Notes from the standard

  • Dash number: diameter in 32nds of an inch, then length in 16ths. Copper rivets carry C before the diameter (AN420-C2-2).
  • Add P after the dash number for an iron rivet with cadmium or zinc plate: AN420-2-2P is mild steel, 2/32 in diameter, 2/16 in long, cadmium or zinc plated.
  • Head angle 90°. Unless otherwise specified, fraction tolerances ±1/64 in.
  • Cancelled after 10 December 1965: use MS20427. No superseding part for -3-18, -3-20, -C3-18, -3-18P, -C3-20, -3-20P, -C4-18, -C4-20, -C4-22, -C4-24, -C4-28, -C5-18, -C5-20, -C5-22, -C5-24, -C5-28, -C6-28, -C6-32.
  • Rivets must be true to form, concentric and free from injurious scale, fins, seams and all other injurious defects.
  • Approved data governs. Use the rivet the SRM, drawing or IPC calls for.
