Rivets are a ubiquitous fastening hardware used across countless industries to join and assemble materials. Though simple in design, consisting of a smooth cylindrical shaft and head, rivets serve an invaluable role in manufacturing, construction, aeronautics, and beyond. Understanding the functionality and variety of rivet types enables selecting the optimal rivet for an application.
A rivet works by inserting the shaft through pre-drilled holes in the materials being joined. The excess shaft is then removed and the rivet head is upset, or deformed, with force to flare out and secure the rivet in place. This creates a permanent mechanical bond. The flaring effect of the rivet head is a distinct advantage over screws and bolts, as it joins materials firmly without relying on friction or threading.
Rivets come in an extensive range of sizes, materials, and styles to accommodate different demands:
Blind Rivets
Blind rivets can be installed where access is only available to one side of a workpiece. The rivet has a built-in stem that is pulled to deform the rivet. Blind rivets are popular in aerospace applications.
Tubular Rivets
One of the most common types, tubular rivets have a hollow cylindrical body. Used with a bucking bar on the backside during installation for accessibility.
Solid Rivets
As the name describes, solid rivets have a solid versus tubular shaft. Used for applications where a rivet needs to fill a hole entirely.
Structural Rivets
Structural rivets are an extra heavy-duty variant designed for joining structural building components or demanding high-stress applications.
Drive Rivets
Drive rivets have a rounded head that requires a tool specialized to form the head during installation. This allows flush setting versus other rivet types.
Self-Piercing Rivets
As implied, self-piercing rivets do not need pre-drilled holes. The rivet pierces and displaces material as it is driven in using tremendous force. Ideal for joining dissimilar or soft materials.
Aluminum Rivets
One of the most popular rivet types, aluminum is lightweight, corrosion resistant, and strong. Ideal for aircraft and marine applications.
Steel Rivets
Made from steel alloys, steel rivets offer very high shear strength. Used for high-stress connections. Prone to corrosion if not properly sealed or maintained.
Stainless Steel Rivets
These rivets combine the strength of steel with corrosion resistance. Used extensively in corrosive or marine settings. More expensive than other metal types.
Plastics Rivets
Rivets made from engineered plastics like nylon are useful for applications where corrosion resistance and electrical or thermal insulation are needed. Not as strong as metal rivets.
The multitude of rivet styles and materials allows manufacturers to select optimized rivets depending on factors like strength needs, corrosion resistance, and accessibility during installation. Some of the most common applications for various rivet types include:
Aircraft Assembly - Rivets are universally used in aircraft construction to assemble fuselages, wings, and other components. The aviation industry relies heavily on specialty rivets like blind, oval head, and high shear rivets.
Metal Building Construction – Self-piercing and tubular rivets are often used for rapid joining of structural steel I-beams, girders, and corrugated roofing. Riveting is a cleaner and faster alternative to welding.
Boat and Ship Building – Marine grade stainless steel rivets are ideal for boat hull assembly as they resist corrosion from constant water exposure. Rivets allow ship segments to be pre-assembled in sections.
Automotive Manufacturing – Self-piercing and blind aluminum rivets efficiently join auto body panels like hoods, doors, and trunk lids. Plastics rivets also fasten interior components like dashboards.
Construction Equipment - Heavy machinery relies on enormous solid steel rivets for critical structural joints to handle high dynamic loads and impact forces.
HVAC Ductwork – Sheet metal screws used to assemble ductwork often loosen over time. Tubular rivets provide a permanent alternative for connecting duct sections.
Appliances – Manufacturers of washers, dryers, dishwashers, refrigerators, etc. all rely on rivets for assembling sheet metal housings and attaching components internally.
Electronics – Small tubular aluminum rivets mount circuit boards and assemble electronic device housings like computers, routers, and keyboards.
The versatility of rivets stems from variability in head shape, shaft diameter and length, material strength and corrosion resistance, and installation technique. While screws, bolts, welds, and adhesives join materials too, rivets offer a balanced blend of strength, speed, and practicality that makes them the preferred choice in numerous applications.
Continuous innovation also expands rivet utility and performance. For example, new structural rivet designs allow joining thicker and stronger materials than ever before. Self-piercing rivets eliminate the need for pre-drilled holes to permit faster assembly. Plastics rivets improve corrosion resistance and insulation versus traditional metal variants.
In summary, rivets deliver an unmatched combination of portability, affordability, shear and tensile strength, vibration resistance, and ease of installation. Their versatility ensures rivets will remain an essential assembly hardware across manufacturing, construction, transportation, and electronics for the foreseeable future. Whether an aluminum aircraft rivet, stainless steel ship rivet, or nylon appliance rivet, rivets meet the joint fastening needs of modern engineers and builders around the globe. CNC Milling
