Aircraft and Aerospace
Rivets are extensively used in aircraft and aerospace applications to assemble the outer skin and structural components. Aircraft grade rivets are made from lightweight and corrosion resistant materials like aluminum, steel and titanium alloys. Rivets hold together sheets of metal that form the aircraft fuselage, wings and other parts. Using rivets instead of welding or bolts reduces aircraft weight. Rivets also allow for thermal expansion and contraction of the airframe due to temperature changes during flight.
The rivets used on aircraft must meet strict aviation industry standards for shear and tensile strength. Different types such as solid shank, blind, drive, flush and countersunk rivets are used. Selection depends on the materials being joined, accessibility and head profile. Proper installation and inspection is critical because structural failure of rivets can lead to disastrous consequences.
Bridges and Steel Construction
Rivets are used extensively in steel bridges, towers, cranes and framework buildings. They are the preferred fastener because steel construction often requires joining thick materials that bolts cannot accommodate. Structural steel rivets are made from corrosion resistant alloys and come with large diameter shanks.
Heat-driven rivets that use explosive charges to deform the tail are common. They install quickly and create a tight fit. Pneumatic impact rivet guns are also used. Riveting produces a durable connection that can handle dynamic loads and vibration in steel structures. It also allows for some flexibility to prevent cracking under seismic and wind stresses. Rivets distribute stress evenly, avoiding concentration that could lead to failure.
Railroads and Heavy Equipment
Rivets have long been used in railroads for assembling track components and rolling stock. Traditional railroad rivets were hammered in manually, but modern pneumatic riveters make the process easier. Rivets withstand the vibrations and mechanical stresses encountered in railroads well. They are also used for joining parts of heavy equipment like cranes, bulldozers and mining machinery. Large mechanical rivets are capable of handling high shear loads found in such applications.
Ships and marine applications employ rivets due to their strength and corrosion resistance. The hull, decks and superstructure of ships are assembled using thousands of rivets. They withstand the corrosive effects of seawater better than many alternatives. The watertight integrity provided by riveted joins is important for buoyancy. Riveting also dampens noise and vibration on ships which require stealth. Different grades of rivets are used for the hull versus decking based on strength needs.
Rivets retain popularity in automotive manufacturing applications, often when spot welding cannot be used. Weight considerations require automotive rivets made from lightweight materials like aluminum. Self-piercing rivets are commonly used for joining stamped sheet metal components of car bodies and frames. Access limitations often preclude welding, so rivets provide a fast alternative. Plastic and composite materials are also joined using specialty rivets in cars.
Appliances and Electronics
Many home and commercial appliances rely on rivets for assembly. While hidden from view, rivets join the outer shells of stoves, refrigerators, dishwasher tubs and washing machines. Small electronics like computers and cellphones also use tiny rivets internally. They are useful for assembling printed circuit boards, drives and components within electronic devices. Specialized micro-rivets are ideal for electronics that require precision fastening.
Construction and Hardware
A variety of rivets are used in building and hardware applications. Structural rivets assemble prefabricated steel beams and supports. Drive rivets attach metal roofing, siding, gutters and flashing. Dome head and countersunk rivets are used for trim and fixtures. Pop rivets allow easy riveting with only hand tools, useful in construction and repairs. Self-piercing and screw rivets fasten thick materials like concrete blocks, wood and plywood.
Crafting and Hobby
For crafters, artists, jewelers and hobbyists, rivets provide versatile and decorative fastening. Small aluminum and steel rivets affix materials like leather, plastic, wood, rubber and fabric. Copper rivets make durable and rustproof connections for outdoor projects. Large flared head rivets add ornamental flair. Colored and textured specialty rivets are available for creative uses. Riveted crafts, jewelry, accessories, models, decor, tools, sculptures and mixed media pieces can be fashioned.
The many varieties, sizes and materials of rivets accommodate countless securing needs across industries. While largely hidden, rivets deliver reliable fastening strength to critical structures and machines. Understanding the uses for rivets helps select the optimal type for an application. With a long history but continuing evolution, the rivet retains essential fastener status in manufacturing. This versatile staple will undoubtedly persist joining and assembling things big and small long into the future. CNC Milling
