Aerospace Inserts: High-Performance Threaded Inserts for Aerospace Applications

In the aerospace industry, every fastening component must meet the highest standards of strength, safety, and durability. One vital component that ensures secure, long-lasting connections in aircraft and spacecraft structures is the aerospace insert. These threaded inserts for aerospace applications provide reinforced threads in soft materials and ensure reliable performance in extreme environments.

Types of Aerospace Inserts for Aircraft and Spacecraft

Helical Wire Aerospace Inserts

Helical wire aerospace inserts—commonly known as heli-coil inserts—are made from coiled stainless steel wire. They are ideal for reinforcing internal threads in lightweight materials like aluminum. These aerospace inserts are commonly used to repair stripped threads or enhance thread strength in soft substrates without adding excessive weight.

Key-Locking Aerospace Inserts

Key-locking aerospace inserts, such as Keenserts, are precision-machined metal inserts with locking keys that prevent rotation and pullout. These aerospace threaded inserts are highly resistant to vibration, making them suitable for critical components such as avionics, engines, and landing gear.

Solid Threaded Inserts for Aerospace Structures

Solid aerospace inserts are typically machined from stainless steel, titanium, or other aerospace-grade alloys. These inserts offer maximum thread strength and load capacity. Used in high-stress aerospace components, they provide a robust solution where failure is not an option.

Floating Aerospace Inserts for Misalignment Compensation

Floating aerospace inserts allow for slight lateral movement, making them perfect for multi-hole panel assemblies where exact alignment is challenging. These inserts are widely used in modular aircraft interiors, satellite components, and avionics mounting systems.

Key Advantages of Using Threaded Inserts for Aerospace Applications

Vibration resistance – Aerospace inserts prevent loosening under dynamic flight conditions.

Enhanced thread strength – Especially in lightweight or composite materials.

Corrosion protection – Aerospace inserts are made from rust-resistant alloys.

Repeatable assembly – Enable multiple assembly/disassembly cycles without damaging the base material.

Lightweight and compact – Ideal for weight-sensitive aerospace designs.

Applications of Aerospace Inserts in Aircraft and Space Systems

Aerospace inserts are essential in a wide variety of applications, including:

Fuselage and wing panel assemblies

Jet engine and turbine components

Satellite enclosures and payload structures

Cabin seating, interiors, and storage systems

Avionics housings and control panels

Composite airframe parts requiring metal threads

Materials and Standards for Aerospace-Grade Threaded Inserts

All threaded inserts for aerospace use high-performance materials such as:

• Stainless Steel (303, 316)
• Titanium Alloys
