Rivets come in a variety of head shapes, materials, and installation methods to accommodate different applications and design requirements. Some of the most common uses for rivets are outlined below.
Aircraft and Aerospace Applications
Rivets are extensively used in aircraft and aerospace structures. The airframe skin or outer covering of an aircraft is assembled using thousands of rivets. Rivets are preferred for aircraft construction because of their light weight, high strength, and ability to withstand vibration and cyclic loading.
The most commonly used rivets in aircraft are solid and blind rivets made from aluminum alloys, steel, or titanium. Solid rivets require access to both sides of the assembly for installation. Blind rivets can be installed from one side when there is only one-sided access to the work. Other types like cherry rivets and pops rivets are also used in airplanes and spacecraft.
Rivets evenly distribute stress across the joint and keep aircraft panels firmly secured. They are also easily inspected for any cracks or faults. For these reasons, rivets continue to be the primary fastening method in airframe manufacturing.
Rivets are used extensively in the automotive industry for assembling vehicle bodies and frames. The exterior body panels of cars and trucks are usually joined with self-piercing rivets. As the name suggests, these rivets pierce through the metal panels being joined without the need for pre-drilled holes. Self-piercing rivets create very rugged structural joints and can join dissimilar metals.
Blind rivets are the preferred rivet type for automotive interiors. They provide sturdy fastening while allowing easy access for repairs or modifications down the road. Blind rivets come in various grades to withstand different static and dynamic loads. Rivnuts, which are a combination of rivets and nuts, provide strong threaded fastening points for interior components.
Ships and Boats
Marine-grade rivets are used to assemble the hull, decks, and interior structures of ships, speed boats, ferries, and other watercraft. The most common materials for marine rivets include stainless steel, aluminum, and Monel (nickel-copper alloy). These materials have high corrosion resistance against saltwater exposure.
Installing rivets to connect hull plates and frames provides watertight integrity as riveted joints seal out water effectively. Large ships may have over a million riveted connections. The extensive use of rivets makes ship assembly time-consuming but results in incredibly durable vessels with long service lives.
Bridges and Steel Structures
Structural steel construction of bridges, towers, cranes, transmission towers, and roofs involves extensive riveting. Steel sections are joined with hot rivets, which are heated red-hot before insertion. The hot rivet is hammered into its hole and allowed to cool and contract. This creates a very tight joint that can withstand tremendous stresses from dynamic loads.
Cold rivets are also used, but mainly for secondary steel connections. Riveting provides reliable performance at critical structural joints as the joints do not come loose over time. The process also eliminates welding-related issues like distortion. Steel structures around the world rely on millions of rivets for stability and safety.
Rivets are indispensable fasteners in heavy machinery used in agriculture, mining, construction, oil and gas, and other industrial sectors. Large machine components are joined using high-strength structural rivets suitable for transferring dynamic loads and vibration.
Critical piston and shaft connections in engines also rely on rivets. Self-locking rivets that resist loosening due to vibration are ideal for such applications. Industrial machines also use specialty rivets designed to withstand high temperatures, pressures, and corrosive environments.
Appliances and Electronics
Small nickel and aluminum rivets are extensively used in home appliances, computers, mobile devices, and electronics equipment. Appliance panels are commonly joined using pop rivets, which have collars that pop and spread out upon driving to form the rivet head.
Minuscule blind micro rivets secure internal electronics components and circuit boards in computers and consumer gadgets. Using micro rivets instead of solder, epoxy, or screws optimizes weight, strength, and reliability in electronics assembly.
Temporary and Non-Permanent Joints
Rivets need not always make permanent joints. So-called temporary rivets with heads that can shear off at controlled torque levels allow non-permanent connections. Temporary rivets are used when equipment must be periodically disassembled for maintenance or repair.
Tapped rivets filled with screws allow riveted structures to be dismantled and reassembled. Non-structural connections in furniture, signs, and exhibits can be made using drive rivets, which have large shallow domes instead of closed heads. These diverse rivet variants expand the application range.
Product Assembly and Manufacturing
Aside from joining major structural components, rivets also serve as reliable fasteners in diverse manufacturing and product assembly functions. Electrical enclosures, metal housings, valves, and hydraulic cylinders are commonly assembled using standard rivets.
Self-clinching rivets installed by pressing them into pre-drilled sheets are ideal for securing panels, covers, and other hardware. Access to only one side is needed, making assembly efficient. Countersunk rivets provide flush surfaces for smooth finishes. From consumer products to industrial machinery, countless manufactured goods rely on rivets.
Easy Installation and Inspection
Riveting remains popular because it is a simple, low-cost technique with minimal equipment needs compared to welding or bonding. The manual tools used for riveting are inexpensive and portable. Installation just requires access to both sides of a joint, proper alignment, and applying squeezing force.
Presetting tools allow precise control over compression and finishing force during riveting. Riveted joints are also easy to visually inspect for integrity, something difficult in glued or welded joints. These practical factors sustain the prominence of rivets across industries.
In summary, rivets continue to be indispensable fastening components due to their versatility, strength, and ease of use. From tiny electronics to massive aircraft and ships, rivets build robust structures and mechanisms that advance modern technology and transportation. Advancements like self-piercing and blind rivets expand the application scope wider. For key structural joints that must endure extreme conditions, rivets remain the trusted, proven choice. Their uses will continue to grow as manufacturing demands advance. CNC Milling
