Rivets come in various shapes, sizes and materials to accommodate different joining requirements. Some of the most common uses for rivets include:
Aerospace and Aviation
Rivets are integral components in the manufacture and repair of aircraft. They are used extensively to assemble the airplane fuselage, wings, engine cowlings and other structural parts. Aviation industry standards require rivets that can withstand substantial vibration, wind and G-forces. Aluminum and titanium are common rivet materials in aircraft construction due to their high strength-to-weight ratio. Countersunk rivets are often used to create a smooth external surface.
Cars, trucks and other automotive vehicles make wide use of rivets and specialty fasteners for assembly. Rivets provide robust, reliable connections for sheet metal parts like doors, hoods, trunk lids, roof panels and fenders. They are also used on the body framework and in the engine compartment. Stainless steel rivets have excellent corrosion resistance while aluminum rivets are lightweight. Self-piercing rivets allow direct joining of dissimilar metals.
Miniature rivets are integral components in many electronics like computers, mobile devices, home appliances, communications equipment and more. They provide reliable mechanical fastening while maintaining electrical connectivity for circuits. Electronics rivets are precisely engineered for properties like resistance, connectivity and avoidance of electromagnetic interference.
The extensive network of sheet metal ducting used in HVAC (heating, ventilation and air conditioning) systems is assembled predominantly with rivets. Their ease of installation and reliability in sheet metal connections make rivets well-suited for joining duct sections, adding hangers and straps, and installing other components. Stainless steel rivets withstand humidity and extreme temperature fluctuations.
Though not as common as welding, soldering or threading, riveted connections have applications in plumbing systems. Copper rivets can join copper pipes and tubes. Stainless steel rivets withstand high water pressures and resist corrosion from exposure to water. Plumbers may use rivets when other joint methods are impractical.
Building and Construction
Rivets have many applications in building and construction projects. Aluminum and stainless steel rivets create durable roofing systems. Rivets assemble steel stud wall framing. Decorative rivets can provide an artful, upscale look on furniture and architectural details. Large structural rivets connect steel beams and girders in bridges, cranes and high-rise buildings.

Boilermaking and Pressure Vessels
Boilermakers rely extensively on riveted joints to fabricate boiler components, pressure vessels, vats, storage tanks and similar products, especially those operating under high temperature and pressure conditions. Rivets distribute stresses efficiently. Lap joints with multiple staggered rows of rivets prevents seam leakage.
Ship hulls, decks, bulkheads and other marine components are commonly joined with rivets. The extensive vibrations, saltwater exposure and dynamic forces exerted on ships require extremely rugged, reliable fasteners. Lap joints with many rows of rivets form seam connections. Countersunk rivets provide an aerodynamic exterior surface.
Rivets have long been a trusted fastening method in the railroad industry for assembling locomotives, freight cars, tracks and related components. High shear strength resists the dynamic loads and impacts of railroad service. Large structural rivets connect critical load-bearing elements. Stainless steel resists corrosion from weather exposure.
Industrial machinery of all types - processing equipment, machine tools, engines, pumps, compressors, presses and more – use rivets for assembly. They form strong, rigid connections between metals parts that must withstand vibration and shock loads. Various rivet materials suit different machinery lubrication and environmental conditions.
Home and commercial appliances like refrigerators, washers, dryers, dishwashers, stoves and microwave ovens use rivets in their manufacture. The sheet metal casings as well as interior components and electronics get assembled mainly with specialty rivets suited for automated appliance production. Stainless steel and aluminum are common choices.
The manufacture of playground slides, swing sets, climbers and other structures often involves riveted joints to connect tubing, bars, platforms and fabricated parts. The repetitive nature of playground installations lends itself to automated riveting. Stainless steel provides corrosion resistance and aluminum brings light weight.
Rivets apply in numerous furniture applications from office chairs to beds and cabinets. They assemble stainless steel outdoor furniture. Decorative rivets adorn handcrafted furniture. Mechanical fasteners like threaded inserts in cabinets often get installed along with rivets. Durability and aesthetics motivate rivet choices.
The versatile rivet continues to be a popular, reliable fastening method valued across many industries. Advancements in materials, coatings and installation processes expand the capabilities of modern rivets. With an understanding of the technology and uses, design engineers can take full advantage of rivets. CNC Milling CNC Machining
