Aircraft and Aerospace Applications
Rivets are extensively used in the assembly of aircraft and spacecraft. They are the preferred fastener in aviation because of their high strength-to-weight ratio and reliability. Rivets used in aircraft are predominantly aluminum and titanium alloys that provide corrosion resistance while still being lightweight.
Some of the aircraft parts assembled with rivets include wings, fuselage skins, bulkheads, control surfaces, engine nacelles and landing gear. Rivets allow for efficient automated assembly and ensure robust structural integrity for flight safety. Different types of rivets are used such as blind, flush and drive rivets depending on accessibility and aerodynamic requirements.
Rivets are commonly used in automotive manufacturing to assemble body panels and frame components. Steel rivets provide durability and vibration resistance while aluminum rivets are preferred for lighter materials. Applications include attaching fenders, hoods, doors, roofs, bumpers and trim pieces to the vehicle frame. Rivets allow for quick installation, uniform clamping force and reliable performance on the road.
Self-piercing rivets (SPR) are gaining popularity in automotive manufacturing because they do not require pre-drilled holes. The rivet punctures the top layer of material and locks into the bottom layer for firm attachment. This saves time and costs in the assembly process. Rivets will continue being a trusted fastening method for automotive fabrication.
Joining Pipes and Tubing
Plumbers, HVAC technicians and mechanical contractors frequently use rivets to permanently join pipes, tubes and accessories. Common applications include connecting water lines, gas lines, heating and cooling ductwork, rain gutters and more. The rivets seal the joints and withstand vibration and pressure fluctuations within the piping system.
Stainless steel and copper rivets provide corrosion resistance when joining galvanized steel, copper or PVC pipes. Installers use hand rivet tools for small jobs and pneumatic riveters for large commercial projects. Riveted joints are reliable for liquid and gas transport in plumbing and mechanical systems.
Securing Rail Tracks
Rivets play an important role in assembling and maintaining railroad tracks. Steel riveted connections are used to attach the steel rails to railroad ties along the track. This secures the rails in proper alignment to handle trains passing over. The rivets allow for slight movement from railroad car weight and thermal expansion of the rails.
Riveted joints are also used when joining new sections of rail tracks. This provides seamless running surface for trains traveling over them. Onboard rail maintenance crews use air powered riveting tools to replace damaged or worn out rivets and keep the tracks in service. The vibration resistance and shear strength of rail rivets are important for railroad safety.
Heavy Equipment and Machinery Manufacture
Heavy machinery for construction, mining, agriculture, and other industrial sectors use plenty of rivets in their fabrication and assembly. The frame, arms, buckets, blades and component enclosures are commonly joined using steel rivets. They provide rigid and robust attachment points on equipment that sees harsh conditions.
Using rivets simplifies production by allowing assemblers and welders to quickly connect sections while still maintaining structural integrity. Riveted connections also tolerate high vibration levels caused by powerful diesel engines and percussion tools. Rivets will continue playing a critical fastening role in heavy machinery manufacture.
Building and Bridge Construction
Rivets were extensively used in the construction of skyscrapers, arenas, factories, bridges and other structures prior to the adoption of arc welding. There are still many ways rivets are used today in building and civil engineering projects. Connecting steel I-beams, girders, trusses and rebar frameworks is a common application. Utility buildings, farm structures, stadiums and temporary shelters often use aluminum and galvanized steel rivets.
Rivets provide reliable connections that allow some flex in the structure during high winds or earth movements. They are also easy to install in the field during construction. While welding has replaced rivets for permanent joints in most new buildings, they are still useful for temporary fixtures. Older riveted bridges continue performing well beyond their design life, which is a testament to the longevity of riveted connections.
Shipbuilding and Maritime Applications
Ship hulls, decks and marine equipment routinely use thousands of rivets during their initial fabrication. The extensive use of rivets in boat building allowed for mass production of ships and barges during wartime efforts in the 19th and 20th centuries. While welding has mostly replaced rivets in ship construction, they are still used when welding is unsuitable. Some advantages of using rivets include:
- Excellent corrosion resistance underwater
- Tolerates vibration and shock loads
- Ease of installation in confined spaces
- Ability to seal out water leakage
Common marine applications include attaching hull plating, joining ship frames, securing cable guards and railings, assembling crane pedestals, and anchoring deck gear. Using rivets and sealant provides watertight integrity in demanding ocean environments.
Lightweight aluminum rivets are commonly used when assembling electronic device covers, racks, and computer cases. The rivets provide good electromagnetic interference (EMI) shielding compared to screws. Rivets also allow for electrical grounding between case panels. Stainless steel or aluminum rivets are easy to install manually or with automation in electronics fabrication.
Pop rivets are popular for fast repairs and modifications by field technicians. They quickly fasten new brackets, racks and access panels inside equipment enclosures. Rivets will continue enabling compact, rugged enclosure designs for protecting delicate electronics.
Secure Military and Commercial Products
Rivets are often used to deter tampering and prevent access to sensitive components. Bank vaults, armored trucks, ATM machines, safes, prisoner transport vehicles and military equipment may all make use of rivets for security reasons. The permanent deformation of the rivet ends prevents removal of panels and doors. This protects cash, valuables or other critical contents from theft and unauthorized handling.
Access hatches, gun ports, storage covers and door locks on military vehicles are often riveted shut. Attempting to drill out the rivets is difficult and time consuming. Rivets help delay and deter battlefield pilfering. For maximum security, specialty rivets with breakaway heads are installed to self-destruct upon disassembly attempts.
Rivets have proven their usefulness for over a century in manufacturing and construction. Easy installation, high strength and durability make rivets a go-to mechanical fastener for assembling everything from delicate electronics to massive ships and bridges. New riveting tools and techniques continue improving the process while new alloys extend their performance. Rivets will no doubt maintain their key role in fabrication and industry for generations to come. Their versatility and reliability make rivets a staple component in manufacturing.
