ISO 16583:2002

Overview

ISO 16583:2002 defines dimensional, mechanical and application data for open end blind rivets with a break‑pull mandrel and countersunk head. It covers rivets with a copper (Cu) body and mandrels of steel (St), bronze (Br) or stainless steel (SSt), with nominal diameters from 3 mm to 4.8 mm. The standard sets sizes, material/finish guidance, mechanical performance limits and acceptance/testing references for reliable one‑side fastening.

Key topics and requirements

• Scope and sizes: Nominal diameters covered are 3, 3.2, 4 and 4.8 mm; rivet lengths and recommended grip ranges are provided in the standard (see Table 1).
• Materials & finishes:
  • Rivet body: copper, plain (natural) finish.
  • Mandrel: steel (surface treatment at manufacturer’s discretion, e.g. phosphate/oil or zinc), bronze and stainless steel mandrels plain.
• Dimensional rules / design formulae (Annex A):
  • Shank diameter: d_max = d_nom + 0.08 mm, d_min = d_nom − 0.15 mm.
  • Head diameter: d_k_max = 2.1 × d_nom (rounded).
  • Head height: k_max = 0.415 × d_nom.
  • Clearance hole: h1_max = d_nom + 0.2 mm, h1_min = d_nom + 0.1 mm.
• Mechanical properties (tested per ISO 14589):
  • Minimum shear loads (N): 3 mm → 760; 3.2 mm → 800; 4 mm → 1 500; 4.8 mm → 2 000.
  • Minimum tensile loads (N): 3 mm → 950; 3.2 mm → 1 000; 4 mm → 1 800; 4.8 mm → 2 500.
  • Maximum mandrel break loads (N): 3 / 3.2 mm → 3 000; 4 mm → 4 500; 4.8 mm → 5 000.
• Additional performance:
  • Mandrel push‑out resistance must exceed 10 N.
  • Mandrel head retention test loads (N): 3/3.2 mm → 15; 4 mm → 20; 4.8 mm → 25.
• Workmanship & acceptance: Rivets must be free of burrs and defects; no cracking at 5× magnification after setting. Acceptance inspection follows ISO 3269 unless otherwise agreed.
• Designation example: Blind rivet ISO 16583 - 4 ×××× 12 - Cu/St (for a 4 mm × 12 mm Cu body / steel mandrel rivet).

Applications and users

• Practical uses: one‑side fastening where a countersunk head is required (flush finish) - e.g., electronics enclosures, HVAC panels, automotive trim, light structural assemblies and general sheet‑metal work.
• Who uses it:
  • Fastener manufacturers and tool suppliers (design, production, quality control).
  • Mechanical and product design engineers specifying fasteners.
  • Procurement and standards compliance teams.
  • Test and inspection laboratories performing acceptance testing.
