Rivets

1. Overview

Rivets are mechanical fasteners with a cylindrical shaft and head, used to permanently join materials by deforming the tail end. Their simplicity, vibration resistance, and structural reliability make them essential in aerospace, automotive, construction, and electronics industries.

2. Major Types & Functional Classification

Type	Functional Features	Application Examples
1. Solid Rivets	High shear strength, permanent installation	Aerospace structural joints
2. Blind Rivets	Single-side installation capability	Enclosed panel assembly
3. Split Rivets	Flexible tail expansion for soft materials	Leather goods and plastic
4. Drive Rivets	Low-profile design with high pull-out resistance	Sheet metal ductwork
5. Structural Rivets	Optimized for load-bearing applications	Bridge construction

3. Structure & Composition

Typical rivet structure includes: - Head (manufacturing head, bearing surface) - Shaft (smooth or threaded cylindrical section) - Tail (deformable end for mating surface) Materials: Aluminum alloys (2024-T4), Steel (A108), Stainless Steel (304/316), Monel, Plastic (Nylon 66)

4. Key Technical Specifications

Parameter	Significance
Diameter (2-8mm standard)	Determines shear/bearing capacity
Length (4-50mm range)	Material thickness compatibility
Material Strength (414-1034MPa)	Load-bearing capability
Corrosion Resistance (ASTM B488)	Environmental durability
Installation Force (1.5-15kN)	Tooling requirements

5. Application Fields

Aerospace: Wing assembly (Boeing 787 uses 50k+ titanium rivets)
Automotive: Frame rail connections (Ford F-150 aluminum body)
Construction: Steel beam connections (New York Freedom Tower)
Electronics: PCB grounding (Apple MacBook Pro chassis)

6. Leading Manufacturers & Products

Manufacturer	Representative Products
B llhoff Group	POP Avdel aerospace rivets
Southco	Flush head composite rivets
Emhart Tek	Multi-grip blind rivets
Cherry Aerospace	MaxiLOK structural rivets

7. Selection Recommendations

Key considerations: 1. Material compatibility (aluminum vs. stainless steel) 2. Joint thickness requirements 3. Environmental exposure (marine vs. industrial) 4. Installation access (single-side vs. double-side) 5. Certification requirements (NASM8000 series for aerospace)

8. Industry Trends

Emerging developments include: - Self-piercing rivets eliminating pre-drilling (Tesla Model Y uses 30% SPR) - Smart rivets with embedded strain sensors - Bio-resorbable polymer rivets for medical implants - Automated robotic riveting systems achieving 120 rivets/min - Corrosion-resistant coatings extending service life beyond 20 years
