Helicoil

Helicoil is wire thread inserts used to create internal screw threads in materials that are too soft to support a traditional screw thread. These inserts are made from high-strength, corrosion-resistant stainless steel wire that is wound into a helical shape, resembling a tightly coiled spring.

Key Features and Benefits:

1. Strength and Durability: Helicoil inserts provide high-strength threads that are resistant to wear and corrosion. They distribute the load over a larger area, enhancing the strength of the threaded connection.
2. Thread Repair: Helicoil inserts are commonly used to repair damaged or stripped threads, restoring them to their original condition and extending the life of the component.
3. Thread Reinforcement: In softer materials, such as aluminum or magnesium, Helicoil inserts reinforce the threads, preventing damage and ensuring they can withstand repeated use and high loads.
4. Precision: These inserts are designed to provide accurate and consistent threading, which is crucial for applications requiring high precision.
5. Ease of Installation: Helicoil inserts are easy to install using standard tools. They are inserted into pre-drilled holes and then locked into place, providing a secure and reliable threaded connection.

Applications:

• Automotive: Used in engine blocks, transmission cases, and other components where durable threads are essential.
• Aerospace: Ensures reliable thread performance in critical applications such as aircraft engines and structural components.
• Electronics: Provides strong and reliable threads in delicate electronic housings and components.
• Machinery: Used in industrial machinery for creating and repairing threads in soft or damaged materials.

How It Works:

1. Drill: The damaged or undersized hole is drilled to a specific size.
2. Tap: A special tap is used to cut new threads in the hole.
3. Insert: The Helicoil insert is screwed into the newly cut threads using an installation tool.
4. Break Off Tang: The tang (a small protruding piece of the insert) is broken off, leaving a clean, durable thread.

Advantages:

• Enhanced Load Distribution: The insert spreads the load over a larger surface area, reducing stress on the parent material.
• Corrosion Resistance: Made from stainless steel, Helicoil inserts resist rust and corrosion, even in harsh environments.
• Cost-Effective: Provides a cost-effective solution for repairing or reinforcing threads without needing to replace expensive components.

In summary, Helicoil inserts are essential components in many industries, providing reliable and durable threading solutions for both new applications and repairs.
