What is Blind Riveting Definition and Mechanism Key Features Applications
Have you ever needed to fasten materials where you only have access to one side? That’s where blind riveting comes into play. Blind riveting, commonly known as pop riveting, is a mechanical fastening technique used when the back of the joint is inaccessible.
Definition and Mechanism
Blind riveting involves inserting a hollow rivet with a mandrel through pre-drilled holes in the materials to be joined. Using a specialized rivet installation tool or pop rivet gun, the mandrel is pulled, expanding the rivet body and pressing it firmly against the materials. Once the rivet deforms and clamps the materials, the mandrel breaks off, leaving a secure joint.
Key Features
- Access from One Side Only one side of the workpiece is needed, making it perfect for enclosed or hard-to-reach spaces.
- Quick Installation Rivets can be set rapidly with hand tools or pneumatic tools, boosting productivity.
- Wide Material Compatibility Commonly used on metals, plastics, and composites.
- Corrosion Resistance Available in aluminum, stainless steel, and other corrosion-resistant materials.
- Vibration and Shock Resistance The blind rivet provides steady, reliable fastening under stress.
Applications
Blind riveting is widely used across industries, including:
- Automotive Fastening panels and components where backside access is limited.
- Aerospace Attaching thin sheet metal panels and lightweight assemblies.
- Construction Joining sheet metal, roofing, and cladding materials.
- Electronics and Appliances Fastening enclosures and housings efficiently.
- Sheet Metal Fabrication Ideal for CNC machining fasteners in complex assemblies where speed and accessibility matter.
Blind rivets offer a practical and versatile solution when traditional solid riveting is not possible. Companies like HYCNC provide specialized CNC services to manufacture high-quality blind rivets suited for demanding applications in the US market.
What is Solid Riveting
Solid riveting is a traditional mechanical fastening method that uses a solid metal pin called a rivet to join two or more materials together. Unlike blind riveting, solid rivets require access to both sides of the materials being joined for installation. The rivet is inserted through aligned holes in the workpieces and then deformed or “upset” at the tail end by hammering or pressing to create a strong, permanent joint.
Mechanism
The solid rivet works by expanding the tail end to form a second head, locking the materials tightly together. This deformation process typically requires specialized tools such as pneumatic hammers, bucking bars, or CNC riveting machines. The solid nature of the rivet makes the joint exceptionally strong and resistant to shear and tensile forces.
Key Features
- Requires access to both sides of the workpieces
- Creates very strong, permanent joints
- Usually made from aluminum, steel, or copper alloys
- Can handle high-stress and heavy-duty applications
- Installation often involves specialized equipment
Applications
Solid riveting is widely used where maximum strength and durability are critical. Typical industries include:
- Aerospace: fastening aircraft skins and components
- Automotive: chassis and frame assembly
- Structural steel: bridges and heavy machinery
- Shipbuilding: hull and deck riveting
This method is preferred in applications where reliability and long-lasting joints matter most, especially in structural and safety-critical parts.
Blind Riveting vs Solid Riveting Key Differences
When it comes to choosing between blind riveting and solid riveting, understanding their core differences helps you pick the right fit for your project.

Strength and Durability
- Solid Rivets offer higher strength and are more durable, especially for heavy-duty applications like aerospace and automotive structural riveting. They handle stress and vibration better.
- Blind Rivets are generally less strong but good enough for lighter or medium-duty loads where ease of installation is a priority.
Cost and Efficiency
- Blind Riveting tends to be more cost-effective considering installation time and labor, especially for jobs where speed matters. Rivet installation tools for blind rivets are often simpler and less expensive.
- Solid Riveting can be costlier due to labor intensity, tooling, and sometimes the need for CNC machining fasteners or specialized equipment.
Accessibility and Versatility
- Blind Rivets excel in tight spaces or when only one side is accessible, making them very versatile across industries like sheet metal fabrication and general mechanical fastening.
- Solid Rivets are best if you need superior strength and have easy access to both sides of the material.
Quick Comparison Table
| Feature | Blind Riveting | Solid Riveting |
