| Feature | NAS523 | NAS412 | AN960 | | :--- | :--- | :--- | :--- | | Material | Non-Metallic (Nylon, Teflon) | Metallic (Steel, Corrosion resistant steel) | Metallic (Aluminum, Brass, Steel) | | Washer Type | Captive (retained on screw) | Flat | Flat / Countersunk | | Primary Use | Insulation, Anti-vibration, Sealing | Structural joints, High load | General aviation, Low cost | | Plating Req. | Not applicable (non-metal) | Cadmium or Zinc | Cadmium or Phosphate | Once you have obtained the official nas523 pdf
