A rivet consists of a smooth cylindrical shaft with a head on one end. The rivet is inserted into pre-drilled holes in the materials being joined, and the excess shaft is then upset, or mushroomed out, to form a second head. This creates a strong joint that holds the materials together.
Rivets come in a variety of styles, sizes and materials to fit different applications. Some of the most common uses for rivets include:
Aircraft Construction
One of the most prominent uses of rivets is in aircraft construction. Rivets are ideal for aviation applications because of their light weight, high strength, and ability to withstand vibration and extreme temperatures.
Nearly all aircraft, from small single engine planes to large commercial jets, contain thousands of rivets in their frame and skin. The fuselage, wings, Empennage and other components are assembled using rivets. Certain high-strength alloys, like aluminum and titanium, are commonly used for aircraft rivets.
Using rivets instead of welding or bolts allows for lightweight and streamlined designs. In addition, rivets distribute stress evenly and can be installed quickly during manufacturing. This was especially important during WWII when aircraft production ramped up significantly.
Today, specialty rivets continue to be developed for use in supersonic and advanced composite aircraft. Researchers are also working on “smart” rivets embedded with sensors to monitor airflow and structural integrity.
Bridges and Steel Buildings
Steel construction of all types, including bridges, towers, platforms, cranes, transmission towers, and frame buildings utilize rivets.
Structural steel rivets are usually heat-treated carbon steel and available with round, countersunk, or conical heads. They are a preferred fastener due to their vibration resistance and ability to withstand loading stress and fatigue.
Riveting provides a consistent, reliable connection method for joining gusset plates, I-beams, channels, and other steel elements. The Sidney Harbor Bridge in Australia, constructed in the 1930s, contains over six million rivets.
While welding has displaced some riveting for steel construction, rivets remain common for bridge assembly. They allow connecting stiffening gusset plates and joining sections of box girders or trusses. Using both welding and riveting provides the benefits of strength with added redundancy.
Ships and Boats
Shipbuilding has historically relied on rivets to assemble large hull structures. The riveted hulls of WWII naval ships displayed exceptional damage resistance during combat.
Marine grade rivets are highly corrosion resistant while maintaining good shear and tensile strength. Common materials include Monel, silicon bronze, and copper. They are essential for the proper construction of barges, cruise ships, tankers, submarines, and other vessels.
Riveting is also important for smaller aluminum boats and yachts. Many parts, including stringers, transoms, hull overlays, and decking, all utilize rivets for durability and waterproof connections. Marine rivets come with round or flat heads, or as drive screws, depending on accessibility.
Automotive Applications
Rivets play a key role in manufacturing cars, trucks, and motorcycles. The auto industry makes wide use of standard blind rivets which can be quickly installed by automated tools.
Some common uses include attaching:
- Door skins and hangers
- Fenders, bumpers, and spoilers
- Roof panels and drain troughs
- Trunk lids and hoods
- Truck beds and trailer panels
- Wheel liners and splash guards
Rivets provide a strong mechanical bond without welding, allowing components to be aligned precisely. Automotive grade rivets come in steel, aluminum, and specialty polymers to withstand road vibrations, weather, and corrosive conditions.
Appliances and Electronics
Many home and industrial appliances rely on specialty rivets during manufacturing. The speed and reliability of automated rivet installation is ideal for high-volume production.
Applications include:
- Joining external shells on washing machines, dryers, and dishwashers.
- Assembling inner cooking chambers in ovens and ranges.
- Attaching control panels and wrap around flanges on refrigerators.
- Mounting computer chassis, electrical junction boxes, and LCD screens.
Electronics rivets are designed to handle thermal expansion and conductivity issues. Plastics joining often uses nylon, acetal, or polypropylene rivets. Demand grows for high strength and corrosion resistant hardware in appliances.
Construction and Hardware
In addition to structural steel buildings, rivets have applications in general building construction. Roofing projects use them to attach flashing, gutters, and downspouts. Rivets also fasten heating and ventilation ductwork, electrical conduits, plumbing fixtures, and drain pipes.
Various rivet types can substitute for nuts, bolts, screws, and welds in many situations. Applications include securing:
- Hinges, latches, and drawer slides
- Shelving units and furniture
- Signage, railings, and ladders
- Scaffolding and temporary bracing
- Post bases, utility boxes, and trailers
The convenience of rivets allows for quick repairs, attachments, and modifications during a wide range of construction and maintenance projects.
Industrial Machinery
Industrial equipment and machinery relies on rivets due to their vibration resistance, joint integrity, and installation speed. Heavy machinery utilizes large structural rivets for joining massive frame components.
Some typical applications include:
- Assembling crane booms, stands, and slides
- Attaching guards, flanges, and shafts on presses
- Joining conveyor belts, rollers, and housings
- Mounting bearings, sprockets, gears, drums, and pulleys
- Fastening chutes, hoppers, bins, and silos
- Securing legs, arms, and masts on lift equipment
The operating conditions in factories and processing plants demand high clamp loads and reliable connections from rivets. Stainless steel and monel are common options for corrosion resistance.
Conclusion
From early boilers to modern electric cars, rivets have proven their versatility across countless engineering challenges. Their simplicity, strength, and ease of installation continues to make them a go-to mechanical fastener for all types of construction and manufacturing.
As technologies advance, specialty rivets are evolving as well. Lightweight aircraft rivets, smart sensing rivets, high-temp composites rivets, and extra-large structural rivets are just some of the emerging varieties.
After over 4000 years of reliability, the humble rivet remains an essential hardware component and continues finding new applications in our manufactured world. CNC Milling CNC Machining
