Rivets are a versatile fastening technology that have been used for centuries in manufacturing and construction. A rivet is a mechanical fastener that consists of two main parts - a cylindrical shaft and a head. The shaft is inserted into holes in the materials being fastened and the head is deformed on one end to clamp them together. Rivets come in a wide variety of materials, sizes and styles to meet different fastening needs. Here is an overview of the many uses for rivets in industry and building.
Aircraft and Aerospace Applications
Rivets play a critical role in aircraft construction. Aircraft grade rivets are made from lightweight and high strength materials like aluminum, titanium and specialty alloys. The fuselage, wings and other components of planes are assembled using thousands of rivets. Rivets offer high shear and tensile strength to withstand flight stresses while adding little weight. They also allow for precision fastening during aircraft assembly.
Space vehicles and satellites also rely extensively on rivets and specialty fasteners. Rivets used in aerospace applications require expertise in design, material selection and quality control. Aerospace rivets must maintain their strength and integrity across a wide range of temperatures and operating conditions.
Automotive Uses
Rivets are common in automotive manufacturing for joining interior and exterior components. Self-piercing rivets (SPRs) are often used to fasten metal sheets and other automotive body parts. SPRs pierce through stacked components and flare out to lock them together. This creates a strong solid rivet joint without the need for pre-drilled holes. SPRs enable faster and more automated assembly in auto plants.
Standard rivets are also used for attaching trim, mirrors, handles and other hardware to vehicle bodies. Rivet nuts allow components to be secured with bolts rather than welds. Plastic rivets provide fastening without corrosion for interior pieces. Automotive grade rivets meet specifications for strength, corrosion resistance and durability over vehicle lifetimes.
Industrial Equipment and Machinery
Rivets are ubiquitous in production machinery and equipment. Industrial rivets made from steel, stainless steel, aluminum and other alloys provide robust and reliable fastening. Countersunk rivets allow for flush surfaces important for movement and wear. Self-locking rivets feature a locking collar that prevents loosening from vibration. Large structural rivets connect heavy load-bearing components.
Using rivets rather than welding simplifies machinery assembly and maintenance. Rivets permit field repairs and part replacement without costly rework. Industries making extensive use of rivets range from plant equipment like compressors and boilers to agricultural machinery, robotics, vehicles, processing equipment, tools and more. Rugged rivets withstand harsh operating environments.
Building and Construction Applications
Rivets have many structural fastening applications in building construction. Aluminum and stainless steel rivets provide exterior facade systems with lightweight strength and corrosion resistance. Steel rivets anchor rebar in concrete foundations and structures. Copper and brass rivets offer aesthetically appealing fastening for architectural features.
Interior metal framing in walls, ceilings and HVAC systems is joined with rivets. Plastic rivets assemble wiring tracks, pipe hangers and ducting. Blind rivets allow fastening when only one side is accessible. Rivet nuts provide mounting points for electrical boxes and fixtures. Rivets also assemble trusses, railings, ladders and other building components where strength and durability are vital.
Marine and Underwater Uses
The marine environment poses corrosion challenges that make rivets ideal for boatbuilding and marine structures. Stainless steel and aluminum rivets withstand saltwater exposure. Iron and steel rivets may be zinc plated for added corrosion protection. Countersunk flat head rivets improve hydrodynamics on vessel exteriors. Marine grade rivets meet stringent specifications for quality control.
In underwater construction, rivets allow for reliable connections free of sealing issues. Hydraulic rivet tools can operate down to 300 feet underwater to facilitate offshore repair and construction. High strength structural rivets are commonly used in piers, oil platforms, pipelines and other marine infrastructure.
Specialty Rivet Types and Uses
In addition to standard solid and blind rivets, there are various specialty rivet types engineered for specific applications:
- Drive rivets have a ribbed hollow shaft that grips tightly when installed to eliminate spin-out. Used for high torque applications.
- Large head rivets distribute load over wider area for softer materials like plastics. Prevent pull-through failure.
- Shoulder rivets feature a precision ring to control driven depth for uniform clinching. Used in electronics and precision equipment.
- Grooved and ribbed shank rivets increase grip strength on slippery surfaces like plastics, glass and composites.
- Spiral rivets have coils that thread into pre-drilled holes for high tension applications like cabling, wiring and anchoring.
- Multi-grip rivets expand to fill different size holes and gaps in sheet metal stacks. Allow for dimensional variations.
- Plastic rivets snap or screw together without metal fastening hardware. Used for plastic parts and corrosion resistance.
Rivet Installation Methods
Rivets come in “blind” and “solid” styles to support different installation access and requirements:
- Blind rivets can be installed from one side when only single side access is available. Used extensively in aerospace, appliance and equipment applications.
- Solid rivets require access to both sides of the materials. Advantages include higher strength and inspection of completed rivets.
- Hand rivet tools like rivet squeezers and hammers provide simple but labor intensive installation. Automation has shifted most riveting to power tools.
- Pneumatic rivet guns use compressed air to quickly drive the rivet set and deform the rivet head. Common in construction, marine and industrial settings.
- Battery powered rivet tools allow portability and performance similar to air tools. Used for field work and remote applications.
- Hydraulic riveters generate several tons of pressure to install large structural rivets in civil construction and infrastructure projects.
- Robotic riveting systems provide automation for high volume manufacturing like aerospace and automotive assembly. Programmable for precision and consistency.
Rivets continue to find new applications as manufacturing technologies evolve. But the basic principle remains the same - rivets provide reliable mechanical fastening across industries where performance and safety are vital. Their versatility ensures rivets will remain a trusted assembly solution for many decades to come. CNC Milling
