Overview
ISO 16584:2002 defines the international standard for open end blind rivets with break pull mandrels and protruding heads, made from a nickel copper (NiCu) body combined with either steel (St) or stainless steel (SSt) mandrels. This standard specifies the dimensional, mechanical, and application requirements for these rivets with nominal diameters ranging from 3.2 mm to 6.4 mm.
Developed by ISO Technical Committee ISO/TC 2 on Fasteners, this standard provides uniform guidelines to ensure reliable performance and quality in fastening applications where blind rivets are used to join materials from one side, especially where access to the back of the joint is not possible.
Key Topics
-
Rivet Design and Dimensions
The standard details the exact dimensions for rivet body, mandrel, head size, and grip ranges. It includes:
- Maximum and minimum diameters and lengths
- Recommended grip ranges for various nominal dimensions
- Clearance hole diameters required in components to accommodate the rivet for correct assembly
-
Materials and Finish
Rivet bodies are made from nickel copper alloy (NiCu) to provide corrosion resistance and strength, with mandrels made from either steel or stainless steel depending on application needs. Surface finishes:
- Rivet bodies have natural plain finish
- Steel mandrels may have phosphate and oil or zinc coating
- Stainless steel mandrels have a natural finish
-
Mechanical Properties
Performance requirements include specified minimum shear loads, tensile loads, and maximum mandrel break loads tested based on ISO 14589. The standard also covers:
- Mandrel push-out resistance load thresholds
- Mandrel head retention test loads ensuring the mandrel remains secured after installation
-
Quality and Workmanship
Rivets must be free from burrs and defects, with well-formed heads and shanks. After setting, rivets should show no cracking under 5x magnification.
Acceptance inspection follows ISO 3269 to verify compliance.
Applications
ISO 16584:2002 blind rivets with NiCu/St or NiCu/SSt construction are ideal for industrial and manufacturing fastening solutions where:
- Access is limited to one side of the parts being joined
- Strong, reliable fastening is required with corrosion resistance
- Precise dimensional control is needed for consistent performance
- Steel or stainless steel mandrel options ensure suitability for varied environments, including potentially corrosive or high-stress conditions
Typical industries using these rivets include automotive, aerospace, electronics enclosures, construction, and machinery assembly.
