Rivets are a fastening technology that has been in use for thousands of years. A rivet is a mechanical fastener that connects two or more objects by inserting a metal pin through holes in the parts to be joined and deforming the free end so it does not pull back through the hole. The deformation in the end of the rivet is called the shophead or buck-tail.
Rivets come in a variety of styles, sizes and materials for different applications. They offer many advantages over other types of fasteners like screws or bolts. Rivets form a permanent connection that does not come loose over time or due to vibration. Installation is quick and only requires access from one side of a joint. Rivets distribute load over a wider area compared to screws or bolts. They can also seal against leakage better than threaded fasteners.
Common Uses for Rivets
Aircraft and Aerospace Applications
Rivets are extensively used in the manufacture and repair of aircraft due to their vibration resistance, reliability, and light weight. The aircraft industry was one of the first major users of rivets. Rivets help assemble the fuselage, wings, and other components that must handle enormous stresses over years of service. Aircraft rivets are made from lightweight materials like aluminum alloys, titanium, or specialty nickel or cobalt superalloys. Rivets come with flush or protruding shopheads.
Metal Fabrication
Rivets are ubiquitous in metal fabrication across many industries. They assemble sheet metal enclosures and frames for electronics, HVAC equipment, appliances, furniture, storage containers, and more. Steel, stainless steel, or aluminum rivets are common. Riveted joints have some flexibility that allows metal fabrications to handle movement, shock, and vibration without coming apart or cracking welds. Good shear and tensile strength resistance is also important.
Automotive Applications
Cars, trucks, buses, and their components are held together by millions of rivets. They attach body panels, frames, doors, hoods, trim, seats, and more. Rivets provide reliable attachments that withstand road vibrations and impact. Stainless steel, aluminum, and specialty polymer rivets are popular types. Using rivets instead of welding, bolting, or adhesive bonding speeds up assembly line production. Rivets allow some flexing between components. Automotive rivets have advanced corrosion resistance as well.
Plumbing, HVAC and Appliances
Behind the walls and under the hood of household fixtures and appliances lay hidden rivets. They assemble washing machines, dryers, dishwashers, refrigerators, air conditioners, furnaces, pipes, vents, ductwork, and associated sheet metal housings. The vibration resistance and sealing properties of rivets keep these products working reliably for decades. Stainless steel and aluminum rivets resist corrosion from condensation and leaks.
Electronics Assembly
Inside computers, appliances, machinery, medical devices, and telecommunications equipment you often find rivets. They quickly and reliably assemble sheet metal electronics enclosures, frames, and heat sinks without adding significant weight. The rivets provide good electrical conductivity between components and resistance to shock, vibration, and flexing. Electronics rivets come in aluminum, steel, copper, brass, and specialty alloys.
Construction and Architecture
While less common than welding or bolting, rivets do play a role in buildings and structures. Rivets allow some flexing between sheet metal roofing panels and wall/siding panels to handle expansion, contraction, and shifting better than stiff welds and bolts. Structural applications include bridges, towers, cranes, platforms, staircases, and more. Rivets also assemble trusses, building frames, and removable components. Stainless steel and aluminum rivets resist weathering.
Marine and Underwater Use
Shipbuilding, boat building, offshore oil platforms, docks, buoys, and other marine applications use rivets. The saltwater environment demands corrosion resistant materials like stainless steel, aluminum, copper, or nickel alloys. Rivets withstand the constant pounding of waves and hold up under loads from masts, winches, and rigging. Their vibration damping abilities and flexibility under shock loads make rivets ideal for vessels and equipment that is continuously moving.
Consumer Products
Pocket knives, watches, hand tools, backpacks, suitcases, bicycles, sporting goods, musical instruments, and more utilize rivets in their assembly. Small stainless steel or aluminum rivets are common. Rivets allow some flexing between material layers or components on products that undergo daily use and abuse. They install quickly on production and assembly lines. The permanent nature of rivets prevents consumer products from falling apart over time.
Key Benefits of Using Rivets
There are many advantages that make rivets a popular fastening choice across countless industries and applications.
- Quick and easy installation with no threading or torque requirements
- Join dissimilar or thin materials not suitable for welding or screwing
- Allow some flexibility and movement between assembled parts
- Vibration and shock resistant
- Reliable permanent fastening that does not loosen over time
- Only require access from one side of a joint
- Lightweight compared to most bolts
- Fast production line assembly times
- Repairs often possible by drilling out and replacing rivets
- Improved sealing against gas or liquid leakage in some cases
- Distribute loads over wider area than screws or bolts
- Resist corrosion better than screws in many applications
- Conduct electricity well between assembled parts
Rivets have proven themselves as a versatile, reliable, and easy-to-use fastening method across countless industrial and consumer applications. Improved rivet materials and installation tools continue to advance their benefits and use cases. While not suitable for every joining need, rivets solve many common problems with other types of mechanical fasteners. Their unique combination of strength, vibration resistance, corrosion resistance, sealing ability, and quick installation make rivets an essential component of modern manufacturing and product design. As long as the world needs strong, reliable, and lightweight mechanical attachments, rivets will remain a go-to fastening solution. CNC Milling CNC Machining
