Specifications of Tangless Heli-Coil
- Product Details
A tail-less Heli-Coil (or tangless Heli-Coil) is a type of wire-thread insert designed without the small "tang" typically found in traditional Heli-Coil inserts. The tang is a small, protruding piece of wire at one end of a standard Heli-Coil used to facilitate installation. In a tail-less design, the tang is eliminated, making the insert easier to use and offering additional benefits.
Key Features of Tail-less Heli-Coil
No Tang for Installation:
Unlike traditional Heli-Coil inserts, which require breaking off the tang after installation, tail-less inserts are designed to install directly without needing tang removal.
This eliminates the risk of tang fragments remaining in the assembly, which is especially critical in sensitive applications like aerospace or electronics.
Ease of Use:
Installation is simplified as there is no need for tang removal.
Installation tools grip the insert via a notch or specialized design at both ends.
Bidirectional Installation:
Tail-less Heli-Coil inserts can be installed from either end, adding flexibility during assembly.
Material and Design:
Typically made of the same corrosion-resistant stainless steel as standard Heli-Coil inserts.
Suitable for high-precision applications.
Applications
| Industry | Application | Reason for Tail-less Use |
|---|---|---|
| Aerospace | Fasteners in aircraft components | Avoid tang debris in critical systems. |
| Electronics | Threads in sensitive devices | Prevent loose tangs from causing electrical shorts. |
| Automotive | High-performance engine components | Simplify installation and ensure reliability. |
| Medical Devices | Implants or equipment | Avoid contamination and simplify maintenance. |
Advantages of Tail-less Heli-Coil
| Feature | Benefit |
|---|---|
| No tang to remove | Simplifies installation and reduces risk of leftover debris. |
| Clean installation | Ideal for applications where foreign object debris (FOD) must be avoided. |
| Reversible design | Insert can be installed from either end, adding versatility. |
| Time-saving | Eliminates the step of tang removal, reducing installation time. |
Installation Process for Tail-less Heli-Coil
Prepare the Hole:
Drill and tap the hole to the appropriate size based on the insert's specifications.
Load the Insert:
Use a specialized tail-less Heli-Coil installation tool designed to grip the insert.
Install:
Screw the insert into the tapped hole using the installation tool.
Verify:
Ensure the insert is flush with the surface and the threads are secure.
Why Choose Tail-less Heli-Coil?
Tail-less Heli-Coil inserts are ideal when:
Contaminants like loose tangs cannot be tolerated.
High reliability and precision are required.
Simplified installation and faster assembly processes are needed.
