Riveting is one of the oldest permanent metal fastening technologies in human history, with origins dating back thousands of years to ancient bronze and iron working. For much of the Industrial Revolution and the early 20th century, rivets were the dominant structural fastening method, used to build iconic steel bridges, skyscrapers, battleships, and the first generation of commercial aircraft. Today, however, many engineers, fabricators, and industry observers ask: why is riveting no longer used?
The short answer is that riveting has not disappeared entirely - but its common use has declined dramatically across most industrial sectors, displaced by faster, cheaper, and more automation-friendly fastening technologies. Traditional hot-driven solid rivets, once ubiquitous in heavy construction and shipbuilding, are now relatively rare, while modern rivet variants remain niche solutions for specific high-performance applications.
In this guide, we break down the key reasons for riveting's decline in mainstream manufacturing and construction, compare the technologies that have replaced it, and explore the critical industrial sectors where riveting still remains an irreplaceable fastening solution.
The Golden Age of Riveting: Why It Once Dominated Industry
Before exploring its decline, it is important to understand why riveting became the standard for structural fastening for over a century. Prior to the widespread adoption of reliable electric arc welding and high-strength threaded fasteners in the mid-20th century, hot-driven solid rivets offered unmatched advantages for heavy structural assembly:
- Proven structural reliability: When installed correctly, hot rivets create a tight, preloaded joint as the heated metal cools and contracts, delivering excellent shear strength and fatigue resistance under cyclic and vibratory loads.
- Material compatibility: Early 20th-century steel grades were well-suited to hot riveting, and the process produced consistent, inspectable joints with relatively simple quality control.
- On-site practicality: Early construction sites often lacked reliable electrical power, making hot riveting - which relied on portable forges and pneumatic hammers - a viable on-site fastening solution.
From the Eiffel Tower and the Golden Gate Bridge to World War II-era liberty ships and early Boeing airliners, rivets were the backbone of modern industrial construction. Their decline began in the post-WWII era, driven by six interconnected technological and economic shifts.
6 Key Reasons Riveting Declined In Mainstream Industry
1. High Labor Costs and Skilled Worker Scarcity
Traditional hot riveting is an extremely labor-intensive process that requires a highly skilled crew. A standard riveting team requires at least two workers: one to hold a bucking bar against the preformed head on the back side of the joint, and one to drive and form the opposite head with a pneumatic hammer or press. For hot riveting, an additional worker heats rivets in a portable forge and passes them to the installation team.
As industrial labor costs rose dramatically in the second half of the 20th century, and the pool of skilled riveters shrank as older workers retired, riveted joints became increasingly uncompetitive compared to welding and bolted connections, which require less specialized labor and can be performed by fewer workers.
2. The Rise and Maturation of Modern Welding Technology
The single biggest factor in riveting's decline was the rapid advancement of electric arc welding technologies - including shielded metal arc welding (SMAW), MIG, TIG, and eventually robotic automated welding - between the 1930s and 1960s.
Early welding processes suffered from inconsistent quality, porosity, and structural reliability issues, which made rivets the safer choice for critical structural work.
By the post-WWII era, however, welding technology had improved dramatically:
- Welded joints can match or exceed the shear and tensile strength of riveted joints when executed correctly.
- Welding requires access to only one side of the joint in most applications, eliminating the need for a bucking bar worker.
- Welding is significantly faster than riveting for large structural assemblies, reducing overall project timelines.
By the 1960s, welding had replaced riveting as the default structural fastening method for shipbuilding, steel construction, and heavy machinery manufacturing.
3. High-Strength Threaded Fasteners and Bolted Connections
Parallel to advances in welding, the development of standardized high-strength alloy steel bolts - including ASTM A325 and A490 structural bolts - provided another viable alternative to rivets for heavy construction.
Bolted connections offer several decisive advantages over riveted joints:
- Removability and maintainability: Bolts can be easily tightened, loosened, and replaced for maintenance, repair, or equipment disassembly. Rivets, by contrast, are permanent and must be drilled out to disassemble a joint, a process that can damage the base material.
- Faster installation: Structural bolts can be installed with a single worker using a torque wrench, with no heating or bucking bar required.
- Consistent quality control: Bolt tension can be verified with torque or tension testing, making quality assurance more straightforward and reliable than visual inspection of rivet heads.
For prefabricated steel construction, in particular, bolted connections became the standard, as they allow for fast, predictable on-site assembly of prefabricated steel components.
4. Demand for High-Volume Automated Manufacturing
The rise of mass production in the automotive, appliance, and electronics industries created demand for fastening technologies that could be fully automated and operate at high cycle times.
Traditional solid riveting is difficult to automate fully, especially for complex 3D assemblies, and is too slow for high-volume production lines. While semi-tubular rivets and blind rivets can be automated, they face stiff competition from faster alternatives:
- Robotic spot welding for automotive body assemblies
- Self-clinching fasteners for sheet metal electronics enclosures
- Adhesive bonding and structural tapes for lightweight assemblies
- Snap-fit and interlocking sheet metal designs that eliminate fasteners entirely
For modern lean manufacturing operations focused on minimizing cycle time and per-unit cost, riveting is rarely the most efficient option for general-purpose assembly.
5. Evolution of Engineering Materials
Traditional hot riveting was developed for carbon steel, the dominant structural material of the early 20th century. Modern industrial design increasingly uses advanced materials that are poorly suited to hot riveting:
- Aluminum alloys: Widely used in aerospace and automotive lightweighting, aluminum can be riveted, but hot riveting risks warping and material degradation. Cold riveting and specialized blind rivets are used, but adhesive bonding and mechanical fastening are often preferred.
- High-strength steels: Modern advanced high-strength steels (AHSS) are harder and more brittle than traditional mild steel, making them more difficult to rivet without specialized equipment.
- Composite materials: Carbon fiber, fiberglass, and polymer composites cannot be hot riveted at all, as the heat would destroy the material matrix.
As these materials have become more common, the addressable market for traditional riveting has shrunk accordingly.
6. Environmental and Workplace Safety Regulations
Hot riveting involves open flames, high-temperature metal, loud pneumatic tools, and significant ergonomic strain on workers. As workplace safety regulations tightened in the late 20th century, and companies prioritized reducing workplace injuries and environmental hazards, hot riveting became increasingly unattractive compared to cleaner, safer alternatives like welding (with proper fume extraction) and bolted assembly.
Riveting Is Not Dead: Where It Remains Critical
Despite its decline in mainstream manufacturing, riveting is far from obsolete. In several high-stakes industrial sectors, rivets remain the preferred or only viable fastening solution.
1. Aerospace and Aviation
- Commercial and military aircraft are still held together by millions of rivets - mostly solid aluminum and titanium rivets, plus specialized structural blind rivets. The reason is simple: rivets offer unmatched fatigue resistance under the constant cyclic pressurization and aerodynamic loads that aircraft fuselages and wings endure. Welded aluminum joints are prone to fatigue cracking, making rivets the safer, more reliable choice for aerospace structures.
2. Historical Structure Restoration and Heritage Construction
- For historic steel bridges, landmark buildings, and heritage industrial structures, restoration projects are required to match the original construction methods to preserve structural integrity and historical authenticity. Hot riveting is still used by specialized restoration teams to repair and replace riveted joints on iconic 19th and early 20th-century steel structures, as welding or bolting would compromise the historical design.
3. Heavy-Duty Material Handling and Industrial Machinery
- In high-vibration, high-impact heavy equipment - including forklifts, construction machinery, mining equipment, and agricultural implements - riveted joints still offer advantages over bolted connections, which can loosen over time under constant vibration. Permanent riveted joints maintain consistent clamping force for decades, reducing maintenance requirements and improving equipment reliability.

Modern Rivet Innovation: Adapting to 21st-Century Manufacturing
Rivet technology has not stood still. While traditional solid hot rivets have declined, advanced rivet variants have carved out new niches in modern manufacturing:
- Self-piercing rivets (SPR): Specially designed rivets that pierce through sheet material without pre-drilled holes, ideal for automated assembly of aluminum and mixed-material automotive body structures.
- Structural blind rivets (lockbolts): High-strength blind rivets that lock the mandrel permanently into the rivet body, delivering strength approaching solid rivets with single-sided installation - widely used in truck chassis and bridge repair.
- Automated riveting systems: CNC-controlled robotic riveting machines used in aerospace manufacturing that deliver consistent, high-speed rivet installation for large aircraft structures.
These innovations ensure that riveting technology continues to evolve and remain relevant for specialized high-performance applications, even as it fades from general-purpose use.
Conclusion
So why is riveting no longer used? The reality is that riveting has not disappeared - it has simply been demoted from a universal default fastening method to a specialized solution for specific use cases. The decline of traditional hot riveting was driven by fundamental economic and technological shifts: rising labor costs, the maturation of welding and high-strength bolts, the demand for automated mass production, and the evolution of advanced engineering materials.
For most general-purpose manufacturing and construction applications today, welding, bolting, or adhesive bonding will be more efficient, cost-effective, and practical than riveting. However, for critical applications where fatigue resistance, vibration immunity, permanent fastening, or historical authenticity is paramount, riveting remains an irreplaceable technology - and one that continues to advance alongside modern manufacturing methods.
For engineering and procurement teams, the key is to avoid assuming riveting is obsolete, and instead evaluate each application on its own merits to select the fastening technology that delivers the best balance of strength, cost, durability, and manufacturability.
