Rivets are a ubiquitous little fastener used in many industries and applications. Though small, the rivet plays an important role in holding together structures and components. Let's explore the many uses of this modest but mighty fastener.
In Manufacturing and Construction
Rivets are commonly used in manufacturing and construction for assembling metal parts and structures.
Metal Fabrication - Rivets are ideal for joining sheet metal in products like appliances, electronics enclosures, office furniture, racks, and shelving. The riveting process deforms the rivet shank, creating a permanent mechanical bond between metal parts. Rivets allow for quick and secure fastening without welding or hardware.
Building Construction - Rivets secure steel beams, girders, railings, and other structural components in bridges, towers, and buildings. The strong clinching grip and vibration resistance makes rivets the go-to fastener in construction projects. Their high shear strength bears heavy loads over time.
Shipbuilding - The marine industry depends on rivets to assemble hulls, masts, and other parts in ships, boats, and barges. The saltwater environment demands durable, corrosion-resistant fasteners like stainless steel rivets. Riveting provides reliable watertight joins for vessel integrity.
Aircraft Assembly - Rivets are universally used in aircraft manufacturing to fuse fuselage skins, wings, engine housings, and other components. Hundreds of thousands of rivets may be used on a single plane. The aerospace industry chooses rivets for their lightweight strength and fatigue resistance through pressurization cycles.
In Infrastructure and Transportation
Rivets provide critical fastening strength in infrastructure from skyscrapers to rail lines.
Bridges - Structural steel rivets reinforce trusses, braces, girders, and frames in suspension, arch, cantilever, and other bridge types. Riveting is preferred for the durability to endure weathering and vibration from traffic loads. Stainless steel rivets resist corrosion from water and deicing chemicals.
Dams - Hydraulic structures utilize rivets for spillway gates, intake towers, and pipe braces. The high-clamp force and vibration resistance makes rivets suitable for the immense hydrostatic forces imposed on dam components.
Cranes - Rivets assemble the strong structural frames, booms, cab platforms, and bases of tower, bridge, and mobile cranes. Rivets distribute dynamic lifting stresses uniformly across connection points.
Railways - Railroad ties are spiked to rails with large diameter rivets. Rivets also fasten rails to bridge decks and tunnel liners. The extreme shear strength resists longitudinal movement under thermal expansion and heavy axle loading.
In Aerospace and Defense
Rivets are the choice fastener for aerospace and military applications where reliability is critical.
Aircraft - As noted above, rivets hold together nearly all components of planes from the control surfaces to the lavatories. Riveting maintains airworthiness through years of pressurization, turbulence, and landing impacts.
Spacecraft - Rivets assembled the Mercury, Gemini, Apollo, and Space Shuttle vessels. The space environment demands rivets that won't loosen from vibration during launch. Stainless steel and titanium rivets meet these needs.
Missiles and Weapons - The intense g-forces and temperatures endured during launch and flight require rivets on missile casings, rocket exhaust cones, and weapons systems. Specialty rivets withstand cryogenic or heated conditions.
Submarines - The enclosed, pressurized vessel of a submarine uses thousands of rivets. The joining strength and corrosion resistance contributes to sea readiness and crew safety. Custom high-strength rivets suit the deep dive demands.
Armored Vehicles - Rivets fasten vehicle hulls, turrets, and other armor plating together on tanks, personnel carriers, and other protected vehicles. Rivets distribute explosive loads from incoming projectiles across the structure.
In Consumer Goods
Though behind the scenes, rivets play a key role in mass-produced consumer products we use every day.
Electronics - Tiny rivets assemble smartphones, computers, TVs, and other electronic devices. Their miniature size suits precision joining of circuit boards, internal frames, and outer covers. Stainless steel resists corrosion from indoor humidity and chemical vapors.
Appliances - Internal frames and housings in refrigerators, washers, dryers, ovens, and other appliances rely on rivets for optimal alignment. Their vibration and shock resistance keeps components in place during shipping and use.
Furniture - Rivets construct the inner frames and bases supporting seating, beds, tables, shelves, and storage units in both home and office furniture. Riveting allows rapid production with strong, consistent joints.
Sporting Goods - Baseball bats, golf clubs, tennis rackets, football helmets, hockey sticks and more depend on small rivets. They rivet lightweight but sturdy materials like aluminum and composite polymers for equipment strength and playability.
Cars and Trucks - Auto bodies, engines, exhaust systems, and frames all use plenty of rivets for optimal handling capability. Rivets join high-strength steels and composites that protect passengers while reducing vehicle weight.
In Conclusion
The simple yet versatile rivet fastener has clearly left its mark on the constructed world. From skyscrapers to smartphones, bridges to battleships, and appliances to airplanes, rivets touch practically every manmade structure in some way. Their unique head and shank design creates solid clinched joints in all types of materials and applications.
