Overview
EN ISO 16584:2002 (ISO 16584:2002) defines requirements for open end blind rivets with break pull mandrel and protruding head where the rivet body is a nickel‑copper alloy (NiCu) and the mandrel is either steel (St) or stainless steel (SSt). The standard covers nominal diameters from 3.2 mm to 6.4 mm and specifies dimensional ranges, mechanical properties, material/finish guidance and application data for these blind rivets. It was adopted by CEN as EN ISO 16584:2002.
Key topics and requirements
- Scope and types: Open end blind rivets, break pull mandrel, protruding (rounded) head; NiCu body with St or SSt mandrel; d = 3.2, 4, 4.8, 6.4 mm.
- Dimensions and tolerances: Rivet body and mandrel dimensions, recommended grip ranges and clearance hole diameters are specified (clearance holes slightly larger on access side may be used for alignment).
- Materials and finishes:
- Rivet body: nickel‑copper alloy (NiCu), plain (natural) finish.
- Steel mandrel: manufacturer’s choice of finish (e.g., phosphate & oil or zinc coating).
- Stainless steel mandrel: plain finish.
- Mechanical properties (minimum/maximum values given for each nominal diameter tested per ISO 14589):
- Examples: for d = 3.2 mm - shear ≥ 1 400 N, tensile ≥ 1 900 N, mandrel break ≤ 4 500 N; for d = 6.4 mm - shear ≥ 5 500 N, tensile ≥ 6 800 N, mandrel break ≤ 14 700 N.
- Mandrel performance:
- Push‑out resistance must exceed 10 N (ISO 14589).
- Mandrel head retention loads are defined (e.g., 15 N for 3.2 mm up to 30 N for 6.4 mm).
- Workmanship & acceptance:
- Rivets must be free from burrs and defects and show no cracking at 5× magnification after setting.
- Acceptance inspection per ISO 3269 unless otherwise agreed.
- Designation example: Blind rivet ISO 16584 - 4×12 - NiCu/St (4 mm diameter × 12 mm length, NiCu body, steel mandrel).
Applications
- Commonly used in sheet metal assembly, vehicle bodywork, HVAC, electrical enclosures and other blind‑side fastening where access to one side only is available.
- Selected for corrosion resistance and specific mandrel strength requirements where NiCu body and St/SSt mandrels are appropriate.
- Useful in manufacturing, repair, maintenance and construction tasks requiring consistent mechanical performance and standardized dimensions.
Who should use this standard
- Fastener manufacturers specifying design and production tolerances.
- OEM engineers and product designers specifying blind rivets for assemblies.
- Quality, procurement and test engineers conducting acceptance, mechanical testing and inspection.
- Technical writers and standards compliance teams preparing procurement specifications.
