Rivets come in many sizes, materials, and head styles to accommodate different application requirements. Common materials for rivets include aluminum, steel, copper, stainless steel, and Monel. The most popular head shapes are round, countersunk, and brazier (also called universal) head rivets. Let's take a closer look at some of the top uses for rivets.
Aircraft and Aerospace Applications
The aerospace industry was an early pioneer in the use of rivets for aircraft construction. Rivets provide a strong, reliable fastening method to join the thin sheets of aluminum that make up the fuselage, wings, and other components. Hundreds of thousands of rivets are used in a typical aircraft. The rivets must withstand considerable vibration, fluctuating pressures and temperatures, and other stresses during flight.
Aircraft-grade rivets are made from high strength aluminum alloys, titanium, or specialty alloys like Monel. Monel rivets provide excellent corrosion resistance. Countersunk head rivets are extensively used to provide a smooth aerodynamic surface. Sophisticated automated riveting systems quickly insert thousands of rivets during aircraft assembly.
Metal Fabrication and Machinery
Rivets are commonly used in fabricated metal products to join parts made from sheet metal, extruded frames, plates, and other stock material. They provide a fast, simple way to mechanically fasten components without requiring welding or threaded hardware.
Common applications include HVAC ducting, electronic enclosures, motor housings, gear boxes, cranes, platforms, stairways/ladders, and transmission towers. Steel rivets are suitable for most industrial equipment when strength and cost are the main priorities. Stainless steel or Monel rivets add corrosion resistance for demanding environments.
Cars, trucks, and other vehicles use thousands of rivets in their construction. Body panels, frames, engine parts, drive train components, interior trim pieces and more are joined with rivets. Steel and aluminum rivets are the most common. Self-piercing rivets allow thinner high-strength steel to be riveted without pre-drilling. This improves efficiency in automated assembly plants. Structural rivets with large domed heads provide extra strength for critical joints.
Blind rivets can reach tight spaces between panels where conventional rivets won't fit. Exhaust hangers, brake components, and many other parts are attached with rivets due to their vibration resistance. Rivets also withstand road salts and weather without deteriorating like adhesives.
Building and Construction
Rivets have been used in building construction for over a century. They were a popular fastener to assemble structural steel buildings, bridges, and large infrastructure projects in the early 1900s. Rivets have since been mostly replaced with high-strength structural bolts. However, they are still widely used in construction for light-duty connections.
Common applications include:
- Connecting rebar in concrete foundations and structures
- Assembling metal roof trusses
- Joining aluminum soffits, siding, gutters, and flashing
- Installing heating and ventilation ductwork
- Attaching metal studs for interior framing
- Building outdoor decks, platforms, railings and ramps
- Securing signs, ornamental metal, and lighting fixtures
Rivets make a convenient alternative to welding or drilling and tapping holes for screw threads in many situations. The riveting process is also faster than fastening with nuts and bolts. Aluminum and stainless steel rivets resist corrosion in outdoor environments.
Shipbuilding and Marine Applications
The demand for strong, corrosion-resistant fasteners in marine applications led to the development of specialty rivets. Copper and bronze rivets were used historically to assemble wooden boats. Today, most fastenings have transitioned to stainless steel or Monel rivets. Marine rivets securely fasten fiberglass, wood, or metal components while resisting saltwater exposure.
Typical marine uses include:
- Hull assembly
- Attaching outboard motors
- Securing deck hardware
- Assembling railings and ladders
- Joining interior cabinetry and fittings
- Installing piping and plumbing
Blind rivets are easy to install in tight spaces below deck. Large diameter structural rivets provide necessary strength for hull joints. Proper selection of marine-grade rivets prevents fastener corrosion and failure.
Electronics and Appliances
Rivets offer a quick and economical fastening method for manufacturing consumer goods and electronic devices. Self-clinching rivets install permanently into sheets of aluminum, steel, or stainless steel with only access to one side required. This aids automated assembly of products like computers, smartphones, home appliances, and electronics. Other electronics uses include:
- Riveting internal frame/chassis components
- Attaching brackets, braces, and heat sinks
- Joining enclosure panels
- Securing wires, cables, and conduit
- Mounting circuit boards and LCD/LED displays
Plastics can also be riveted, but often require specialty polymer rivets or heat staking for effective fastening. The rapid, simple process of rivet installation makes it ideal for large volume manufacturing.
Additional Uses of Rivets
Beyond these major applications, rivets have many other uses including:
- Joining layers and handles of pots and pans
- Assembling grills, outdoor furniture, and lawn equipment
- Permanently attaching nameplates, serial tags, and identification plates
- Anchoring bolts, studs, and pins for more strength
- Securing cargo restraints and tie-downs in trucks and trailers
- Joining components on musical instruments like guitars
- Attaching aftermarket auto accessories like spoilers
- Recreational uses on ATVs, trailers, snowmobiles, etc.
The versatility, effectiveness, and economy of rivets ensure they will continue to be a popular mechanical fastener for assembly across many industries. Proper selection of rivet materials and using reliable installation practices allows manufacturers and builders to take full advantage of rivets. CNC Milling CNC Machining
