Aircraft and Aerospace Applications
The aerospace industry was one of the first to adopt rivets for assembling aircraft frames and components. Rivets provide a strong, reliable mechanical attachment that can withstand the high stresses and vibration experienced during flight. Aircraft grade rivets are made from corrosion resistant alloys like aluminum and titanium. The riveted construction allows for inspection and repairs over the lifetime of the aircraft. Rivets are used to assemble the fuselage, wings, tail and flight control surfaces on both civilian and military aircraft. Critical structural joints are often double or triple riveted for redundancy.
Bridge and Infrastructure Construction
Rivets have long been a staple fastener for steel bridge construction. The first iron bridges in the early Industrial Revolution were assembled using hot rivets. Riveted construction continued to be the standard as bridge spans got longer through the 19th and early 20th centuries. Even as welding grew in popularity, rivets were still used extensively. The riveted connections provided flexibility to handle the expansion and contraction from temperature fluctuations. Riveting also didn’t require highly skilled labor. Today, high strength structural rivets are used in the construction of suspension bridges, steel arch bridges, truss bridges, towers, offshore platforms and other civil infrastructure.
Ship hulls have been assembled with rivets for over 2000 years. Lap joints riveted together continue to be the standard technique for barge and ship fabrication. The extensive use of rivets makes ships repairable and allows for periodic overhauls and inspections. Riveting also dampens noise and vibration for quieter operation compared to welding. High strength rivets join the steel plates that form the hulls of military and commercial vessels. Ship rivets must withstand corrosion from exposure to seawater. Riveting remains a vital process in shipyards and marine fabrication shops today.
Rivets play an important role in the assembly of cars and trucks. Self-piercing rivets are widely used in automotive manufacturing because they can join different types of materials like steel and aluminum. The riveting process is also fast, flexible and can be highly automated. This allows different body components like doors, hoods and panels to be accurately and quickly joined by robots on the assembly line. Structural joints in chassis, frames and heavy trucks that undergo high stress are also riveted. Rivets will likely continue being the preferred fastener for auto manufacturing.
Appliances and Electronics
Many home and commercial appliances rely on rivets for assembly. Using rivets to fasten sheet metal housings and frames is often more cost effective compared to other techniques. Riveting also allows appliances to be serviced and disassembled for repair as needed. Microwave ovens, washing machines, kitchen appliances, power tools and more all use rivets in their construction. Electronics equipment like computers, printers and rack cabinets also use rivets to assemble the metal enclosures while allowing access to internal components. Rivets withstand vibration while providing good electromagnetic shielding.
Railroad and Heavy Equipment Construction
Riveting is the method of choice for assembling railroad rolling stock, rail infrastructure and heavy machinery. Rivets provide the strength to handle dynamic loads and vibration during transport while allowing for disassembly when needed. Passenger and freight locomotives are constructed using thousands of rivets. Tank cars, hopper cars, flatcars and other railcars are also heavily riveted. Railroad ties are affixed to the rail bed using large spike rivets. Mining and earthmoving equipment like bulldozers, excavators and haul trucks all rely on rivets for cab, frame and component assembly. The ruggedness and reliability of riveting makes it ideal for heavy equipment construction.
Building and Furniture Manufacturing
The manufacturing of building components and furniture often involves using rivets to join parts. These include metal framed doors, windows, cabinets, shelving and more. The speed and efficiency of rivet installation allows high production rates. Using pneumatic and specialty rivet tools allows for quick fastening. Self-piercing rivets are also common since they do not require pre-drilled holes. Rivets allow the finished products to be disassembled later for repair if needed. This repairability makes rivets preferable for furniture compared to welding or glue. Riveting is likely to remain important for building and furniture component manufacturing.
Beyond major industries, rivets serve as reliable fasteners in countless everyday applications. Eyeglass frames, hand tools, bicycles, motorcycles, playground equipment, shelving units and more all use rivets during assembly. Rivets provide a balance of strength, economy and ease of installation not matched by other methods. Riveting also allows products to be periodically inspected, serviced and repaired over their lifetime. The versatility and simplicity of rivets means they will continue to be used for assembling all types of products well into the future.
In summary, rivets are one of the most ubiquitous industrial fasteners used today. The list of applications that rely on rivets is nearly endless. Manufacturing sectors ranging from aerospace to appliances to automotive all employ rivets during component and product assembly. Rivets meet the challenging criteria of providing reliable structural joints that perform consistently over time despite vibration, fatigue and corrosion. Engineers continue finding new applications for rivet fastening technology as manufacturing processes evolve. With their track record of versatility, strength and reliability, expect rivets to remain a staple across industries for generations to come. CNC Milling CNC Machining
