NAS1130 inserts are high-performance, tangless helical coil screw thread inserts designed to provide durable, reliable internal threads in aerospace and high-reliability applications. Manufactured to National Aerospace Standards (NAS), these inserts are widely used to reinforce threads in softer materials such as aluminum, magnesium, and composites while maintaining precise thread integrity.
Engineered from formed wire with a diamond-shaped cross section, NAS1130 inserts are installed into a tapped hole to create a strong, wear-resistant internal thread that meets exacting aerospace specifications. They are commonly used in aircraft structures, engines, and defense systems, as well as in electronics housings and other lightweight assemblies where resistance to thread wear, vibration, and repeated assembly is critical.
Key Features & Benefits
- Tangless design eliminates the need for tang break-off, reducing foreign object debris (FOD) risk and improving installation efficiency
- Available in free-running and self-locking (K) configurations to meet varying torque and vibration requirements
- Provides enhanced thread strength and load distribution, extending the life of the parent material
- Resistant to vibration, shock, and fatigue, making them ideal for critical aerospace assemblies
- Typically manufactured from corrosion-resistant stainless steel with optional finishes such as dry film lubricant
- Compatible with standard UNC and UNF thread forms
