What Is a Rivet? Basic Overview & Working Principle
Definition of Rivet
A rivet is a permanent mechanical fastener consisting of a standardized head, smooth cylindrical shank, and deformable tail. Unlike detachable bolt and nut connections, rivets form an integrated fixed structure through tail deformation after installation, realizing permanent, stable, and anti-loosening assembly between two or more parts. Common raw materials for industrial rivets include aluminum, carbon steel, stainless steel, brass, and copper, covering almost all metal and partial non-metal assembly scenarios.
How Do Rivets Work in Industrial Assembly?
The 2026 standardized riveting process is adapted to automated production lines, featuring stable and efficient operational steps. The core working principle remains consistent: first, drill a reserved hole 1.5mm larger than the rivet shank diameter to ensure accurate insertion and assembly clearance; then insert the rivet into the aligned hole, and deform and flatten the tail using pneumatic rivet guns, hydraulic equipment, or manual hammering. The deformed tail expands to approximately 1.5 times the original shank diameter, forming a new fastening head—similar to a dumbbell structure—to securely lock the assembled parts, achieving a permanent anti-loosening and pressure-resistant connection.
Different from traditional threaded fasteners, riveting relies on mechanical deformation extrusion force for fixing, without thread loosening risk, and has stronger stability in long-term vibration and high-load working environments.
Core Advantages & Disadvantages of Rivet Fasteners
Rivets are widely used in industrial manufacturing because of their unique structural advantages, but they also have inherent limitations compared with welding and bolting. Reasonable selection based on project scenarios can maximize assembly efficiency and quality.
Key Advantages of Rivets

: Most blind rivet products support single-sided construction, solving the assembly difficulty of narrow spaces and inaccessible back-end structures, which cannot be realized by traditional bolt fastening.
- Cost-Effective for Mass Production
: Riveting process has low comprehensive cost, simple supporting tooling, and no complex matching parts. It is more economical than bolted connection in large-scale standardized assembly projects.
- Strong Vibration & Wear Resistance
: The integrally deformed rivet structure has no gaps and thread clearance, effectively resisting long-term mechanical vibration, friction and impact, ensuring long-term stable connection strength.
- Wide Application Versatility
: Customizable in multiple sizes, structures, and materials, rivets can match metal, plastic, leather, wood and other materials, covering light daily assembly and heavy structural engineering.
Main Disadvantages of Rivets
- Compared with welding, riveting requires pre-drilling and positioning procedures, consuming more labor and time costs with lower overall efficiency.
- Rivet joints are heavier than welded and brazed joints due to the existence of rivet bodies and gaskets, which has slight limitations in ultra-lightweight extreme scenarios.
- The riveting process produces obvious noise, requiring noise reduction measures in closed production workshops.
- Ordinary riveting structures cannot achieve complete airtight and leak-proof effects, and are not suitable for high-pressure sealing equipment assembly.
- Rivet connections are permanent structures, difficult to disassemble and repair, increasing maintenance costs for equipment that requires frequent debugging.

This unique performance makes brass rivets specially used in gas equipment, explosion-proof hardware, and precision decorative assemblies, meeting safety standards for special industrial environments.
5. Copper Rivets
Copper has excellent thermal and electrical conductivity, with good flexibility and fitting performance. Copper rivets are mainly used for electrical equipment conductive connection, water supply and drainage hardware, and heat dissipation component assembly, ensuring stable electrical conduction and heat transfer efficiency.
7 Main Types of Rivets: Structure, Features & Industrial Uses
According to structural differences and installation methods, industrial rivets are divided into seven mainstream types, each with exclusive application scenarios. Accurate type selection is the key to improving assembly quality and reducing costs.
1. Solid Rivets (Most Reliable Structural Rivets)
Solid rivets are the most traditional, common, and high-reliability fasteners, composed of integrated solid shanks and fixed heads (round head or 100° countersunk head). They require double-sided operation for installation, with strong shear resistance and structural stability. Widely used in safety-critical scenarios such as aircraft structural parts, heavy machinery, bridge engineering, and automotive load-bearing components, they are the first choice for heavy-duty permanent assembly.
2. Blind Rivets (Pop Rivets)
Also known as hollow rivets, blind rivets consist of tubular shells and central mandrels. The biggest advantage is single-sided installation, suitable for invisible and inaccessible assembly positions. During installation, the tail expands and the mandrel breaks off to form a stable lock. They are widely used in aerospace, electronic equipment, shipbuilding, and sheet metal assembly. Common subtypes include pull-mandrel rivets, threaded rivet nuts, and drive-pin rivets, covering light, medium, and heavy-duty assembly needs.
3. Tubular Rivets
Tubular rivets have a hollow tail structure, requiring low installation pressure and good ductility. They are divided into full tubular, semi-tubular, and compression tubular rivets. Semi-tubular rivets have moderate strength, similar to solid rivets after forming; full tubular rivets are suitable for soft materials such as fabric and plastic; compression tubular rivets are used for double-sided aesthetic assembly of soft parts. They are mostly applied in commercial hardware, daily necessities, and light industrial products.
4. Split Rivets (Bifurcated Rivets)
Split rivets have split and sharp tail structures, which can self-pierce soft materials without pre-drilling. They are suitable for low-load assembly of leather, wood, plastic, and other materials, commonly used for home maintenance, craft decoration, and light hardware connection. Not applicable for high-precision and high-load industrial structural parts.
5. Flush Rivets (Countersunk Rivets)
Flush rivets adopt a countersunk head design, which can be completely flush with the part surface after installation, eliminating surface protrusions. They effectively reduce aerodynamic resistance and surface turbulence, and are mainly used for aircraft exterior panels, high-precision equipment shells, and appearance parts requiring flatness and aesthetics, meeting aerodynamic and high-grade appearance standards.
6. Self-Piercing Rivets
Self-piercing rivets have chamfered sharp tails, realizing one-time piercing and riveting without pre-drilling. They penetrate the upper material and half-clamp the lower material to form a tight waterproof and airtight structure. With excellent column strength and high assembly efficiency, they are widely used in automotive lightweight parts and composite material assembly.
7. Friction Lock Rivets
Friction lock rivets are improved blind rivets with cup-shaped or countersunk structures. The shank automatically breaks under set tension, forming a friction self-locking structure. They feature stable clamping force and strong fatigue resistance, specially used for light aircraft maintenance and high-precision aerospace component assembly.
