Rivets are one of the most versatile and widely used fasteners in manufacturing and construction. A rivet is a mechanical fastener that connects two or more objects by passing the shank through a hole in each object and mechanically deforming the shank end to create a head. The deformation of the shank tightly clamps the materials together. Rivets come in a variety of head shapes, materials, and installation methods to accommodate many different applications. Some of the most common uses for rivets are outlined below.
Aircraft and Aerospace Applications
Rivets are ubiquitous in aircraft construction because of their light weight, high strength, and ability to withstand vibration and extreme temperatures. Aircraft-grade rivets are made from lightweight and strong materials like aluminum, titanium, and specialty alloys. The most common rivet used is the solid shank rivet, where the rivet shank and head are machined from a single piece of material. Other types like blind rivets and specialty lock rivets are also used. Aircraft engineers select the optimal rivet style, head shape, material, and installation method for each application. Some key uses of rivets in aircraft include:
- Permanently joining skin sheets, ribs, bulkheads, and other structural components. Rivets are arranged in rows and patterns optimized for load distribution.
- Attaching hinges, engine pylons, and other hardware mounts to the airframe where high shear strength is needed.
- Providing an airtight seal along with fastening for compartments that need to be pressurized or watertight. The rivet head and shank create a tight seal when properly installed.
- Allowing for field repairs and modifications by drilling out old rivets and replacing them with new ones. This facilitates maintenance, upgrades, and battle damage repairs.
Rivets are often used along with adhesives and specialized fasteners like Hi-Loks for critical structures. The many advantages like high strength-to-weight ratio, flexibility, and proven performance make rivets ideal for almost every aircraft application.
Automotive Manufacturing
Rivets are extensively used in cars, trucks, buses, and other automotive products to assemble external body panels and interior components. The most common types are blind rivets, solid rivets, and self-piercing rivets. Applications include:
- Joining outer body panels like doors, hoods, deck lids, fenders etc. Self-piercing rivets installed by automated assembly machines clinch panels together by piercing the top layer and flaring on the backside.
- Attaching interior trim pieces, panels, rails, and other hardware to the body structure. Blind rivets allow installation access from only one side.
- Joining overlapping sections of unibody frame components. Solid aluminum rivets provide robust structural connections.
- Providing temporary fastening during vehicle construction. Rivets hold parts in alignment for welding and adhesive bonding. They are later drilled out and replaced.
- Allowing for quick repairs of damaged panels. Riveted panels can be easily replaced rather than requiring full panel welding/bonding.
Rivets meet the demands of automotive manufacturing like automation compatibility, vibration resistance, corrosion resistance, and high-volume installation. Using the optimal rivet type, material, and process for each application results in robust, lightweight, and cost-effective vehicle construction.
Building and Construction
Rivets have been used in buildings and construction projects for well over a century. Early structural steel buildings were assembled using red-hot rivets manually hammered into place. Although welding and bolting are now more common, modern blind and bulb-type rivets continue to be used in construction for the following:
- Permanently joining sheets in metal stud walls, curtain walls, panels, railings, stair stringers etc. Rivets provide a tight clinch and do not loosen over time like screws.
- Assembling prefabricated bridge and building components before transport to the site. The connections allow for quick and easy field installation.
- Anchoring fixtures, pipes, conduit, ducting, railings, and other equipment to steel and aluminum structures. Rivets allow for solid, permanent mounts.
- Building scaffolding, platforms, temporary bridges etc. from modular framework joined with rivets. The structures can be dismantled later by drilling out the rivets.
- Creating decorative metalwork like handrails, grillwork, screens, and cladding. Rivets make attractive visible fasteners for these applications.
- Making field repairs and modifications during and after construction. Rivets can be applied without special tools or welding.
The main advantages of rivets in building and construction are strength, permanence, vibration resistance, and ease of installation. Riveting also requires minimal substrate preparation and avoids heat damage compared to welding. And riveted connections can often be reversed more easily than welds or epoxy if later disassembly is required.
Industrial and Consumer Products
Beyond aerospace, automotive, and construction, rivets are used in a diverse array of industrial and consumer products including:
- Appliances - Rivets clinch the housing sheets and attach components like door hinges, control panels, and vents that require permanent and robust fastening.
- Electronics - Small blind rivets assemble enclosures and mounts for circuit boards, displays, and internal components in computers, phones, and devices.
- Furniture - Riveting is commonly used to join materials in metal and hardwood furniture for a cleaner look compared to screws.
- Outdoor equipment - The assembly of grills, trailers, railings, sheds, and other outdoor items often involves rivets for their vibration resistance.
- Shelving and storage - Rivets provide a simple and inexpensive way to permanently join strips, panels, and gussets in utility and storage shelves.
- Playgrounds - Rivets assemble long-lasting play equipment from tubes, platforms, and pipes that undergo heavy use and abuse.
- Public facilities - Benches, signs, displays, racks, railings and other fixtures at parks, museums, and commercial spaces often use rivets.
- Many DIY projects - Homeowners, craftsmen, and hobbyists use common pop rivets for everything from mending gutters to assembling go-karts.
In these and countless other products, manufacturers select from the wide range of rivet styles, materials, and installation methods to find the optimal fastening solution. The versatility, strength, and cost-effectiveness of riveting make it the ideal assembly method for connecting all sorts of materials in permanent and semi-permanent ways.
The many uses outlined above demonstrate that rivets are one of the most universally useful and important fasteners across countless industries. From aircraft to buildings and computers to jungle gyms, rivets deliver reliable, lightweight, and efficient permanent fastening anytime vibration resistance, strength, and an air-tight clinch are needed. Assembly and product designers continue to find new applications to take advantage of rivets’ unique qualities and evolving installation methods. With the advance of new materials and specialty rivet designs, this simple but profoundly useful fastener will continue improving products and structures far into the future. CNC Milling CNC Machining
