Rivets are a simple yet ingenious fastening system that has been used for thousands of years. In the modern world, rivets continue to play an integral role in manufacturing, construction, and engineering. Though often overlooked, rivets possess distinct advantages that make them a preferred choice over other types of fasteners in many applications.
What are Rivets?
A rivet is a mechanical fastener that consists of two main parts - a smooth cylindrical shaft and a head. The shaft is inserted into holes in the materials being joined and the head is mushroomed or bucked to secure the rivet in place using a riveting hammer, creating a permanent joint. The malleable head flows into a specially countersunk hole, forming a secondary head and clamping the materials together.
Rivets come in a variety of styles, materials, and head shapes to accommodate different design requirements and installation methods. Common types include solid rivets, semi-tubular rivets, blind rivets, and drive rivets. Aircraft-grade aluminum is the most popular rivet material, but they are also made from steel, copper, stainless steel, and titanium.
Benefits of Rivets
There are several key reasons rivets continue to be ubiquitous in manufacturing and construction:
- Strong and Reliable: The riveting process work-hardens the rivet material, creating an incredibly strong joint. Properly installed rivets withstand vibration, shock, and tensile loads.
- Permanent Fastening: Unlike screws or bolts, rivets form a permanent connection that won't come loose over time.
- Streamlined Installation: Riveting is a fast and relatively simple process suitable for automation and mass production assembly lines. Minimal hardware and tooling is required.
- Corrosion Resistant: Aluminum and stainless steel rivets provide corrosion resistance and withstand harsh environments.
- Cost Effective: Rivets are inexpensive compared to welding or proprietary fasteners. Only basic tooling is needed for installation.
- Lightweight: Rivets add very little weight, an important consideration in aircraft and automobile manufacturing.
- Low Profile: The smooth and flush rivet head has minimal impact on the materials being joined.
- Versatile Materials: Rivets can join dissimilar or thin materials like plastics and composites. Special rivets are even used in jewelry making.
Key Uses of Rivets
Aircraft and Aerospace Applications
The light weight, high strength, and reliability of rivets make them the primary fastener used in aircraft assembly. Literally millions of rivets are used to join aluminum fuselage skins, wings, engine nacelles, flight control surfaces, landing gear, and other components. Riveting allows complex, contoured assemblies while minimizing weight. Specialty rivets like flush head and countersunk are extensively used.
Automotive Manufacturing
Riveting is the preferred assembly method in automotive manufacturing. The chassis, exterior body panels, doors, hood, and roof are commonly joined with rivets. Pop rivets allow quick fastening of interior trim, seats, and components. Rivets withstand the vibration and harsh conditions seen by cars and trucks while permitting controlled crumple zones for safety.
Appliances and Electronics
The sheet metal casings of appliances and electronics often utilize rivets for clean and sturdy construction. The speed and automation potential of rivets allows high-volume production. Blind rivets are ideal where access is limited for assembly. Pop rivets let components be serviced or replaced quickly during repairs.
Construction and Infrastructure
Rivets secure steel beams, girders, rail tracks, rebar, pipes, and mechanical items in the built environment. Their high shear strength makes them ideal for structural connections subject to loads. The permanence of rivets prevents loosening over time from vibration or temperature fluctuations. Riveted connections are also used for aesthetic purposes in exposed architectural metalwork.
Industrial Machinery
Heavy machinery and equipment is riveted together due to the technique's reliability and safety. Mining gear, bulldozers, cranes, agriculture equipment and more operate in harsh, dirty, and high load environments. Rivets maintain integrity through prolonged use where bolts and screws would fail. They also better withstand extreme heat and cold.
Marine grade rivets withstand constant humidity, saltwater, and waves. They are used extensively in the assembly of barges, ferries, cargo and container ships, cruise ships, naval vessels. Riveting remains the preferred construction method as it dampens vibration and prevents metal fatigue cracking. Rivets also don't loosen over time despite shifting cargo loads.
Rail Industry
Rivets provide a robust, permanent fastening method for railroad tracks, railway cars, locomotives, and mass transit vehicles. The bumpy ride and heavy loads exert tremendous forces that rivets can withstand where other fasteners may back out or fail over time. Riveted bogies, couplers, and assemblies prevent derailments and ensure passenger safety.
Everyday Items
Rivets appear in all types of common products for durability and safety. Jeans have copper rivets so the seams don't split. Pocket knives use rivets so the knife doesn't fold or come apart while in use. Zippers rely on rivets to attach the teeth to the tape edges. Camping gear uses rivets to assemble frames that support weight and stress. They are also used in musical instruments, cookware, furniture and more.
Rivets Continue to Excel
From aircraft and bridges to blenders and blue jeans, it's clear rivets continue to excel at joining materials in a vast array of manufacturing and construction applications. Their versality, strength, permanence, and reliability make them a hard fastener to beat. Advancements in installation methods and specialty rivet designs ensure they maintain their prominence wherever high-quality, durable connections are required.
