Blind Rivets (POP Rivets)
Overview
Blind rivets (commonly known as POP rivets) are a reliable permanent fastening solution used where welding or soldering would negatively affect the material structure.
They are widely used in:
- Mechanical engineering
- Instrumentation
- Light industry
- General construction and DIY applications
Riveted joints provide high strength, durability, and tamper-resistant connections, making them ideal where disassembly is not required.
Construction and functions
A blind rivet consists of two main components:
- Rivet body – forms the permanent joint
- Mandrel (pull stem) – used to deform and set the rivet
This fastening method is ideal for joining two or more sheet materials, including:
- Steel
- Aluminum
- Plastics
- Leather
Materials
Blind rivets are available in various material combinations:
- Aluminum / Aluminum
- Aluminum / Steel
- Aluminum / Stainless steel (A2 / AISI 304)
- Stainless steel / Stainless steel (A2, A4 / AISI 316)
- Steel / Steel
- Copper / Steel
- Copper / Bronze
Material selection should consider:
- Mechanical strength
- Electrochemical corrosion compatibility
- Aesthetic requirements
Key features and Advantages
- Permanent, high-strength fastening
- Resistant to vibration and mechanical loads
- Long service life
- Suitable for applications without access to the reverse side
- Fast and efficient installation
-
Performance characteristics depend on:
- Head type
- Clamping force
- Mandrel retention
- Hole-filling capability
- Blind-side expansion
- Sealing performance (watertightness)

Monobolt & Interlock Rivets
Designed for demanding applications:
- High shear and tensile strength
- Excellent hole-filling capability
- Wide grip range
- Strong vibration resistance
- Reduced risk of water ingress
- Permanent mandrel retention
-
Note: Monobolt rivets may require a special installation tool.
Selection Consideratioins
Proper rivet selection is critical to ensure strength and sealing performance. Key parameters include:
- Rivet diameter
- Hole size
- Grip range (material thickness)
- Head type
- Required strength (shear and tensile values)
Incorrect sizing may result in reduced performance or joint failure.
