Rivets come in an enormous range of types, sizes and materials to suit nearly any application. Let's take a look at some of the many uses for this ubiquitous fastener.
Aircraft and Aerospace Applications
Aircraft construction has always relied heavily on rivets due to their light weight, high strength and reliable performance. Early aircraft used solid aluminum rivets, but most modern aircraft now use blind rivets. These are installed by tools that access only one side of the work, avoiding the need to buck the protruding end. Blind rivets make for faster assembly and a smoother surface.
High-strength steel rivets see heavy use in critical areas like wing spars and landing gear. Titanium and specialty aluminum alloys meet needs for both strength and light weight. Drive rivets that lock by mechanically upsetting the driving collar are common for securing nonstructural parts. And specialty rivets like the countersunk Cherry rivet provide optimal performance in particular applications.
Rivets also find ubiquitous use in space vehicles and satellites. In the hard vacuum of space, they exhibit none of the loosening problems caused by vibration and temperature cycling in an atmosphere. Rivets provide safe, reliable, and maintenance-free fastening over the long service life required for space hardware.
Construction and Infrastructure
The versatility of rivets makes them popular for connecting structural elements in buildings, bridges, towers, and civil infrastructure. Steel rivets were the traditional choice, but bolting has largely superseded riveting for structural steel construction. However, rivets still see substantial use in joining gusset plates, bracing angles, and specialized connections.
Blind rivets offer similar advantages to construction as they do in aircraft: they're quick and easy to install in tight spaces and produce a smooth surface. Roofing, siding, HVAC ducting, electrical conduit, plumbing, and many other building systems rely extensively on blind rivets and other specialty rivet types. Stainless steel and aluminum rivets resist corrosion in demanding environments. And large structural rivets provide the needed strength for critical connections.
Cars and trucks contain thousands of rivets in their body panels, frames, interiors, and subsystems. Blind rivets are especially popular for automotive assembly because access is often only available from one side when joining interior or overlapping exterior body panels. Self-piercing rivets drill through stacked sheet metal layers in one operation to simplify assembly.
High-strength steel and aluminum rivets meet automotive structural requirements. Drive rivets provide clamping power where vibration resistance is critical. And specialized rivet types secure wiring harnesses, HVAC components, seats, trim, and countless other vehicle parts. Automotive designers select rivets wherever they provide the optimum combination of fast assembly, strength, and economy.
Appliances and Consumer Goods
Rivets deliver reliable, inexpensive fastening for connecting sheet metal housings and frames in appliances, electronics, furniture and hundreds of other products we use every day. The convenience and low cost of rivets make them a first choice for consumer goods assembly. Blind rivets enable easy installation where access is confined. Self-piercing and semi-tubular rivets clinch sheet metal layers together in one fast operation.
Aluminum and steel rivets have the strength to handle demanding structural joints. But lightweightDRIVE rivets also secure non-critical components while minimizing product weight. Countersunk and specialty head rivets produce a smooth exterior surface and appealing look. And with plenty of rivet options in almost any color, it's easy to match or accent the product's aesthetics. Next time you use a refrigerator, mixer, PC, furniture or other consumer product, think about all the great features made possible by simple and versatile rivets!
Marine and Subsea Applications
The marine environment is one of the most corrosive and demanding for mechanical fasteners. Stainless steel rivets withstand saltwater corrosion over decades of service aboard ships and offshore platforms. High-strength aluminum rivets meet the marine industry's structural requirements with the benefit of weight savings. Blind rivets enable quick and easy watertight sealing of hull compartments. And custom rivets are designed specifically for securing critical marine systems and subsea equipment.
Rivets offer reliable fastening performance even under extremely high pressures in deep submersible, remotely operated and autonomous underwater vehicles. No loosening from vibration and resistant to corrosion, they outperform many other fastener types for underwater use. Next time you see an ocean research vessel or naval submarine, know that it probably depends on thousands of specialty rivets to handle its unique demands below the waves.
Everyday Repair and DIY Projects
For those who enjoy tinkering and repairing mechanical devices, rivets provide an easy way to fabricate and fix things with basic hand tools. Pop rivets allow anybody to quickly join metals without bucking or accessibility to both sides - a real advantage in tight confines. Home hobbyists, repair technicians and makers find countless uses for rivets in restoring machinery, modifying equipment, and bringing their creative visions to life.
Rivets come in all popular sizes and materials for DIY projects. Buy them individually at the hardware store or in economical bulk packs online for your workshop. With just a rivet gun, hammer or even pliers, you can securely fasten parts and perform repairs. Next time something needs fixing or improving at home, reach for tried and true rivets to get the job done right.
The Universal Fastener
As this overview illustrates, rivets have endured as an essential fastening method after centuries of technological progress. From ancient iron bridges to modern satellites, rivets solve innumerable fastening and assembly problems. Their versatility, strength, durability and ease of use make them universally useful across industries and applications.
