Rivets are one of the most versatile and widely-used fasteners in manufacturing and construction. A rivet is a mechanical fastener that consists of two main parts - a smooth cylindrical shaft and a head. The shaft is inserted into a pre-drilled hole and the head is upset, or deformed, to create a second head that sandwiches the materials being fastened together. The upsetting process mechanically joins the riveted materials together in a semi-permanent way.
Rivets have been used since ancient times to fasten metal parts together. Today, rivets continue to be ubiquitous and can be found in everything from aircraft and bridges to jeans, leather goods, and electronics. Some of the main advantages of rivets that make them so popular include:
Strength and Reliability
Rivets form a strong mechanical bond that holds well even under vibration and load. The upsetting process work-hardens the rivet, adding to its strength. Riveted joints distribute load widely which helps prevent fatigue and failure. Properly installed rivets rarely come loose or fail unless the riveted material itself fails.
Rivets come in a wide range of diameters, lengths, head shapes, and materials. This allows rivets to be used to fasten varying thicknesses of most metals, plastics, composites, wood, and other materials. Rivets can also join dissimilar materials. Custom rivets can be manufactured for unique applications.
The work-hardening that occurs during rivet installation creates a joint that maintains its strength over time. Rivets are resistant to shock, vibration, fatigue, corrosion, weather, and temperature extremes. This makes them suitable for critical structures and exposed installations.
Rivet installation is fast, simple, and cost-effective. It requires access to only one side of a joint for most applications. Little surface preparation is needed beyond drilling holes. Installation with hand tools or pneumatic presses has a low skill requirement. Riveted joints also don't require adhesives or finishing.
Some common uses for rivets include:
Aircraft and Aerospace Applications
Rivets are the preferred fastener in aircraft because of their vibration resistance, reliability, and light weight. Hundreds of thousands of rivets are used to assemble airframes, wings, skins, controls, engine nacelles, and interior components in both military and civilian aircraft. Rivets are also extensively used in missiles, rockets, satellites, space vehicles, and their components.
Metal Fabrication
Steel fabricators use rivets and special blind rivets to assemble truck bodies, rail cars, shipping containers, storage tanks, pressure vessels, cranes, transmission towers, platforms, staircases, ductwork, and countless other metal fabrications. Rivets allow pre-assembled modular components to be easily bolted together onsite.
Machinery Manufacturing
Manufacturers use rivets to assemble machinery frames, bases, covers, and other components. Large equipment like bulldozers, locomotives, print machinery, and power tools rely on rivets for durability in demanding conditions. Rivets are also ideal for small machinery like pumps, valves, appliances, engines, and tools.
Automotive Applications
Self-piercing rivets are extensively used in cars, trucks, buses, and motorcycles to join exterior panels like roofs, hoods, doors, and fenders to frames. Rivets create durable ratttle-free joints while allowing controlled crumple zones for safety. Interior components are also riveted together.
The marine environment demands rivets that can withstand corrosion. Ships, barges, and offshore platforms use thousands of rivets to assemble framing, hull plates, decks, bulkheads, railings, pipes, and other components. Rivets make ideal watertight connections.
Bridge Construction
Structural steel bridges are assembled with rivets and high-strength bolts. Rivets distribute loads efficiently while allowing for movement. Bridges use large diameter structural rivets to connect beams, bracing, decking, guardrails, and more. Riveting creates joints that last for decades.
Building Construction
Rivets secure steel beams, columns, trusses, railings, ladders, fire escapes, ductwork, elevator brackets, wall panels, roofing, siding, gutters, and flashing on all types of buildings. Rivets are also commonly used to assemble aluminum windows, doors, storefronts, curtain walls, and skylights.
Electronics Manufacturing
Miniaturized electronics packaging frequently relies on micro rivets, clinch nuts, and studs to assemble components and fasten circuit boards. Using rivets instead of adhesives or solder allows serviceability. Rivets also ground components and create durable attachments for ports and connectors.
Appliance Manufacturing
Manufacturers use rivets to assemble the cases, doors, handles, control panels, legs, shelving, frames, and other components of appliances and kitchen equipment. The vibrations and temperature cycles appliances endure make rivets ideal. Rivets don't loosen over time like screws or require adhesives.
Consumer Products
Durable goods like bicycles, wheelbarrows, carts, safety equipment, scales, racks, treadmills, and other products are manufactured using rivets. Rivets create solid connections between tubing, stamped brackets, pressed sheets, castings, and extruded parts while allowing knocked-down shipment.
In summary, rivets continue to be a preferred fastening method in countless manufacturing and construction applications. Their strength, reliability, economy, and ease of installation make rivets an essential industrial fastener with a bright future. Advancements in materials, coatings, installation processes, and analysis tools will enable rivets to improve the products we use every day. CNC Milling CNC Machining
