company news about Blind Rivets Explained: Types, Working Principles & Industrial Applications

Discover how POP, Multi-Grip, and other blind rivets work. Learn installation best practices, material compatibility, and industry-specific uses for secure fastening.

Blind rivets solve 85% of single-sided fastening challenges in aerospace and automotive manufacturing. This guide combines ASME and ISO standards with engineering insights to optimize rivet selection for vibration resistance, material compatibility, and load capacity.

4 Critical Blind Rivet Types Compared

Case Study: Boeing 787 uses 22,000+ multi-grip rivets per airframe, accommodating 0.5–12mm material stacks.

Working Principles & Installation

1. POP Rivets (DIN 7337)

• Mechanism: Mandrel pull-up expands rivet body
• Tools: Hand/pneumatic pullers (2,500N force)
• Advantage: 15-second installation time

2. Hem-Fix Rivets (ISO 16582)

• Process: Dual-sided clamping via tapered expansion
• Materials: Compatible with steel-aluminum joints
• Benefit: 0.02mm leak-proof seal creation

3. Mono-Grip Rivets (ASME B18.1.3)

• Design: Single diameter for fixed material stacks
• Installation: 45° gun angle for optimal expansion
• Use Case: Bridge construction (M16–M24)

4. Multi-Grip Rivets (NASM 1312)

• Adaptability: 3:1 grip range ratio
• Testing: 100,000+ vibration cycles (SAE J1459)
• Aerospace Spec: 0.5–14mm stack accommodation

Material Compatibility Guide

Industry-Specific Solutions

1. Automotive Manufacturing (IATF 16949)

• Challenge: Mixed-material EV battery enclosures
• Solution: Hem-Fix rivets with 2.5kN clamp force

2. Aerospace (AS9100)

• Requirement: 0.3–12mm stacked composites
• Fix: Multi-grip titanium rivets (M8 @ 110Nm)

3. Renewable Energy (IEC 61400)

• Wind Turbine Blades: Monel rivets withstand 25m/s winds
• Solar Racking: Aluminum POP rivets (salt spray 1000h)

Installation Best Practices

1. Hole Preparation

   • Diameter: Rivet size +0.1mm
   • Deburr with 45° chamfer (ISO 13715)

2. Tool Selection

   Rivet Size	Force Required	Tool Type
   M3–M5	1,500–3,000N	Hand lever
   M6–M10	4,000–8,000N	Pneumatic
   M12+	10,000N+	Hydraulic

    

3. Quality Control

   • 100% mandrel break inspection
   • 10% sample cross-section analysis

5 Common Failure Modes & Fixes

1. Loose Installation

   • Cause: Insufficient pull force
   • Fix: Re-rivet with +15% force

2. Mandrel Jamming

   • Prevention: Lubricate with Molykote 111

3. Corrosion Creep

   • Solution: Switch to Monel/Alclad rivets

4. Hole Elongation

   • Prevent: Use steel back-up washers

5. Material Cracking

   • Fix: Preheat composites to 65°C
