🔩 Nylon Dome Nut – Protective, Non-Corrosive Cap Nut | Neo Fasteners
Nylon Dome Nuts, also known as Nylon Acorn Nuts or Nylon Cap Nuts, are non-metallic fastening components with a smooth, rounded dome-shaped top that covers the exposed threaded end of a bolt or stud.
These nuts not only provide a clean, finished appearance but also protect threads from damage, corrosion, and accidental contact. Made from engineering-grade Nylon 6/6, they are lightweight, corrosion-free, non-conductive, and chemically resistant, making them ideal for applications where metal fasteners may cause rust, electrical conduction, or chemical reactions.
✅ Key Features
- Protects exposed threads from dirt, moisture, and impact
- Non-corrosive – Will not rust or oxidize in outdoor or marine use
- Electrically insulating – Safe for electrical applications
- Lightweight – About 1/6th the weight of metal nuts
- Non-magnetic – Suitable for sensitive instruments and MRI environments
- Smooth, safe finish – Prevents injuries from sharp bolt ends
- Decorative look – Ideal for visible fastening points
