Types of Rivets
Different rivet types for different applications: 1. Solid Rivets: - Traditional rivet requiring access to both sides - Requires bucking bar for installation - Highest strength for critical applications - Used in: Structural, aerospace, shipbuilding 2. Pop Rivets (Blind Rivets): - Installed from one side only - Mandrel breaks off during installation - Various materials: aluminum, steel, stainless - Most common for general applications 3. Structural Blind Rivets: - Higher strength than standard pop rivets - Large flange for load distribution - Used in: Automotive, transportation 4. Specialized Rivets: - Drive rivets (single-sided) - Rivet nuts (creates threads) - Self-piercing rivets (for sheet metal)
Rivet Selection
Key factors for rivet selection: 1. Grip Range: - Total thickness being joined - Must fit within rivet grip range 2. Material: - Aluminum rivets: Light weight, general use - Steel rivets: Higher strength - Stainless rivets: Corrosion resistance 3. Head Style: - Dome head: Standard appearance - Countersunk: Flush mount 4. Hole Size: - Typically 0.1mm larger than rivet diameter - Too tight = difficult installation - Too loose = weak joint
