Uses in Aircraft and Aerospace
One of the most safety-critical uses of rivets is in aircraft and aerospace applications. Rivets are extensively used in the assembly of airplane fuselages, wings, engine nacelles, control surfaces, landing gear, and many other structures. The aviation industry relies on the strength, reliability, and light weight of rivets to hold together critical components. Aluminum and titanium are the most commonly used rivet materials in aircraft because of their high strength-to-weight ratio.
Rivets are often preferred over welding in aircraft assembly because they allow for semi-permanent fastening. This means parts can be removed for inspection, repair, or replacement and then reassembled with the same rivets. Riveting also introduces less residual stress into parts compared to welding, which improves fatigue life. Proper installation of rivets is absolutely essential in aircraft application to prevent catastrophic failures in flight.
Uses in Bridges, Buildings, and Construction
Beyond aerospace, rivets are ubiquitous in steel construction for bridges, buildings, transmission towers, offshore platforms, and more. Steel rivets are used to connect structural steel members like beams, girders, and truss elements. They create strong joints that allow forces to be transferred between members.
Rivets used in construction are typically large in diameter (3/4" or larger) and made from carbon steel for strength. Installation involves heating the rivets with a forge to make them red hot before inserting and hammering into place. The rivet shank expands as it cools to form a tight connection. Rivets can join steel parts much thicker than typical aerospace applications.
Rivets are also very common in sheet metal building products like aluminum roofs, siding, rain gutters, and ventilation ducts. Smaller diameter aluminum and stainless steel rivets efficiently fasten thin gauge sheet metal while allowing for expansion and contraction from temperature changes.
Uses in Bridges and Heavy Equipment
Similar to buildings, rivets are used to assemble large steel structures like bridges, water towers, and heavy construction equipment. Bridge rivets may be up to 1-1/4” in diameter to bear immense loads from traffic and wind forces. On bulldozers, excavators, cranes, and mining trucks large steel rivets hold together critical load-bearing structural components. The protruding head of large rivets are often machined down flush for a smooth surface after installation.
Uses in Railroads
Riveting remains a popular joining method for railroads to assemble track components and railcars. Steel rivets are ideal for connecting rails to railroad ties because they accommodate longitudinal movement from thermal expansion and contraction better than bolts. Rivets are also extensively used in hopper cars, gondola cars, and other freight rolling stock to fasten side sheets and structural frames. Hardened steel rivets withstand the vibrations and inertia loads encountered during rail transport better than many other fastener types.
Uses in Pipelines
Underground gas and fluid pipelines are often assembled in the field using hot-driven rivets. The riveting crew heats carbon steel rivets to red-hot temperatures using propane forges and drives them into pre-drilled holes to connect pipe sections. This creates leak-proof joints even at high internal pressures. Pipeline rivets have very large diameters up to 2-3” for major oil and gas arteries. Riveted connections are reliable and withstand soil stresses better than threaded or welded pipes.
Uses in Plumbing, Food, and Medical Equipment
Aside from heavy steel construction, smaller rivets are ubiquitous in everyday metal products and equipment. Shiny aluminum and stainless steel rivets often assemble plumbing fixtures, kitchen appliances, medical devices, computer chassis, and machinery of all types. Popped rivets are commonly used to fasten thin aluminum sheet in heating and ventilation ductwork. Truss head rivets provide sleek visible connections in countertops, ladders, railings, racks, artwork, and retail displays. Rivets offer a simple and inexpensive but reliable fastening method for mass-produced goods.
Conclusion
From aircraft wings to bathroom faucets, rivets deliver reliable mechanical fastening across almost every industry. The versatility, strength, and ease of installation make rivets an essential joining method for critical infrastructure and common consumer products alike. As one of the oldest mechanical fasteners still in widespread use today, this humble but important piece of hardware will continue to hold the modern world together for decades to come.
