Self-locking lock nuts are specialized fasteners designed to resist loosening under vibration, torque, and dynamic loads without requiring additional components like washers or adhesives. They feature built-in locking mechanisms that create friction or mechanical interference to stay securely fastened.

Types of Self-Locking Lock Nuts

1. Nylon Insert Lock Nuts (Nyloc)

   • Contains a nylon ring that deforms against the bolt threads, creating friction.

   • Reusable to a limited extent (nylon may wear out after repeated use).

2. All-Metal Lock Nuts

   • Made entirely of metal with deformed threads or crimped sections.

   • Resistant to high temperatures (unlike nylon inserts).

   • Used in aerospace, heavy machinery, and high-heat environments.

3. Prevailing Torque Lock Nuts

   • Features a slightly distorted thread that increases resistance when tightened.

   • Maintains locking ability even after multiple installations.

   • Common in industrial and structural applications.

Selection Considerations

• 材質： Choose steel, stainless steel, or brass based on corrosion needs.

• Temperature Range: Nylon inserts fail at high temps (~250°F/121°C max).

• Reusability: Nyloc nuts wear out; all-metal nuts last longer.

• Torque Requirements: Some nuts require higher installation torque.

Self-locking nuts are essential for safety-critical and high-vibration applications. Would you like recommendations for a specific use case?
