabrication and construction. CNC Milling
